Geology is the study of the earth, its materials, and the processes acting upon them. It includes the study of rocks and minerals; and their formation, weathering, and metamorphosis. So, when you need an answer to a question about rivers, mountains, volcanoes, rock cycles, plate tectonics, or other geological aspects, our Geology category is the place to ask it.
