Cave

Caves and caverns are natural voids under the surface of the Earth and have also been observed in other rocky worlds. Caves often form by the weathering of rock and can extend deep underground. Exogene caves are smaller openings that extend a relatively short distance underground.

Caves which extend farther underground than the opening is wide are called endogene caves.
