Geology
Do you ever wonder why one river is straight and flows quickly while another meanders along curves and seems to be slow and peaceful, or how the mountains were formed? 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.
