THE CHANGING EARTH: EXPLORING GEOLOGY AND EVOLUTION, is a leader in the Introductory Geology course. Three interrelated themes (plate tectonics, organic evolution, and geologic time) help you understand that Earth is a complex, integrated, and continually changing system. In the new edition authors James S. Monroe and Reed Wicander integrate new content emphasizing the economic impacts of geology. Topics such as fracking, nuclear waste, and the threat of earthquakes are covered in new Geo-Impact boxes that stress real-world applications. Lauded for their clear writing style, the authors go beyond simply explaining geology and its processes; rather, they place that knowledge within the context of human experience by consistently emphasizing relevance, resources, and the environment.
