Geology tries to explain how the Earth was formed and how it changes. Scientists called geologists study rocks, soils, mountains, rivers, oceans, caves, and other parts of the Earth. The word geology comes from Greek words meaning Earth and discussion. Fossils help people learn how life on Earth developed. Physical geology is the study of the materials that make up the Earth, and the forces that shape the Earth.
Historical geology deals with the history of the Earth.
Many problems are a part of both fields, and physical and historical geology are usually studied together. We'd like to hear from you. Click here to submit your comments.
