A cave or cavern is a natural underground space large enough for a human to enter. Caves are produced naturally in the environment by the weathering of rock and they often extend deep underground. The word cave can also refer to much smaller openings which occur in the environment such as sea caves, rock shelters, and grottos.
Speleology is the science of exploration and study of all aspects of caves and the environment which surrounds the caves. Exploring a cave for recreation or science may be called caving, potholing, or, in Canada and the United States, spelunking ..
