The textbook provides an adequate foundation for basic geological topics like the minerals, the rock types, surface processes and the hydrological cycle, and internal processes related to plate tectonics.
Occasional use of emotional language like "disturbingly" but most of the language is relatively neutral. Occasional errors related to age of the text and needing to be updated (for example, Hawaiian volcanic eruptions, European heat waves, current climate data).
The textbook contains some outdated events and statistics including 2019 heatwaves in Europe that have been overshadowed by more recent ones. Most updates on geologic events (volcanic eruptions, other disasters) would take relatively little time. The text focuses frequently on British Columbia and Canadian geology, making it more relevant for students in those geographic areas.
Occasionally, terms are left undefined except in the Glossary (and sometimes not even there), which could lead to confusion for students. The Plate Tectonics chapter, for example, is towards the end of the textbook, although plate boundaries and related processes are discussed throughout the textbook. It would be more useful to have this chapter towards the beginning of the textbook to more clearly relate other topics to this unifying theory of Geology.
Excellent structure with learning objectives, chapters broken into clear sections, "exercises" relevant to various sections, and summaries and summary questions to help frame student learning and instructor teaching.
Each chapter is divided into clearly titled sections that would be easy to assign or leave out of course reading assignments. Especially if the instructor and students are not in BC or Canada at all, some of the sections focused on Canada could be left out and replaced with more geographically relevant geology.
The Plate Tectonics chapter, for example, is towards the end of the textbook, although plate boundaries and related processes are discussed throughout the textbook. It would be more useful to have this chapter towards the beginning of the textbook to more clearly relate other topics to this unifying theory of Geology.
You cannot navigate directly to chapters in the table of contents through links, but the interface is relatively free of navigation issues and images are not distorted. Some author-generated graphs and diagrams are a bit pixelated.
Use of commas is irregular.
The majority of examples are focused on British Columbia and/or Canada, but there are many examples from the U.S. and, to a lesser extent, other countries.
A good basic geology textbook, and especially relevant if the instructor/students live in Canada or the northernmost U.S.

This text book covers the content that the most popular introductory physical geology textbooks cover in similar detail, and probably exceeds the detail in some areas without feeling over lengthy. For context, in my program we have divided our traditional physical geology course for geoscience majors and other STEM majors into two separate 200 level courses (Solid Earth, and Fluid Earth), but use a single expansive text from a traditional publisher for both courses because it covers essentially all aspects of introductory physical geology. I would rate the content of this text as being expansive enough that it could easily replace the current non-OER text we use now because it easily provides enough material for the two separate courses. There are even chapters relating to the geologic history or western Canada, which is relevant for where this book was designed to be utilized. This could easily be remixed to add place-based content for wherever this text might be used. The glossary is well organized, and has a lengthy list of defined terms. In addition to definitions for each term, next to every entry there is a link to the chapter where the term first appears in the text. There is also a link to the glossary in the table of contents, so it is easy to find and can be opened in a separate tab so that the reader can utilize the glossary while they are reading the text.
The text is accurate, and as far as I can free from major errors (none that I noticed). For the content areas I am most familiar with (Tectonics, Geologic Structures), I read in detail and note that the content in my assessment is accurate. My only complaint here would relate to a few minor points of clarity. In the Earth Sciences, probably the topic most ripe for bias would likely relate to climate change and anthropogenic effect on climate. Upon review of this section, the text offers an unbiased explanation of the data and issues at hand, and presents the consensus view among scientists about the effect humans have on climate change, as well as recent climate observations that support this view.
The material in the book seems to be up to date and incorporates our modern understanding of many concepts in Earth Science. As an example, the charts in the anthropogenic climate change section include temperature data from 2010 to 2020. And, many of these figures are from sources that are frequently updated and are in the public domain (e.g., NASA Earth Observatory figures and charts).
In some sections, the text could use a little less technical jargon when introducing a topic, and find some more everyday examples to illustrate a concept. For example, in the Geological Structures section, there is a technical explanation of stress and strain, and the ways materials deform, which is actually well done. However, adding in illustrations or explanations of what this could look like in everyday materials a person might encounter outside of Earth materials might go a long way to help introduce a complicated topic like this. Additionally, in some areas the explanations or illustrations could be expanded just a little more without significantly increasing the length of sections or the text as a whole. For example, in this same chapter discussed above, the idea of faulting is introduced but there is a lack of detail on how we define different types of faults (dip-slip vs. strike-slip), and we can determine the difference between the two with illustration. It just mentions that there are different types of fault, and that normal faults accommodate extension, reverse faults accommodated compression, etc. Without an illustration of what a hanging wall and footwall are, and how they are defined, I could see it being very vague to the reader learning about these concepts for the very first time.
Each chapter is laid out in a consistent fashion, with a box at the beginning of every chapter outlining the learning objectives and giving a broad overview of the concept of each chapter. Chapters are divided up thematically in a way that makes logical sense, and similar to the way most physical geology textbooks are divided thematically. Additionally, each chapter is divided into smaller sections in a way that is consistent throughout the text. The tone of the writing is also consistent throughout. Figures that were created by the author are also consistent in style, which I can appreciate.
Sections within chapters are relatively short and digestible, and broken up into individual pages. Other OER physical geology textbooks I have used or skimmed over had much longer blocks of text. Using a different OER test for an intro to geology course recently, I found it difficult organize reading assignments because I had to spend a fair amount time going through the text directing students specifically which portions of a section to read and which to skip because the chapters were quite long and not broken into individual section pages. This text I can envision easily assigning and linking to the shorter sections without having to spend a lot of time micromanaging reading assignments.
The organization of this text for the most part is similar to other comparable physical geology textbooks. And as with the other books, there is some variation in the order that topics are introduced. However, I find in my mind, and experience teaching introductory geology, that discussing the origin of the universe and Solar System, then Plate Tectonics makes the most sense because many other topics are dependent on contextual understanding of these big picture ideas (e.g., the structure and differentiation of the earth, metamorphic rocks, igneous rocks and volcanoes). This book places Plate Tectonics in the middle part of the book, and Origin of Earth and Solar System as the final chapter. That being said, it ultimately doesn’t matter that much. Given the great interface and the way the chapters and chapter sections are organized, it is very easy to organize a course in whatever order you would like, and jump around to the different chapters. Additionally, colored boxes within text are organized in consistent way that guide the reader. Black boxes at beginning of chapter lay out the learning objectives for the chapter, blue boxes within chapter sections are embedded exercises and end of chapter review questions, green boxes summarize the key take away from a chapter section, and red boxes are extended discussions to clarify topics or address and clarify common questions that a reader might have.
One of the first things that stuck out to me when skimming through the 1st edition was that the in text images were a bit small. You had to click on them if you really want a good look at the figures. I notice in the 2nd edition, this has been fixed and the in-text images are an ideal size now that make it easy to read. At first on the desktop version, it took me a while to notice the navigation bars to move ahead to the sections, go back to the previous section, or jump to the top of the page. But once I found them, I thought their location is well implemented. The chapter links and sections within chapters are nicely organized in a dropdown menu at the top of the page, which when open is located on the left hand side of the text in a way that allow you to navigate to different sections without blocking the text. Within the text, there key words highlighted in red that you can click to show the definition of the term. Additionally, I checked how the text appears on a mobile phone and found the layout is nicely adapted to mobile. The only issue is that some in text table with a large amount of columns don’t display as nicely and you have to scroll sideways or zoom out to read all the columns.
No grammatical errors as far as I noticed.
I did not notice any sections or text that would be considered culturally insensitive or offensive. Generally, the issue of being inclusive of a variety of races, ethnicities, and backgrounds is not applicable because the majority of the text is focused on the explanation of physical processes occurring on earth. However, in the section discussing the Geological Renaissance of the Mid-20th century, there is a lack of discussion of important pioneering women that were also instrumental (e.g., Tanya Atwater, Marie Tharp).
The textbook layout and content are very similar to other (costly) Earth Science textbooks. It is also quite easy to view/use the index, which can be broken down into sections to quickly find a specific part. read more
The textbook layout and content are very similar to other (costly) Earth Science textbooks. It is also quite easy to view/use the index, which can be broken down into sections to quickly find a specific part.
I reviewed a sampling of chapters and could not find any errors or biases in the text. The textbook includes all of the content that I would want to cover in my introductory Earth Science course at Virginia Tech.
Most of the chapters are up-to-date and will not change drastically in the near-future. However, the climate change chapter (Ch. 19) could use a major update. The section on anthropogenic climate change uses graphs/data from 2015 at the latest (some from 2010, over a decade ago) and of course, we have more recent data available as of writing this review in 2021. It is not only a bit out-of-date but also lacking more detail for that chapter, seeing as it is increasing in importance over time. For that chapter, the instructor would need to provide many more up-to-date resources to fully cover the topic.
This textbook is written in an easy-to-understand way, especially for an introductory Earth Science course. The glossary is easy to use for any technical terms, and I don't think college students will have any issues understanding the text.
This book is similar to other introductory Earth Science textbooks in that each chapter begins with a quick overview and then the chapter is broken down into a few sections. Keeping the same consistent framework is important, especially for self-paced online courses like the one I am teaching. This book does a great job with consistency.
As mentioned above, each chapter is divided into smaller sections in this textbook. Instructors can assign only partial chapters if they want, and using an LMS like Canvas should allow you to easily break up the textbook into smaller chunks for reading assignments so that students aren't presented with huge blocks of text at a time.
This textbook follows a similar logic to most of the introductory Earth Science textbooks I have used before, starting on a smaller scale with minerals/rocks and ending on a much larger scale with climate change and the solar system. It covers many of the same topics in the same order I am used to seeing in Earth Science textbooks, although this one does include a chapter specific to the author, "Geological History of Western Canada."
This book is quite easy to navigate, but I do wish that some of the images and graphs were larger and better quality. In other online textbooks, I can click on an image/graph and it will expand to fill the computer screen while still being high-quality. With this textbook, many of the images are indeed high quality but some of them barely get larger when I click to expand, as if the image quality isn't high enough to fill the entire screen and still look good. Other than that, there really aren't any features that may distract or confuse the reader--this textbook is well-organized in that aspect.
As far as I could tell, this textbook does not have any glaring grammatical errors (I reviewed a sampling of chapters).
As this is a physical science topic, the author focuses on the scientific study of the Earth and does not use any culturally insensitive examples or text in any way.
I am so glad that this textbook is available in the open source library. I have been searching for an accurate and well-organized open source textbook to use in my intro to Earth Science course to help students avoid the ever-increasing cost of textbooks, especially one that most of them will likely only use for one semester (this is an Intro to Earth Science course that mainly consists of non-majors). I teach up to 600 students per semester in this course, so that is an incredible amount of money saved!
I do wish there were more free resources to go along with this textbook for the instructor, but I have been teaching long enough that I can put together exercises and assessments myself. However for a newer instructor, I would likely recommend utilizing a textbook that includes online resources for instructors as well as students (yes, one that is paid for by students) before jumping straight to an open source textbook like this one where you would be largely responsible for creating all resources yourself.
This book is fairly comprehensive, occasionally a bit advanced for introductory levels. Often, this text goes on to describe geological formations in the BC/ Vancouver area due to the author's location. read more
This book is fairly comprehensive, occasionally a bit advanced for introductory levels. Often, this text goes on to describe geological formations in the BC/ Vancouver area due to the author's location.
The content is highly accurate with no contextual errors. The text would benefit from one more additional proof reading. There is only bias in terms of how often the Vancouver/ BC area is referenced.
Due to the slow progress of geological time, this book is absolutely relevant and not likely to be out of date any time soon.
Some descriptions could use some further clarification, or simplification. Example, the description of how Wegener came upon his theory of continental drift is a bit wordy. The book does a great job in the breakdown of rock origins, soil layers, and groundwater.
The downloaded book is very consistent. The virtual online book has some definition errors which have confused students.
Page layouts, short subject callouts, references, and tables are laid out well. I was able to reorganize some chapters for coursework, with only a minor bit of repetition.
The book may do well to reevaluate it's organization. I reorganized by placing geological time at the end of my course structure and paired volcanism and plate tectonics.
Overall, the book interface functions well in both PDF and online formats. Adding a navigation bar to each page of the online version would be helpful.
One further proofreading of the text would clear up the minor stand out grammatical errors.
Cultural sensitivity is not pertinent to the subject matter. There are no indications that races, ethnicities, and backgrounds are viewed in any disparaging manor, as they are not discussed.
The text includes some great questions as the end of each chapter. However, the answers to each questions are also provided in the back, discouraging a student from doing the work. Creating additional question sets for each chapter may be necessary.

