The study of fossils, minerals, and gems has played crucial roles in increasing our knowledge about the Earth, the changes the planet has gone through, and the species that have inhabited it. This volume introduces the fascinating disciplines of geology, paleontology, and mineralogy, and how they reveal secrets of the Earth's history. Coverage includes: a systematic treatment of Earth history, rock types, marine fossils, terrestrial fossils, crystals, gems, and precious metals that provide insights into Earth's character; the most current data available on such topics as global tectonics and faunal extinctions, including a wealth of information about the demise of dinosaurs; new technologies in detecting and preserving rocks and minerals; and the effects of erosion and climate changes.
