内容説明
Get a rock-solid grasp on geology
Geology For Dummies is ideal reading for anyonewith an interest in the fundamental concepts of geology, whether they're lifelong learners with a fascination for the subject or college students interested in pursuing geology or earth sciences.
Presented in a straightforward, trusted format-and tracking to a typical introductory geology course at the college level-this book features a thorough introduction to the study of earth, its materials, and its processes.
Rock records and geologic time
Large-scale motion of tectonic plates
Matter, minerals, and rocks
The geological processes on earth's surface
