Cave Lake

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.

Lake

A lake is often a naturally occurring, relatively large and fixed body of water on or near the Earth's surface. It is localized in a basin or interconnected basins surrounded by dry land. Lakes lie completely on land and are separate from the ocean, although they may be connected with the ocean by outflowing rivers. Lakes, like other bodies of water, are part of the water cycle, the processes by which water moves around the Earth. Most lakes are fresh water and account for almost all the world's surface freshwater, but some are salt lakes with salinities even higher than that of seawater. Lakes vary significantly in surface area and volume of water, but in total cover approximately 2.5 × 106 km2 (less than 2%) of the Earth's surface.
