Description Of Cave:

A cave or cavern is a natural underground space large enough for a human to enter. Caves form naturally by the weathering of rock and they often extend deep underground. The word "cave" can also refer to much smaller openings such as sea caves, rock shelters, andgrottos.

Caves are found throughout the world but only a portion of them have been explored and documented by cavers. The distribution of documented cave systems is widely skewed toward countries where caving has been popular for many years (such as France, Italy, Australia, the UK, the United States, and so on.). This is a great generalization as large expanses of North America and Asia contain no documented caves where as areas such as the Madagascar dry deciduous forests and parts of Brazil contain many documented caves. As the world’s expanses of soluble bedrock are researched by cavers.The distribution of documented caves is likely to shift. For example, China, despite containing around half the world's exposed limestone .More than 1,000,000 square kilometres has relatively few documented caves.
