This introduction is an all-encompassing look at the Earth: how it was formed and how it works. It explores the emerging geological research and explains how new advances in the understanding of plate tectonics, seismology, and satellite imagery have enabled us to begin to see the Earth for what it is, a dynamic and ever changing planet. It introduces the concepts of plate tectonics, continental drift, the earth's structure, and sea-floor spreading.
Our review: "When I came across this little book for the first time in Bookshop Santa Cruz I almost paid full retail for it! I did go straight to the shop and order a bunch of copies. I'm not disappointed. Earth : A Very Short Introduction has become an instant favorite and one of my must have recommendations. Here's a little pocket size book that you can carry with you just about anywhere. It has great coverage of the principles of geology and is presented in a narrative style. This is a fun read, not a dry geological text."
A new book for 2010 which will lead you to twenty-seven sites that show off the geology of Yosemite National Park. Turn your trip into much more than just a tour of the fabulous scenery. You'll see all those gorgeous sites but you'll also learn about how the domes such as Half Dome are formed, how Yosemite Valley, and much of the park, was carved by glaciers, about the continued shaping of the park, Volcanoes, hanging waterfalls and more.
The book is heavily illustrated with color photos and illustrations. The geology behind the park is presented in an easy to read and understand text. Read the story behind the geology.