This text covers all of the subjects needed for an introductory geology course at a level of detail which is appropriate for both non-majors and students beginning their geology training. I used this as one of two primary texts in my Geology 1 class this spring and was pleasantly surprised at the coverage and depth of information.
The 2nd edition of this text appears to be up to date with the latest information on the topics discussed.
The author provides numerous examples and applications of the concepts presented in each chapter. These examples do focus primarily on Western Canada, which may be slightly less engaging for students not working in that area. This can be easily remedied with supplemental examples in lecture, however, and does not outweigh the benefits this text brings to a class.
This book is written in a very clear and digestible manner, which is a major boon for introductory courses. Topics are presented in an almost conversational manner with frequent figures and examples. The overall reading experience is rather engaging. Learning objectives are clearly stated at the beginning of each chapter, which closes with a summary of information and a number of review questions. The answers to these questions are provided in the appendix, which allows them to serve as a self check for student comprehension.
Each chapter is laid out in a consistent manner, subdivided into topics as necessary. Each chapter begins with a clear introduction and clearly stated learning objectives. Exercises are presented in boxes spread throughout the text alongside the relevant subject matter, in addition to review questions at the end of every chapter. Terminology used is consistent throughout the text.
Chapters are largely self contained and can be readily assigned individually in almost any order. Within each chapter the material is further subdivided into a number of clearly marked sections dealing with a particular focus area.
The book largely follows the standard order of subjects as taught in an intro course, beginning with basic principles, minerals, and the rock cycle before progressing to major processes and Earth history. Some instructors will prefer to delve into plate tectonics earlier in the course (it is presented here as chapter 10 of 22), but this can be easily done due to the modular nature of the text.
The interface is easy to navigate and well laid out. I primarily used the online version of the book, not the downloadable pdf. The online version scrolls easily through each chapter, with a navigation bar on the left side linking to subsections and other chapters. Glossary terms are defined in roll over links. As other reviewers have noted, there is no index. The web version of the book does have a search function as part of the interface, however, which can functionally replace an index.
I noted no major grammatical errors during my use of the text.
Neither I nor my students had any complaints about the text. As mentioned before most of the examples provided focus on Western Canada, but this is in no way excludes any groups.
Overall I was very pleased with this textbook for my introductory level geology courses. This was my first foray into open educational resources and I must say I was pleasantly surprised. This textbook is through and informative without being so dense as to be off-putting to beginning students, which can sometimes be a hard balance to strike. It is extremely effective at what it sets out to do and I highly recommend it.

The book is organized in a logical (yet, not traditional) way. I find useful that important concepts were in bold and linked to the glossary. In addition, some core ideas of the chapter are organized in a way that for students (in faculty) is an easier way to find.
Content is accurate. However, the majority of the examples are rooted in Canada (where the publishers are). For me (who investigate and use place-base education pedagogy), I find difficult to based my lectures just in the examples proposed in the book.
This book introduces relevant topics with concurrent examples, besides your traditional physical geology textbook. I find appropriate the introduction of climate change (especially anthropogenic CC or Anthropocene). Usually for this type of discussion, I use alternative sources as complementary. Another chapter that I found relevant is # 20. Geological resources are really topical nowadays. I usually cover this topic from the standpoint of society needs, career choices, and future geologic record.
The narrative of the textbook accessible and clear.
Framework seems consistent through the whole book
The structure of the book, suggest an alternative way of “chunking” material (ex. 19.3). I find is really useful. However, I also find that (depending the audience of the course) it could be too much material to discuss.
The book is organized in a logical (yet, not traditional) way. Some core ideas of the chapter are organized in a way that for students (in faculty) is an easier way to find.
The interface proposed in this book seems adequate. Sections (some) have exercises in the middle. This seems an interesting approach that is towards application, instead of memorization or conceptualization. In addition, the book can be accessed online (and all its components) or downloaded in PDF. The PDF version is heavy to download, but is available. Im consider this especially, because of the current situation that we are teaching this type of course (mostly online)
During this review, I did not found grammatical errors.
Chapters that are dedicated to Canadian geology, seems to provide Canadian cultural relevant material for Canadian students. That is a very targeted audience.

The textbook is a comprehensive introductory manual. It covers in good detail all the major aspects of physical geology. Where the discussion of certain topics is not extended, the instructor has the flexibility to add further information according to students’ specific needs and interests. A glossary and the reference to the chapter in which a specific term is explained are provided.
Content is accurate and unbiased.
The second edition has been recently published, thus the content is up-to-date. However, the chapters including statistics could require an update in a short period of time.
The text is well written and the author uses accessible and clear language for science and non-science majors. Various examples, illustrations, and photos increase the clarity of information. Learning objectives are outlined at the beginning of each chapter. The colored boxes contribute to point the attention to the important concepts, provide ideas for experiments, and engage students to self-assess their learning. The summary at the end of each chapter assists the reader to focus on the most important concept covered in the chapter.
The consistency of terminology is evident throughout the textbook. Style and structure of chapters are coherent through the book.
Each chapter can be read independently. Instructors can reorganized some chapters to better fit with specific course learning objectives.
The textbook is well organized and easy to read. However, it could create confusion introducing briefly the theory of plate tectonic in Chapter 1 and then resuming the topic in Chapter 10. Likewise, the concept of geologic time is briefly introduced in Chapter 1 and then the author revisits in more detail the topic in Chapter 8.
The text size and the font used make the book easy to read. In the PDF version, the links to external resources and table of contents are disabled. Resolution of several images should be improved, in particular the resolution of figures showing rocks and minerals.
The text appears to be error-free.
The text is not culturally insensitive or offensive in any way. Examples are mainly focused on a variety of localities from Western Canada. Some images of localities around the world are also shown.
This review is on PDF version of the second edition published in 2019. Overall, it is a good textbook that can be considered for adoption in introductory physical geology courses.

