CAVES - 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, and grottos.
We ask you to please donate to the Big MaMa Earth Learning Academy an environmental solution based non-profit. Your donations will be utilized for continuing education about “Caves” and other important issues.
