Geological sinkhole
Sinkholes are a naturally occurring geological feature that is common in Florida. Much of our state sits on a bedrock of carbonate rock, primarily made of highly porous limestone. As water dissolves the limestone, it creates cracks and holes in the stone. The soil above then seeps down causing a pit to form.Karst is a generic term that refers to the characteristic terrain produced by erosional processes associated with the chemical weathering and dissolution of limestone or dolomite, the two most common carbonate rocks in Florida. Dissolution of carbonate rocks begins when they are exposed to acidic water.
