This innovative workbook contains readings, questions, and exercises that will cultivate through active learning and inquiry, a greater appreciation for the Earth system and its inhabitants, and demonstrate how relevant Earth Science is to our lives and communities. Five recurring themes—interactions of spheres, scale, cycles, energy, humans and the earth system—are woven throughout the five modules: Introduction to the Earth System, Geosphere, Hydrosphere, Atmosphere, and Cosmosphere. An Explorer's Guide is written to accompany Earth Science, 10/e, and the close integration makes it easy to incorporate into existing courses.