The second edition of this textbook covers all of the major areas of concentration seen in the most popular of current physical geology texts produced by the major publishing companies. In addition, the material presented in the textbook is covered at the level expected of in an introductory, college science course. A glossary is provided, along with hyperlinks to the chapter where each term is introduced. The hyperlinks are very helpful, and I can think of only a few other glossaries in similar texts that have a feature similar to this. The hyperlinks take you to the first page of the chapter where the term is introduced, but they do not take you to the specific page where the term is first used. If it took you to the specific page, that, it seems to me, would be much more beneficial . . . if for no other reason than because this textbook does not have an index. The fact that the textbook lacks an index was surprising to me. I really like this book! It is so much more than I expected to find when looking for an OER textbook for my geology class. But, I so really wish it had an index too! I’m sure making an index is tedious work, but this textbook (considering its length and breadth of material) would be greatly enhanced with the addition of an index. It’s like they hyperlinked the terms in the glossary to make-up for the lack of an index. That’s great, but the glossary does not come close to making-up for what a proper index could bring to this textbook.
As far as I can tell from using the textbook, I do not see or remember finding anything glaringly incorrect with this the material presented in this textbook. I did use the textbook this semester in my class, and I also never received any negative feedback from students concerning the textbook’s accuracy.
The textbook is up-to-date on the latest understanding of the concepts presented. This is the second edition of this textbook, and it is very well referenced throughout. Although, the textbook has one formal author, it is clearly noted which geoscientists helped review the textbook before publication. The textbook is very modular based. So, it’s easy to separate the chapters from the whole PDF document. This also makes it easy to add to and/or update information at any time.
The textbook is written at the college-level and is appropriate for an introductory course in Physical Geology.
I do see consistency throughout the text in regards to terminology used. I tell my students, "In geology, there are often at least five different ways to say the same thing." This textbook handles terms and their usage very well. I didn’t see multiple terms being used interchangeably that mean, essentially, the same thing. For example, I’ve seen the terms ‘stress’ and ‘pressure’ used interchangeably within the same chapter in other textbooks. This can be confusing to students, and, I’m happy to report, I did not see situations like this in this textbook. In addition to having a glossary with hyperlinked terms, it also does not use confusing and/or obsolete terms.
The textbook is very modular. It is easy to split the different chapters into their own PDF files. I do this in my class when presenting a new chapter or two within each new module in my LMS course shell. Still, I do give students a link to the entire textbook as one PDF (it’s a very large PDF file), because the individual chapters are hyperlinked to other parts of the textbook. Hyperlinking the chapters together is beneficial in many ways. But, when you remove one chapter from the text to make it into its own small PDF file, it breaks the hyperlinks. Because of this, when I just post one chapter, I am careful to point out to students that many (most/all?) of the hyperlinks within the chapter will not work. So, I refer them to the entire textbook PDF file if they need working hyperlinks.
The organization is very clear and orderly. For the most part, the chapters are arrange in a very similar order to almost every other geology textbook I have used/reviewed. The only major difference is the chapter on Plate Tectonics is not the second chapter in the textbook, following the Introduction. Most physical geology textbooks have adopted the style of presenting Plate Tectonics at the beginning of their texts since it is the fundamental unifying theory of all geological processes. Still, this textbook does present the major concepts of plate tectonics in the Introduction chapter. I still present Plate Tectonics at the beginning of the semester while using this textbook. So, covering material presented in Chapter 10 at the beginning of the course before returning back to Chapter 2 is not impossible or overly inconvenient. Still, having the Plate Tectonics chapter as Chapter 2, would be nice to see in the third edition.
The text size and font style used makes this textbook physically easy to read. Again, hyperlinks throughout the textbook make for easy use of and reference to figures, tables, the glossary, answers to exercise and review questions, etc.
I did not see any grammatical errors.
I did not notice any culturally insensitive or offensive language used within the textbook. That said, it would be nice to see a segment of each chapter devoted to the work of a current, innovative scientist involved in a research related to the material presented in the chapter . . . especially focusing on research contributed by women and minorities. In the US, the geosciences are need of diversity. We need to do all we can to show our students that anyone with an interest in science can make a career out those interests, regardless of their gender, age, race, sexual orientation, etc.
Overall, this is a great textbook! I’m very glad it exists. I will continue using it in my classes and am looking forward to seeing future editions developed. I am especially looking forward to seeing an index for the textbook developed soon too!

The book covers the usual topics from physical geology books. It has a glossary with active links in the text. However, it does not have an index. Some of the topical sections of the book are somewhat simplified, but depth could be added as needed by the course instructor.
The textbook contained no obvious inaccuracies.
The second edition of this text includes the most relevant examples of natural disasters. It seems it would be easy to make updates as necessary.
The book is well written. There are a few places where a bit more information or explanation would be helpful. The instructor could fill in where additional clarification would be needed.
Each chapter is set up in a consistent way. It is very easy to follow.
The book is organized well with units and subunits.
The organization was clear and followed what the common order in other textbooks. As with all textbooks, the instructor can choose the order to present the material. I don't think any major issues would arise by reorganizing the topics to better fit a specific course.
Most of the book had no issues. However, some of the images were not high quality and were blurry.
I did not see any grammatical errors.
The book described many Canadian features. Some instructors may need to supplement with regional examples.
I think this book is more than sufficient for an open-source book. I like the structure of each chapter: it begins with learning objectives, it has practice and application questions throughout the chapter, has a chapter summary, and review questions. There was also virtual field trips to help show examples and reinforce concepts. The textbook could easily be used for introductory geology courses.
Overall, the level of material is appropriate for an introductory physical geology textbook. There are some areas where the book could delve deeper. I think the coverage of mineral resources could be expanded, especially into the background of... read more
Overall, the level of material is appropriate for an introductory physical geology textbook. There are some areas where the book could delve deeper. I think the coverage of mineral resources could be expanded, especially into the background of how coal, oil, and natural gas each forms. The same could be said for the various types of metallic ore deposits.
As a geochemist, I appreciate the presentation of basic chemical principles at the start of the minerals chapter. This information is clearly presented at a level understandable to the reader, and it is timely, considering the content of the chapter. Not all physical geology textbooks mention this information. Chemical reactions are well-placed at various points in the book.
I did not note any inaccuracies in information, and was especially impressed that all the chemical formulas and reactions were correctly represented (i.e. capitalization, names, etc.), from a geochemist’s standpoint.
The textbook makes good use of references to local geologic features that can be found in various parts of Canada (mainly western Canada). This makes perfect sense as that is where the author is from. However, for readers not familiar with the locales mentioned (i.e. from a country other than Canada), those references may not be as helpful. I don’t feel this is an issue that would prevent me from using this text, as there are also many references to locales from other parts of the world. Rather, it gives me an opportunity to supplement the text information with references that are more local to where my students are geographically.
Topics are described clearly, with many references to photos and tables in order to better convey the information.
The text is written at an appropriate reading level.
The glossary is quite extensive and helpful.
The lack of an index is noted at the back of the book, but may be less important for a digital version of a text that can be more easily searched.
Chapters are set up in a very consistent framework, starting with an introduction before leading into the topics being covered. Wording and terminology are quite consistent throughout the text.
Each section within the chapter is nicely modularized, with pretty much all of the information needed being within that single section. Figures and tables relevant to the information presented are located in such a manner that the reader doesn’t have to flip back and forth between pages when reading and referencing that information. The few references to other sections that I noticed were relevant and necessary (i.e. they point to a section covered in an earlier chapter that presented foundational information important to the topic being discussed). The placement of in-chapter questions at the end of modules is well executed.
The introductory information in the first chapter is well-written and timely. It gives the reader a brief idea of some of the terminology used relating to geologic time and plate tectonics, which are important topics in some of the early chapters.
I would prefer it if the chapter dedicated to plate tectonics (Ch. 10) was earlier in the text, as I feel that information is essential when describing how the various rock types can form. However, the topics can be covered in whatever order the instructor chooses.
I note that there is not a chapter dedicated to mountain building, which is typically present in many other introductory physical geology texts.
I also note that fault types are not covered until the geological structures chapter. Would this information not be more relevant in the earthquakes chapter? It may be a matter of preference, as the information does fit in both places, and I have seen it presented in similar fashion in other physical geology textbooks.
In the print PDF version of the text, all the links visible in the digital PDF version are still present, although the links are static (not clickable). This may be confusing to readers that try and use those links, only to find that they do not function. For the print PDF version, perhaps those could be removed, although that would seem to be a large undertaking, it is realized.
The caption for Figure 13.2.9 (page 428) does not fit in the box around Exercise 13.2. – a minor issue, but worth noting for readability. On page 501, the photos for Exercise 15.2 are partially cut off on the right-hand side.
No errors in spelling or grammar were noticed. The text is written using British English (i.e. metre instead of meter; sulphur instead of sulfur, etc.), which I don’t see as an issue. Other readers might be initially confused, though, if they are not familiar with such spellings of words.
Examples used in the book came from a variety of geographic locations around the world. I didn’t see any issues here.
Please note that this review is for the print PDF version of the newer 2nd edition of this book, published in September 2019.
I feel that this book is well-written, and is definitely worth consideration for anyone looking for a textbook for their introductory physical geology course.

