Physical Geology
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.
