The introductory geology course is a forum where students learn about the scientific underpinnings of geology and how those apply to their roles as critical thinkers and decision makers. Physical Geology: The Science of Earth is a flexible learning tool that equips students with assets and content necessary to understand our planet and the science that drives it. By combining traditional introductory content with unique topics and innovative pedagogy, author Chip Fletcher challenges students to think critically about physical geology and its impact on their lives and the planet.