The topics covered in “Physical Geology” by Steven Earle are broad and wide ranging. In looking at the Table of Contents, the book includes 22 chapters that cover all of the topics one would expect in a comprehensive physical geology textbook. In addition, the book includes chapters on climate change, geological resources, the geology of western Canada, and the Solar System. Typically, topics like this are not given their own chapter in introductory geology textbooks but are common in broader based Earth Science books that I am familiar with. While broad in scope, the depth of the individual chapters is somewhat limited and the text seems minimalistic at times. The graphics are generally good and complement the text well, by adding to the depth of the content coverage. This book would probably need to be augmented with additional materials for some topics. However, for other topics such as structural geology, the focus on key fundamental concepts aligns with how structure is typically covered in introductory physical geology courses that I am familiar with. The glossary is reasonably comprehensive in scope and adding the chapter number in which a given term is discussed is a useful feature. The Appendix includes thorough answers to all of the Review Questions and Exercises throughout the book.
Overall, the content accuracy is consistent with modern understanding of geologic concepts. My general test for topical accuracy is based on the author’s description for how magmas form in the context of subduction zones. The descriptions of subduction zone magmatism provided in the Igneous Rocks, Volcanism, and Plate Tectonics chapters are consistent with the generally accepted model for the origin of magmas at subduction zones. The author refers to the asthenosphere as “partially liquid”, which is technically correct, but the text would be improved by emphasizing the ductile nature of the asthenosphere.
The content is up to date and presents topics using modern understanding of geologic concepts, such as in the discussion of subduction zone magmatism. Another good example of contemporary concepts incorporated into the book is the discussion of episodic tremor and slip, which is particularly relevant to students living in the Pacific Northwest. The section on measuring earthquake magnitudes includes various methods, but makes the important point that moment magnitude is now the most commonly used method. The text also briefly discusses using p-waves for early warning systems. The design of the textbook includes a great deal of open page space, which would make it easy to incorporate new content and update portions of the text without changing the pagination.
The text is written in a manner that makes it quite accessible to college students with diverse reading comprehension skills. As mentioned, the glossary provides a good reference for key terms. Also, the abundant figures and graphics throughout the book greatly augment the text.
The text is highly consistent in the use of terminology and framework. Each chapter begins with a list of learning objectives and concludes with a summary. Exercises are included throughout each chapter, giving students an opportunity to work with the content as they encounter it in the text. Each chapter also includes a set of Questions for Review at the end of the chapter, which provides an additional method for students work with the concepts. As mentioned, detailed answers to Exercises and Review Questions are provided in the Appendix.
The book features a high degree of modularity with minimal references to figures etc. outside of a given section. In fact, it appears that one could select any sub-section of the book without having to worry about the text referring to a figure from another section. One of the ways the author achieves this is by providing the same figure multiple times in the textbook, such as for an image depicting the rock cycle. When discussed at the beginning of each chapter dealing with a given rock type or process, the author reminds the reader about the rock cycle and provides the rock cycle figure. At first glance, I was put off by the odd pagination of this book and common occurrence of nearly entire pages of blank, white space. But, it is now clear that this was purposefully done to increase the modularity of this book. I could easily envision reshaping this book into the order that I teach topics in my own introductory physical geology course.
The organization of the book is comparable to most introductory physical geology textbooks with one striking difference. Several of the more recently released textbooks place the chapter on plate tectonics early in the book, before mineral and rocks. This provides a good framework for subsequent chapters. Given the modular nature of Open Textbooks, this organization is not necessary per se, but the author delves into rather involved tectonic discussions in multiple chapters prior to covering plate tectonics in detail in Ch. 10. The author introduces tectonics in Ch. 1, but this is limited in scope compared to the detailed tectonics discussed in the volcanism and metamorphism chapters. I do like the way the author has ordered the chapters with Earth’s interior, followed by chapters on plate tectonics, earthquakes, and structural geology.
The interface was completely free of issues. The book is available in multiple formats, including both a digital PDF and a version of the PDF that is designed for printing. In the digital PDF, high-quality, larger format, higher resolution versions of all of the figures can be accessed by double-clicking on the figure, which opens the figure in a new web-based viewing window. I did not encounter any navigation problems, issues with figures, or distracting display features. The file sizes of the PDF version of the book are somewhat high, but the time needed to download the files was not obtrusive.
No grammatical errors were encountered in reviewing/reading a significant portion of the text. To maintain modularity, it appears that the author has adopted a writing style that is not very “leading”, with minimal transitions from one section to the next.
The text does not appear to be culturally insensitive or offensive in any way. In one example, the author refers to a volcanic eruption 250 years ago at Tseak River Cone that killed 2000 people, according to Nisga'a oral history. These types of examples are scant in the book, as one would expect for an introductory science textbook.
This book represents my first introduction to the world of “Open Textbooks”. At first glance, I was put off by the large amount of white space, with nearly blank pages throughout the book. As I reviewed the book, it became clear that this is a necessary design element to enable sections of the book to be used as separate modules. The other aspect of the book that I do not prefer is the placement of the plate tectonics chapter near the middle of the book (Ch. 10 out of 22). I favor books that place plate tectonics squarely at the beginning of the book and use tectonics as a thematic framework to connect the various topics covered in physical geology courses, especially magmatism, volcanism, metamorphism, earthquakes, and structural geology. However, given the modular nature of “Physical Geology", this qualm could be overcome by reorganizing the materials to match the way an instructor approaches the course.

This textbook covers almost all content found in a traditional physical geology textbook. I actually believe this text is more comprehensive than most introductory texts as it has stand alone chapters on Earth's interior, Geology of the Oceans, Climate Change, and Origin of the Earth and the Solar System. Many introductory texts cram these topics into other chapters and cover them with brevity. Additionally, this text has the most comprehensive coverage of the history of tectonic theory, including a discussion on geosynclinal theory, that I have seen in an introductory textbook. The text also incorporates the quantitative nature of the geosciences more than many other introductory texts.
However, the text does lack a chapter on deserts and eolian processes that is found in many other introductory textbooks.
The table of contents and glossary are both effective, but the text lacks an index. Almost all of the examples and case studies are from western Canada.
The content provided is accurate and I found no significant errors in content or grammar or spelling.
The content is up-to-date and aligns with the content one would read in other introductory textbooks. The authors do a good job of introducing the relevance of each topic in the chapter introductions. The text could be further strengthened by expanding on the importance and relevance the geosciences plays in solving Earth's great environmental challenges.
I appreciate the authors' clear and concise prose and the ability to get to the point. Each chapter begins with a clear set of of learning objectives. A clear and concise summary is provided at the end of each chapter. The authors assume the reader has little to no scientific background, and are able to incorporate aspects of chemistry and physics in a logical manner. I also like that the text does not gloss over the quantitative nature of the geosciences, and provides a variety of examples explained at an appropriate level. Each chapter has numerous embedded exercises that allow students to practice quantitative skills and test themselves on important concepts. These exercises are unique in the sense that they are varied and may appeal to a wide range of learning styles. For instance, in the Minerals chapter, one exercise has the students create paper models of silica tetrahedra and link them together, which may appeal to a kinesthetic learner.
The authors do a decent job of providing a relevant context on why the reader might want to study geosciences in the introduction to each chapter.
Terminology remains consistent throughout the book. Each chapter remains consistent template with learning objectives, text, and end-of-chapter summary.
Each chapter could be assigned individually in a course without too much problem. There are a few instances when a chapter foreshadows what is coming in a later chapter.
The topics are presented in a logical fashion that align with most other textbooks. Plate tectonics, the unifying theory in the geosciences, is introduced in chapter 1, and then treated to a more comprehensive discussion much later in the text. I personally like texts that introduce tectonics early on as it provides context for how minerals, rocks, mountains, etc., form.
The text works great and is easily navigable online. Many of the graphics are small in the online format, but the reader has the ability to click on larger versions. The figures in the print PDF are quite small.
I did not find any grammatical errors in the text.
Unfortunately, the text does not use many examples that are inclusive of races, ethnicity, or backgrounds. Perhaps a future update could include photos of more diverse geoscientists working in the field.
This textbook is comparable to any introductory physical geology textbook. It is more comprehensive than most, and does a good job incorporating the quantitative nature of the geosciences. It is clearly written for a Canadian audience, and most of its examples come from western Canada. The addition of photos showing a more diverse group of geoscientists would be a great improvement.

