The Living Earth series will be an indispensable resource for students and generál readers who are just beginning their study of the Earth or for more advanced researchers seeking in-depth information. Jon Erickson has written several books on Earth science and geology. After serving in the U.S. Navy, he attended Arkansas Polytechnic College (receiving a B.S. degree in physical science) and the University of Arkansas (earning an M.S. degree in natural science). He has worked as a geologist for major oil and mining companies and as an engineer for aerospace and electronics companies. Mr. Erickson resides in western Colorado and is currently an independent geologist. Other volumes in the Living Earth series include An Introduction to Fossils and Minerals: Seeking Clues to the Earth's Past, Revised Edition; Making of the Earth: Geologic Forces That Shape Our Planet; Plate Tectonics: Unraveling the Mysteries of the Earth; Rock Formations and Unusual Geologic Structures: Exploring the Earth's Surface, Revised Edition; and Quakes, Eruptions, and Other Geologic Cataclysms; Revealing the Earth's Hazards, Revised Edition.
