Surveying the basic topics of physical geology, this text is written in straighforward, non-technical language for the benefit of students with little or no college-level science experience. The text provides a sense of the observational techniques and reasoning processes, which foster a basic understanding of physical geology. A cornerstone of previous editions of Earth has been its art program. This edition includes a thoroughly revised and expanded selection of colour photographs and line art, including more than 200 new or redrawn illustrations by Dennis Tasa and Tasa Graphics, Inc.