This book covers most of the fundamental topics that you would expect to find in a regular introductory geology course. The book in its layout is very similar to commercial text that I have used in my classes throughout the years. The index and glossary are easy to follow. I have mentioned few things that I found lacking earlier. I would also like to mention that at Chapter 7 did not mention metamorphic path nor shock metamorphism (and fault-line metamorphism) which are worth mentioning especially shock metamorphism.
In the chapter (1) on minerals and rocks the halite structure is incorrectly displayed. The halite structure is not composed of Na and Cl atoms but of Na cations and chlorine anions. This is an important distinction and should be corrected. In the same chapter the discussion on plate tectonics states that plates are pushed down. That is not the only force - they are also pulled (or sucked) down by gravity due to their density increasing by cooling and melt extraction. In Chapter 3 the section 3.2 the statement equating mantle plumes and hot spots is inaccurate. The hot spot is the result of the plume not the same as the plume. The section in Chapter 8 on isotopic dating is oversimplified and not quite accurate. It is possible correct for initial daughters in a rock (e.g. Rb-Sr dating which is not mentioned). Also there are two U-Pb systems which give rise to the Pb-Pb which should be included. The isotopic dating section is quite weak (e.g. no mention of how radiocarbon works etc.).
The updating will mostly be in planetary research which with its current pace is hard for any textbook to keep up with.
The text is simple and clear and very readable.
Looks pretty consistent.
The divisions into sections and subsections are fine.
The book takes a standardized approach in terms of laying out the material and topics. I would prefer (and I do) to start with the planets then do earth's interior, next seafloor, continental drift and lead up to plate tectonics. Then the chemistry and from there to minerals and then rocks and so on. I guess its more of a systems approach. Few if any of the books I have used in my classes do that. I would also keep the hydrologic cycle and mass wasting with the weathering part.
I had no issues with the interface. The problems I encountered where mostly associated with the upload speed of the book. It would be better to not see every single section and subsection but rather have each chapter separate as such and then simply click on that link or tab to open it to sections and subsections. The pictures are bit slow loading up so that is annoying but perhaps there is a way to have smaller versions (thumbnails) that can be expanded if necessary.
I cannot say if there are no grammatical errors. There is clearly the typical difference in spelling between British English vs. American English.
I do not find the book offensive in any way.
I don't see terms like submarine or subglacial eruptions mentioned in Chapter 4. Also it seems odd to leave out the most common style of eruptions on Earth namely fissure eruptions. Due to the predominance of MOR they must be the most common type of eruption on the planet. Also pillow lava is common in subglacial eruptions not just on the seafloor.

The textbook covers all of the standard Earth science topics in a complete manner. There are even some additional topics such as weather and soil that don't always make it into a standard Earth Science textbook. There are also a lot of Canada-specific parts.
This book is accurate in the information it conveys and there is no evidence (to this reviewer) of any intent to err. Some pictures are too small and therefore may not convey the most precise points.
This book mixes new analyses with older field methods and should continue to be relevant for at least the next 5-10 years. Updates should be easy to insert.
The textbook is very clear and there is little jargon. When jargon does show up, it is never without explanation or lesson.
The textbooks consistency of structure is one of the things that appeals to me about the book. the author put a lot of time and thought into how the themes would be connecting.
This textbook could easily be cut up into its chapters for classroom exercises, but within chapters (like say from 5.2-5.3) are not interchangeable.
The organization is well thought out and ideas and concepts are laid out in a clear and logical fashion.
The interface is great, however many of the figures are too small.
The textbook's grammar appears to be correct.
The text is not culturally insensitive or offensive in any way.

This textbook is very comprehensive, casting a wide net and providing a broad introduction to geology.
Most of the content appears to be accurate; however, there is the occasional issue. For example, in Section 22.4, the author refers the "Manitsoq" [impact] crater. To my knowledge, this structure has not been confirmed as an impact crater by demonstrating that associated rocks have experienced shock metamorphism and therefore is not listed in the Earth Impact Database. Also, I'm a little concerned that many of the figures were taken from Wikipedia, which is not peer-reviewed by experts.
This content is mostly up-to-date and will be relevant for some time to come.
Most of the text is very clear and easy to read, although there are a few instances where the wording is a little odd (example: Chapter 2, paragraph 3) and occasionally goes off on a tangent (ex: Section 22.3, "Pluto's broken heart").
I did not notice any major consistencies
Each chapter and section is well-organized. Sections are relatively short in length and well delineated, making the textbook very modular. The flow between chapters and sections worked very well.
The text was well-organized and the flow between chapters and sections works very well.
I was unable to detect any negative aspects of the textbook interface. In fact, it was very well done and devoid of any technical issues.
I did not detect any grammatical errors.
This is a textbook about rocks, minerals, fossils, landforms, and geologic phenomena and processes, so this question isn't really relevant.
Overall, this is a well done textbook. I would love to see this textbook broaden its base of examples beyond western Canada. I would also suggest that future editions of this textbook rely less on figures/images from Wikipedia.

This textbook covers all the material required for an introductory course in Physical Geology, to a reasonably detailed extent. At times the chapters might seem a little too schematic, lacking some at depth discussion of the topics, and might feel like good summaries of a particular subject. However I do not necessarily see this as a defect, since an instructor can add details in class, and the book still remains a good reference for the students.
I examined only a subset of the chapters, but based on what I read I did not find any errors or mistakes that could affect the usage of the book in a classroom (i.e. mislead or confuse the students). There are indeed parts where simplification is evident, but it’s nothing that an instructor could not clarify and examine in more depth in the class.
Obsolescence should not be much of a problem for a book that deals with well established principles of geology, and indeed I did not find any “old and now debunked” science in the text. Due to its open source nature, updating the book does not seem to be a problem. Again as I pointed out in other parts of this review, the role of the instructor remains important.
The author makes a strong effort to adopt a clear and simple language, to highlight technical terms and to use them in context. This is as expected from an introductory text, and does not seem to require any previous knowledge of the subject. It should be easy for an instructor to help students in particular areas of geology that can be more challenging to the neophyte, and to clarify doubts referencing the textbook.
The book follows a simple and consistent structure throughout, so that the reader will not be confused when going from a chapter to the following. Each chapter starts with a summary introduction, then the main body of the chapter itself, and finally a summary with review questions.
Chapters are not grouped in sections (as one can find in commercial textbooks for instance), however their order is logical (from the viewpoint of an introduction to geology). Since the book is free and modifiable, dividing it in subsections adding more bookmarks, or even reordering some chapters as needed for a class, should not be a overwhelming task.
The logical order of the chapters is similar to what can be found in commercial textbooks, with the added bonus here that everything can be reordered easily to accommodate the needs of a particular class or the teaching plans of a particular instructor.
This is where the book falls short when compared with commercial products, however this is not to be considered as a strong criticism of the final result. Commercial companies have access to resources and time that a writer/publisher who gives away the product for free cannot afford. The final result is still good. Main problems are to be found in the visual support built into the book. The images are always too small, and if a student (or an instructor) wanted to actually print the book, it would be difficult to use them. All the images are live linked, so it is possible to access higher resolution versions, and they seem all hosted on the same site (https://opentextbc.ca), reducing the possibility that those links might become broken. In addition the book is available in an editable format (ODT), and that makes it possible to reformat the whole thing. It would take quite a while though. Moreover the bookmarks of the chapters are in the wrong section (under acknowledgments), but as I noticed before, these can be easily rearranged. All in all navigating the book is easy, at least in the PDF version I examined.
I did not notice any grammatical errors or typos in the chapters I examined.
I confess that I have a hard time thinking of how any of these geologic topics (or geology in general) could be culturally insensitive or offensive. As per the cultural relevance of geology, well it affects the development of civilizations, so this aspect seems to be pretty straightforward to me. However an instructor would have to elaborate on this in a class, especially when dealing with Earth’s resources and their usage.
I was favorably impressed by Dr. Earle's effort to produce a free and overall robust textbook in Physical Geology. The book indeed covers all the topics that are typically presented in an introductory Physical Geology class, and also includes a chapter on the geology of Canada, a welcome addition that can be used as way to illustrate to the students how to connect all the geologic information presented in the course. I would not have any problem in adopting this as the only official textbook for my class (I teach Physical Geology), if I were teaching a face to face and relatively small class. Unfortunately I teach a fully online large (250+ students) class, and I need a textbook with more support for the students. With this I mean that it does need to have a more in depth examination of each topic, and a better high quality visual support. I can of course compensate for that, but only to a certain point. In an online asynchronous class students are supposed to face most of the work by themselves (albeit of course the instructor is always available to help), hence the support textbook has to be as exhaustive as possible. Additional material is offered in the course, along with online video lectures, but still .. an essentially self-contained textbook is – in my opinion – still necessary. The free alternative is possible, but it does require much more effort and time on the part of – already overworked – instructors. For instance commercial textbooks come with material (especially high resolution images) that the instructor of an online (but also face to face) class, can use to create lectures, eliminating the need to start completely from scratch. At the moment I would adopt the book as complementary to my official (and .. yes commercial .. textbook), so that the students could use it as reference (i.e. to review material). On the other hand .. in a face to face small, or relatively small class, there is constant contact (or at least there should be) between the teacher and the students, which should compensate for any shortcomings of the text.

