Geology is the study of Earth. Modern geology includes studies in seismology (earthquake studies), volcanology, energy resources exploration and development, tectonics (structural and mountain building studies), hydrology and hydrogeology (water-resources studies), geologic mapping, economic geology (e.g., mining), paleontology (ancient life studies), soil science, historical geology and stratigraphy, geological archaeology, glaciology, modern and ancient climate and ocean studies, atmospheric sciences, planetary geology, engineering geology, and many other subfields.
Geologists study mountains, valleys, plains, sea floors, minerals, rocks, fossils, and the processes that create and destroy each of these. Geology consists of two broad categories of study. Physical geology studies Earth’s materials: erosion, volcanism, and sediment deposition that create and destroy the materials and landforms. Historical geology explores the development of life...Read more
