Essentials of Geology: Portrait of Earth

Rating:
Summary: Very readable, logical sequencing, great illustrations, fun.
Review: This is the third of the textbook type of geology books which I have tried, and it is by far superior to the other two (both of which are very popular and well known.) The problem with the other two is that they begin discussing rock types before discussing plate tectonics and the forces which create and change rocks. Thus, much reference is made to concepts which were never introduced. Marshak does it correctly. He starts with plate tectonics and thereby he introduces the concepts necessary to understand the other dynamic forces at work on Earth. His explanations are complete, well presented and easy to follow. They are accompanied by illustrations which are not only very clear, but esthetically very pleasing to look at. I am glad I found this book. It is a pleasure to read, is very informative, and a welcome change from its more frustrating peers. I highly recommend Essentials of Geology by Stephen Marshak.