The text covers the areas traditionally covered in an Introductory Physical Geology textbook in sufficient detail. The chapter topics and chapter order is conventional.
Overall, the content is accurate, error-free and unbiased. There are subtle points one could argue over. For example the text states “Where two plates are converging (and the convective flow is downward), one plate will be subducted (pushed down) into the mantle beneath the other.” One could argue that the words “pushed down” could lead to a misconception because, although ridge push is a known plate tectonic force, data suggests that slab pull is greater than ridge push. Another example is that the book ignores the inorganic part of the definition of a mineral. Given the numerous definitions of the word organic, it might not be a bad thing to leave it to upper division classes to discuss this.
The book is relevant in that is covers the fundamentals of introductory geology. Since these fundamentals are well established, particularly at an introductory level, it will have a great deal of longevity. One pet peeve of mine is the relevance of discussing Bowen’s Reaction Series at the introductory level. Almost every textbook includes it and the students dutifully memorize it, without really understanding why. It’s not until students learn igneous petrology, especially the phase equilibria of two-component peritectic and solid solution systems that the gain a real understanding of Bowen’s Reaction Series. I fail to recognize why it should be introduced at the introductory level.
The book is highly readable. While the emphasis is on what we know, it does so in a “easy to read” fashion and doesn’t come across like an encyclopedia. For example, in Chapter 4, the text does a good job on the inter-relationships of magma viscosity and volatile content and their relationship with the potential explosivity of the magma.
The text is both internally and externally consistent. The glossary defines all the geologic terminology used in the text.
Each chapter can be read independently but it does not appear to be readily divisible. For example, section 4.2 starts “As noted in the previous section, the types of magma produced in the various volcanic settings can differ significantly.” Later in the section it reads “First, as we’ve already discussed, felsic magmas tend to be more viscous because they have more silica, and hence more polymerization.” This is already discussed in section 3.2 “These silica chains have the important effect of making the magma more viscous (less runny), and as we’ll see in Chapter 4, magma viscosity has significant implications for volcanic eruptions.” Each chapter in the text has four to six subsections, that should be read in order, I believe they can’t easily be read independently.
The book covers the areas traditionally covered in an Introductory Physical Geology textbook in a common organization. After the introduction, the book begins with earth materials: minerals; rocks; and the rock cycle. One chapter is devoted to geologic time, followed by structural/tectonic aspects of the Earth, including earthquakes. The agents of erosion are next, with the common insertion of groundwater after streams. The text concludes with independent chapters of sea floor geology, earth resources, climate change etc.
I am not aware of any interface issues. Navigation design of images and charts is a small version within the text. When reading the book on-line, clicking on the small image opens up a larger version in the same window – without the image caption. The reader uses the back arrow to go back to the textbook. The student does have the ability to open the image in a new window or tab, you allow simultaneous viewing of the image, image caption and related text. The pdf version I downloaded includes the small images. Clicking on the image in the pdf version triggers a web-browser link to the image.
The text contains no grammatical errors. It uses the British/Canadian spelling of words like colour, dyke and travelling.
The text is not culturally insensitive or offensive in any way. The text is written without mention to race, ethnicity, and background. It does mention the First Nation peoples of Canada mining obsidian as an example of historical resources exploitation. The chapter on Climate Change doesn’t mention how the developed world contributed almost all of the anthropogenic greenhouse gases yet the developing world will suffer the impacts of these gases the most.
The textbook is Canada-centric. Given that almost all the Introductory Physical Geology textbooks published for North America are focused on the United States, this is probably a good thing. Use by faculty teaching in the United States might require some additional examples, perhaps an additional homegrown chapter or two emphasizing local examples when appropriate. Alternatively, this could be a student assignment, using the jig-saw approach.

It is an expansive introductory physical geology text and has a quite a thorough glossary and appendices which include answers to exercises within the chapters and review questions at the end of each chapter.
There are only two areas I feel that could be further developed, deserts and mountain building.
The content is accurate and unbiased. The problems and equations are free of error. The only issue I found was formatting of some chemical formulas and numbers with exponents, but that may be just in certain versions. I reviewed using a downloadable .pdf.
The content is up-to-date and the format looks to be something that can be updated as needed. I found it refreshing there were examples from as recently as 2015, e.g. droughts in California and the New Horizons probe sent to Pluto.
The language used in this textbook is approachable and uses contractions, which I found a refreshing diversion from the traditional writing style of geology texts. The scientific terms were explained in a clear manner. Moreover, I believe most students, even those in the United States, will be able to work with the British spellings and all metric units.
The format of the book and use of terminology is consistent, including the chapter 22 written by Karla Panchuk.
Each chapter has a clear list of learning objectives with sections that are logically ordered. The chapters can be used in-full or instructors can select relative sections. I found chapter 21, Geological History of Western Canada, unnecessary for my use teaching in the United States, but it could be used in institutions in Canada and other regions where a case study of Canada may be of interest.
The organization and flow of the textbook are logical. I do like the introduction to the rock cycle in the first chapter on rock and how it is reference again in subsequent chapters.
The book only has a few formatting issues with exponents and chemical formulas. One can click on the figures to see them larger if needed and then zoom-in further. Also, one can do a simple search to find all relevant terms within the textbook. Many of the figures are well done, including photographs the author took.
There weren't any grammatical errors that stood out when I read the text.
The book included geological examples, most of which were from the author's study area. Some examples were given of other areas in the world.
Physical Geology by Steve Earle is a more than sufficient introductory physical geology textbook that would work well for many community colleges, universities, and online learning institutions. It is a highly economical choice and encompasses much of what is needed for the subject. I would recommend others to take a look at this open textbook as a cost-effective option for students, especially in countries where the cost of tuition makes it difficult for students to afford books. I am an adjunct instructor at a State University, and am interested in using this textbook the next time I teach physical geology lecture.
The text goes into enough detail on all the major Geologic subjects that it would be useful for an overview course. The book's Canada flavor is interesting, however as a U.S. educator, I would be supplementing with more U.S. examples. read more

Topics and their content are very accurate. I did not notice a definite bias in any of the units.
Content is very up to date and that helps immensely when teaching students as they are able to relate material to what they have experienced in their own lifetime. The coverage of the basic concepts make this book able to be used into the future with only minor upgrades as new material comes available.
I think the tone, terminology, and prose are wonderful. One of the hardest things to do is get students to read the material in the book. The material is concentrated and ease to read which should help students get and stay engaged.
The book is very consistent throughout.
The modularity is great. It breaks the material into easy to read sections with lots of illustrations.
Topics are presented well. As an instructor, I know that there is no one starting place for geology. I found the splitting up of the plate tectonics material a little cumbersome, but not unusable.
I did not encounter any issues with the interface. The ability to click on images to expand them is a great help.
I noticed no grammatical issues with the text.
The text uses lots of Canadian examples which is not a huge issue in general. However, here in the states, we would have to supplement with more localized and country specific examples. I noticed no biases with regard to race, ethnicity, or other backgrounds.
This looks like a wonderful text and I would definitely consider it for adoption in my course.

The text is extremely comprehensive in terms of its breadth of general geology topics that would be covered in an introductory geologic textbook. I assume, since the book is designed to address the geology of British Columbia, it covers the main geologic topics that would be important to that particular region. It does an amazing job of covering things such as minerals, rocks, and rock forming environments as they pertain to that region. The chapter on plate tectonics is also extremely informative and gives a very detailed discussion of the history of the science, which is very helpful for students to understand the changes in our understanding of Earth science and how science is a dynamic process. The only holes in the comprehensiveness of the book would be discussion of karst topography, which was very thin, and there was no section on deserts and desert processes. My assumption is that the lack of discussion of these topics is due to the fact that maybe these particular subjects are not found often in the BC area. I would have also liked to see a bit more of a discussion on relative dating, but there is enough information in the geologic dating chapter to cover the topic. Aside from those particulars, the author does a good job tying together anthropogenic issues back to geology in many of the sections which is particularly important for student's ability to identify with the subject.
There is not an index but their is a table of contents that is quite thorough and a glossary at the end. The glossary is not listed by page, however, but is listed by chapter. The author makes it very easy to find these words though as they are well highlighted in the original text of the chapters.
Physical geology is a very accurate textbook. The author has an excellent grasp of the introductory level of geology and presents it in a way that is very accessible. I was impressed at the authors ability to share relevant examples both in his particular area, British Columbia, Canada, and also from other areas of the world as needed.
There were some issues in terms of his discussion of minerals vs. mineral groups and also his discussion of magma vs. lava.
The Physical Geology textbook is very up to date in its science. There were sections that I was surprised to see in the textbook, for instance, there is a discussion of Episodic Tremor and Slip (ETS) in the earthquake section of the book. Also there is great attention given to human's place in the geologic record and our effects of geologic environments. This book will age well because it shares a lot of information about human interaction with the Earth and therefore will remain very relevant as humans become more familiar with their effects on the Earth, a topic that is of particular relevance in sciences today. Also, because the textbook is ordered in sections and is very succinct in its discussion of topics it would be extremely easy to update the text.
I was particularly impressed with the Physical Geology textbook in terms of clarity. The author is succinct in description and uses clear and concise language when describing scientific content. As with all science, there is jargon that is used in the text; however, when jargon is used it is quickly described in lay terms for the student and many times there are diagrams or figures that help to demystify the dialogue. As a result the textbook was extremely accessible. Also, many of the figures directly explain the content discussion and are in line with the text, so you know exactly what figure goes with what dialogue. I find many times with science textbooks there are figures, diagrams, graphs, and tables found all over the page and many times its hard to tie these figures back to the written dialogue without searching for the figure number. However, Physical Geology does not have this problem. I know exactly where to look for the figures described in the text.
Physical Geology is definitely consistent in its terminology and framework. I found that each chapter had the same formatting and, as a result, was very easy to navigate. Also, because the discussion of geologic concepts is not generally linear (for instance its really hard to understand the formation of rocks without understanding minerals and to understand both you need some understanding of plate tectonics), the textbook had a way of quickly discussing topics necessary for understanding before fully delving into the topic in its own particular chapter. For instance, in chapter 1 there is a quick synopsis of plate tectonics before chapter 10 where plate tectonics is fully discussed. This is extremely helpful for the discussion of rocks and minerals which comes in chapters 2 through 7. The author also does this with climate change, he gives students the necessary, relevant information about the topic needed in certain chapters before the topic is thoroughly discussed in its own chapter. I find that when I teach I often do the same thing, leaving breadcrumbs of information about topics when needed before delving deeply into the subject.
The framework of this book lends itself easily to modularity. Each chapter is broken down into subheadings that can be used separately from the whole of the chapter. This books could easily be used in other classes and out of specific order because it is well organized.
Physical Geology has a structure that allows the book to be broken up and reproduced into major sections and subsections and so the actual organization of topics is not necessarily an issue for teachers, but I would not say that the order of the chapters is particularly logical. The beginning of the textbook's chapters has more logic to it, minerals, then rock and rock forming processes, but after chapter 7 the flow of content becomes a little mixed. For instance the book goes from plate tectonics, to earthquakes, to structures, to streams and floods. But again, they way that the book is assigned by the teacher makes the chapter order obsolete.
What is very nice about the textbook is that each chapter starts with learning objectives, follows with descriptive text to explain the learning objective, then many of the subheadings end with an activity or exercise that the student can do to better grasp the content, and at the end of every chapter there is a summary of the topics discussed and questions for review. Also, each exercise and review question has answers in appendices in the back of the book. Those extra exercises and review questions makes the use of this book even more enticing.
Lastly, there was one chapter that I really did not understand the order of and that was the chapter on earthquakes (chapter 11). The chapter starts basically by talking about rupture surface, then aftershocks, then ETS events, and then throws in a huge discussion about where we see earthquake on plate boundaries but, almost as an afterthought, discusses things like focus, epicenter, and the waves created by earthquakes which seismologists use to measure the magnitude and intensity. In my mind those particulars are much more important for student understanding than ETS events.
The interface of the book is just fine. All of the images and charts seem to be in order. The only issues I saw were in the beginning of the book and were mainly issues in the formatting of lists with indentation issues in the review questions and exercises. These formatting issues distract in so much as they are noticed but I don't think they affect the readability or usability of the text.
I did not notice any grammatical errors.
Physical Geology is a science text and therefore pays little attention to culture, per se. There is discussion of human interaction with the Earth, and a bit about First Nations, but that's about as much as is discussed in the book.
This textbook is quite useful for teachers who would like a simple textbook with easily understood content, accessible formatting, and exercises and review questions that supplement student understanding. It's best fit would be for a 100 level, non-major class where students interaction with the geologic content is mainly surficial. The regionality of the examples would also make it necessary for teachers using the textbook to have supplemental information from their locality or notable international examples at the ready so that students can identify better with the content of the book, but most teachers already have these types of examples in their own lectures.

