I bought this study guide to help me in my geology class. It isn't the same edition as my textbook but it is still the same. The chapters are the same and it has really helped me remember the material. The pages have fill in the blank and multiple choice and practice quizzes. All the answers are at the end of the book. I recomend this for anyone who is taking geology and is using the "Earth" book.

Despite the proliferation of introductory physical geology textbooks in recent years, none have surpassed the quality of Tarbuck and Lutgens' "Earth". The text is accurate, up-to-date, well-organized, and exceptionally lucid. The writing flows nicely and presents complex topics and ideas in a way that is easy for non-scientists to understand, while at the same time resisting the trend toward "dumbing-down" that has recently affected many introductory textbooks in Earth sciences. The book is also illustrated wonderfully with diagrams that are effectively designed, beautifully executed, and perfectly matched to the accompanying text. The photographs are likewise outstanding in subject and quality, with great efforts obviously having been made to find excellent pictures that complement the text and clearly illustrate the features and processes being described. The overall quality of the photographs is far better than in most other textbooks of this kind. Substantial improvements have been made for the sixth edition, including the addition of helpful illustrations to the glossary and the addition of many new photographs throughout the book (for example, compare the 5th and 6th edition pictures of drumlins, moraines, igneous rock textures, tsunamis, sinkholes, etc.). After examining many textbooks, I have decided to use this one in the undergraduate course I will teach next year.

This book has dozens of errors, but in its defense, I must say that every introductory textbook I've used or reviewed has similar errors. For example, thermal expansion due to daily temperature fluctuations does NOT fracture rocks. Fire fractures rocks, and local fires can occur in many deserts. The photo of a rock split is actually due to ice (not frost) wedging. Deserts can be freezing. The book does not address the importance of past climates. Most of North America's landforms were formed under wet, warm climates, not today's. The hydrologic cycle should be expanded to the geohydrologic cycle, which incorporates plate tectonics. Plate tectonics, as presented, is rather primitive. We're in, I'd say, 3rd generation plate tectonics, but it is not being taught. Mountain glacial landscapes are entirely misinterpreted, based on a false paradigm originating in the 1840s. Yosemite Valley is far more a relict tropical landscape than a glaciated one, and Bridalveil Falls has existed for 10s of millions of years before glaciation. Evolution of desert landscapes is equally as bad. The authors don't understand pediments, which are exhumed weathering fronts (as in Joshua Tree National Park) or exhumed detachments (as in the Mojave Desert). Etc., etc.
