摘要

Earlier editions (sixth was 1992) were entitled The Earth's Dynamic Systems: A Textbook in Physical Geology. A highly colorful, introductory textbook for freshmen at both two- and four-year schools. The core theme centers on the two major energy systems that make Earth a dynamic planet: the hydrologic system and the tectonic system. This revised and updated edition has improved illustrations throughout, and uses recent space photographs and new computer-generated physiographic maps to introduce the chapters.