The book covers all of the topics typically covered in a short introductory physical geology textbook. Some topics are covered more thoroughly than others. For example, plate tectonics is covered in some depth, and includes a section (10.2 - geosynclinal theory) that would be omitted from almost any other introductory textbook. On the other hand, the topic of mass wasting mitigation would have benefited from a description of the various mitigation strategies (e.g., rock bolts, avalanche chutes) and how they work. As a U.S.-based instructor, the focus on western Canadian geology meant that examples were less relevant to my students. The one place this is a major problem is soil classification. The chapter on soils of Canada makes it clear that Canada uses a different classification system from the U.S.
Overall, the book is highly accurate. There is one unfortunate typo where the plural of tetrahedron is defined as tetrahedral. It is correctly spelled tetrahedra everywhere else. Almost all introductory-level books make simplifications (and oversimplifications) that can be perceived as incorrect by experts in the field, but don't have a negative impact on student learning. For instance, it is stated more than once in chapter 22 that the abundance of material available for building a planet is a function of distance from the sun. That's not strictly correct. The density of the pre-solar nebula (gas+solid) drops off with distance from the sun, but the percentage of the nebula that is solid (as opposed to gas) increases with distance. These two opposing factors mean that the largest amount of solids available for planet building occurs at Jupiter's location. Is this important for an introductory student? Not really. Neither is knowing that "amphibole" is a mineral structure, rather than a specific mineral. The only place that oversimplification made me unhappy was the description of the asthenosphere and D" layers as "partially liquid". I find that students imagine big pools of magma in the asthenosphere. I prefer really soft plastic solid containing very minor amounts of dispersed melt.
The content of the book is up to date. Most concepts are not likely to need any revision in the near future.
The book is written in fairly simple language appropriate for a freshman level text. As it was written for a Canadian audience, it contains spellings (e.g., metres, centre) that would give my U.S. based students pause. The only place this might cause problems is "dyke: for dike.
The book appears to be highly consistent in terminology and framework
The book is neither more nor less modular than any in print short introductory textbook. A chapter is more or less a self-contained unite (e.g., chapter 12 on structures, chapter 13 on streams).
The topics in the text are presented in an order similar to most introductory geology textbooks: minerals and rocks --> plate tectonics --> earthquakes and structures --> surface problems, with resources and planetary geology tucked onto the end.
I downloaded the book to my Nook reader. Many, if not most, of the illustrations were too small for me to see any detail, and were pixelated/blurry when I tried to enlarge them.
The text looked fine to me.
The text is not culturally offensive. It is clearly meant for Canadian students rather than U.S. based students. It was difficult to see the images (see #8), but the few people in the images all appeared to be of northern European ancestry. Not much in the way of diversity.
The book does a nice job explaining two concepts (isostasy, plastic solids) that trip up many beginning students. I liked the thin section views of sedimentary rocks and quartzite, and wished that similar views of igneous rocks and foliated metamorphic rocks had been included.

This text is comprehensive - it thoroughly covers all the topics of a typical introductory geology class, and the index and glossary are useful.
The content seems accurate. I didn't find any serious errors in the content. There are a few formatting oddities (esp. with figures and tables) that could be improved. The text is a bit biased in that it's western-Canada focused (this isn't necessarily a bad thing).
Regarding content, the text is up-to-date but should be relevant for a long time. Given the pace of the relevant processes, geology texts can be useful for a long time. Regarding presentation, I think this text may not be designed for long-term use as texts (and courses) become more and more digital. This text is basically the same as any other intro geology text, that happens to freely available online. But I think "modern" textbooks need to be more than a collection of words and graphics - we need the ability to navigate without scrolling through digital "pages", links to relevant animations, discussions by experts, interactive study-aids, youtube examples, etc., etc., etc.
The written text is clear and appropriate for the course level. One comment about the graphics: Make them bigger! Many of the photos and cartoons are too small. I'd also suggest wrapping the text around the graphics so as to make them a more integral part of the text.
The best intro geology text i've seen/used is Exploring Geology, by Reynolds et al. The emphasis there is graphics - the text accompanies the graphics (not the other way around which is the standard).
The book is consistent from one section to another in terms of appropriateness for the audience, and presentation. I would suggest to make the section headers (which are boldfaced) bigger - they often get somewhat visually lost stuck between graphics or big blocks of text.
There is some inherent overlap of content in this field, but the book handles that as best as you can, and could be divided up (by chapter?) without too much trouble.
The book is organized well and flows from one topic to another adequately. [Aside: I think it's more logical to present plate tectonics as early as possible, but i understand the reasoning to do earth materials first too]. Some of the blue "Exercises" boxes formatting is strange and I can't figure out what they are for.
I didn't see any major problems with the interface (I am using a .pdf). Some of the blue boxes don't align vertically with the other blue boxes. The images and charts are too small, but are readable (but may cause accessibility issues).
I didn't find any grammatical errors. There were a few places where I may have phrased things differently, but that's just based on preference.
This isn't terribly relevant to a geology text, but the it was culturally relevant (especially if you are in western Canada).
Writing and assembling a text is a major effort and I applaud the author for doing so, and making it freely available. We need more people like to you!

The text is comprehensive and does cover all topic areas typically covered in a physical geology course. Further, the text includes a glossary.
From the material I have sampled I have not discovered any inaccuracies. And discussions of the major topic areas are consistent with those typically found in the mainstream physical geology texts.
Content is indeed up-to-date with discussions of the most recent developments in the field, and obsolescence in the field of physical geology is not a significant issue. Moreover, because of the structure of the text, updating it should not be challenging.
One of the strong suits of the text is it's clarity. It's written with an economy of words and in particular jargon. Sentences are written in a short, to the point fashion, and that's desirable.
The text consistent in terms of it's structure. Each chapter starts off with an Introduction, which includes "Learning Objectives," followed by the "Body" of the chapter -- which includes figures and exercises. Each chapter concludes with a "Summary" and "Questions for Review."
It's very easy to pick and choose topic areas in the text, because of how the text is structures. Later material in the text does of course, to a certain extent, build on earlier chapters -- but if one is careful to assign earlier foundational material -- it is easy to reorder the sequence of chapters (topics) presented.
The organization/structure/flow of the text is fine and is quite similar to that of mainstream physical geology texts.
There are no issues whatsoever with navigating through the text, with either the basic text or with figures and exercises.
Grammar is correct and standard.
I found no instances of cultural insensitivity or offensive references/language, etc. in any fashion.
I am on the whole impressed with the text. It's clearly written and accurate. My only negative comment has to do with the artwork. I am used to the more "sophisticated" art presented in say, Pearson's geology and geography texts, so the simplicity of the art in Earle's text will take some getting used to. But in a way the simplicity may be a plus, as it keeps things "simple" for the students.
I am considering adopting the text for my future physical geology/geography courses.

