An outcrop is a natural exposure of rock or other geologic formation that protrudes from the surrounding landscape. Outcrops can be found on mountains, hills, cliffs, and other types of terrain. They can be small or large, and can vary significantly in shape and composition. Outcrops can be formed by a variety of processes, including erosion, faulting, and volcanic activity. They are often studied by geologists and other scientists to gain insight into the geological history of an area.
