The Critical Zone

Summary and Final Tasks


Geology, the study of Earth, is a broad and complex discipline. In this lesson, you reviewed some geologic concepts, including the difference between the three basic rock types. You read briefly on plate tectonics, geologic time, the rock cycle, and various related processes focusing on weathering, erosion, and deposition. I asked you to consider several questions regarding the role of parent material, erosion, and deposition on soil formation. Finally, various types of geologic maps were explored—the accessibility and usefulness of these resources are the most important lesson for you to draw here.