The book covers everything one would normally look for in an Introductory Physical Geology (IPG) text, including "ocean geology" and Earth/Solar System (chapter 22...which in the index has the odd property of having the same guest author mentioned after every section). Some of the chapters can be rated as rather short, and thus lacking detail that other IPG texts do have, but this makes the book (conservatively) a few hundred pages shorter than many IPG books, and probably puts it closer to the shortest of the for-profit texts.
There are errors and oversimplifications that are not hard to find. Chapter 1: "A mineral is a pure substance with
a specific composition and structure, while a rock is typically a mixture of several different minerals (although a
few types of rock may include only one type of mineral). Examples of minerals are feldspar, quartz, mica, halite,
calcite, and amphibole." Minerals are far from "pure substances" (whatever that means), and feldspar, mica, and amphiboles are not minerals, they're families of minerals (some 130 amphiboles). Section 1.6, Ma and [sic] ka is defined differently than in the glossary. The definition of a mineral is an oversimplification. Olivine is described as a mineral (it's not). What's universally described as the Si-O tetrahedron is described in the book as a "silica tetrahedron". "Tetrahedral" is not the plural of tetrahedron. Hurricanes Sandy and Katrina are held up as examples of storms somehow connected to "climate warming" which ignores that (a) there's zero evidence connecting those particular storms to "climate warming", (b) geologists had long predicted New Orleans was going to be hit by a hurricane, and (c) Sandy was a large but weak storm and much of the prodigious damage was a result of building in recent decades in highly vulnerable areas. While the general flow is similar to other IPG texts, and much IS accurate, one starts to anticipate the next not-quite accurate statement, which is uncomfortable.
Most of the text appears relevant and timely, though of course a good IPG text should mostly focus on very well-established aspects of geology that are not likely to change. The linearity of the text (text...usually straightforward figures with concise captions...more text...repeat) is similar to texts of decades past, which is a relaxing and easy-to-take-in presentation in great contrast to some of the current "deluge of figures" style IPG texts that few if any students can learn from. This linearity makes updating and improving easy.
The text is written in basic, clear language. I compared it using standard reading-clarity tests (volcanology and mineralogy chapters) to most other IPG texts, and it rated among the very easiest to read, at (varying with the test) grade levels from about 9-12. The reader of this information can decide whether this is a pro or con. On the pro-side, the wording is very simple, as shown by the fewest syllables per word and letters per word of almost any other IPG books, and if one comes down on the side of making our science texts more tractable for non-science majors, this is probably a good thing. If one comes down on the side that simplifying our writing to match the decreasing reading skills and concentration skills of our students, perhaps this is a bad thing.
Around a dozen terms from the glossary were selected and looked at their presence and order within the book, especially, looking for words used before they were defined. The words I picked were used an average of 4 times (not counting the glossary), typically where first defined, again in the text, in a figure & caption, and often later in a secondary usage. Other than issues with incomplete or oversimplified definitions, consistency seemed adequate.
Compared to other IPG texts, the book is less modular, i.e., the sections (20.1, 20.2, etc.) are longer. To some, this is rather nice, rather than the staccato style subdivisions of some IPG books. It's up to the instructor to decide if this is in the best interest of the students. Partly, the presence of fewer subdivisions is based on the choice of topics. There's plenty of material here to fill any normal IPG course, but it's likely that specialists will find that some of their favorite topics are not covered in their go-to chapters. E.g., chapter 20 is some 25 pages long, but there are only four subdivisions. Thus, for the instructor that likes to micromanage, it's likely going to be hard to choose sections to omit.
The organization is very standard for IPG texts. The only two issues are the placement of the tectonics chapter, which is important to many instructors: it's chapter 10, although there are mentions of tectonics earlier. Another issue is the placement of the Earth/solar system chapter--dead last. This is indeed one way of doing it--now that we're done discussing the Earth, let's look out at the rest of the solar system. However, a major part of the chapter is the origin of the Earth, the Big Bang, and planetary formation, which suggests it could be better placed early in the book. Two chapters some might miss are those on historical geology (although there's a chapter on the geological history of western Canada [why not expand this to western N. America?]) and scientific thinking.
As mentioned above, there's a soothing simplicity to the PDF, simply text...figure...text. Links in the table of contents jumped quickly to the correct location in the book. All the figures I checked quickly opened (in my case, on my second monitor), but without the figure caption. Thus, the reader does need to go back and forth between the figure in one place/monitor and the caption in another place/monitor. The size and resolution of especially the photographs was not standard--some were no larger than on the PDF. However, note this--at 100% magnification on a large monitor, many figures were not at all clear UNLESS 'popped out'. It's unclear why they are not inserted larger, unless to keep the size of the PDF (over 100 MB) down. No other problems encountered.
Few grammatical errors noticed. Generally simple wording, short sentences, straightforward writing.
None noticed; not much of an issue in general in geology.
As quickly evident from the preface and early in the book, based on the genesis, authors, and initial purpose of the book, there is a heavy bias toward Canada and especially B.C. This doesn't necessarily mean that, e.g., the photos were inferior, but some very familiar international examples were clearly omitted. This does make the book feel more regional.
Many IPG texts pose unrealistically complex questions or tasks for students that few non-science IPG students would be interested in. One good thing about this book is that many of the exercises are not like that; they get the student to think or do something that is nicely connected to the material without being excessively demanding. Realistically, it's an accomplishment to get many students simply to read the assigned chapters; to get them to do/think a little extra is a good bonus.

This book is comparable in scope to the priced books I have and am currently using. I was very pleased to find a book I could use for my Earth Science course that touches on the same topics I use in my class that is obviously affordable to my students.
Chapter 1 provides a summary introduction for the rest of the book which carries the reader through the foundations of geologic principles, ending with an introduction to the Earth's place in the universe. Physical Geology covers every topic an Earth Science class would cover with the exception of specifically weather and climate. However, Chapter 19 deals with the properties of weather and climate with enough detail within the context of climate change.
The lack of a weather and climate section is understandable as the book is focused on geology- climate change being in part a byproduct of geologic work in drilling and mining, and natural processes. Any further information on weather processes may be supplemented from other open sources. Overall, this book is very comprehensive for a semester course in earth science or physical geology.
I did not see any errors, inaccurate statements or evidence of bias.
Science is a relatively slow process with new ideas and discoveries filtered into textbooks over time. The book Physical Geology as it stands should have a long shelf life as far as knowledge content. Due to the layout of the chapters, the book can easily be updated as needed with new concepts with little disruption to the flow of the prose.
However, this book uses many URLs as citation links, or links to supplementary information, including larger images. These links will need to be tested periodically to ensure the book is not broken. Though useful for a thumbprint, I tend to shy away from Wikipedia links only because anyone can edit the Wiki content.
As an introduction to Earth Science text, the book is fairly balanced in the use of technical jargon. The basics are laid out clearly, in plain terms and the descriptions tend to ramp up introducing the students to new terminology. The technical terms are bold and clearly put into context, or defined directly in the text. A student should have no problem navigating the text. The use of end of chapter questions and exploratory experiments students may conduct on their own help drive home important concepts.
The text is well put together. Chapter one introduces the reader to the field of geology and the foundational theories and principles for geologic research. This sets the stage for the rest of the book. Though I don't use them in my lectures, each chapter sets out learning objectives which some students may find helpful. The chapters are broken into smaller sections and end with study questions that give students the chance review their knowledge of the topics.
This book, while it is presented in a logical order as it stands, it is very easy to divide into smaller sections each with headings and subheadings to facilitate navigation. The instructor can easily rearrange the readings without losing meaning or context.
The book was well organized and touched on topics I find important in my class. Where necessary, new sections built on knowledge in previous sections. Overall the book was laid out in a logical and manageable fashion for someone who wishes to use the book from cover to cover in the order it is presented.
The linked table of contents in the PDF version I am reviewing was extremely helpful in navigating the book and works well. The HTML version also contains hyperlinked table of contents. This form of navigation is helpful when one navigates away from an online PDF version only to return to the title page of the PDF.
Several images are blurry or too small to make out clearly in the PDF version of the textbook. Clicking on an image will take the reader to an online version of the image, however this would not be possible without internet access. Some images could be enlarged to better fit the page as well. Many of the tables are formatted across multiple pages making reading difficult. Photo and illustrations labels are not consistently spaced. These are easily remedied however with sharper images. There are no issues with the text layout aside from what is pushed around by some of the images and tables which leave mostly blank pages. These are the only issues I find with the book's interface. The graphics and table layout is the only big hit this book takes.
No grammatical errors were noticeable.
I could not think of a way an earth science or geology textbook could be culturally insensitive until I realized the author did a great job mentioning native groups and the names they used for geological locations. There is no reason I can see that anyone would take offence with the content of the book.
I teach my earth science course from a historical perspective, getting across how we know as much as what we know. This book provides very adequate content on the historical reasoning behind the discoveries. While it lacks a robust weather and climate chapter, that is remedied by supplementing the text with readings from other open sources- either textbooks or government agencies.
I always start my course out with a sample of astronomy, so I was pleased to see an introduction to the Earth's place in the universe at Chapter 22. The modular nature of the book lends itself to reading out of order so I can easily work this textbook into my course.
