OverviewTHE CHANGING EARTH: EXPLORING GEOLOGY AND EVOLUTION, Seventh Edition, is a member of a rare breed of texts written specifically for courses covering both physical and historical geology. Three interrelated themes (plate tectonics, organic evolution, and geologic time) help students 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. New Global Geosciences Watch activities help students learn how to use an extensive database of articles on geology that are updated several times a day and are available exclusively for users of this book.
