Karst is landscape formed from the weathering of limestone. Limestone is a sedimentary rock created from the remains of dead sea creatures and is predominately made up of calcium carbonate.

Limestone | Minerals Education Coalition

Limestone. Limestone is a sedimentary rock composed mostly of the mineral calcite and comprising about 15% of the Earth's sedimentary crust. It is a basic building block of the construction industry (dimension stone) and a chief material from which aggregate, cement, lime and building stone are made. 71% of all crushed stone produced in the U.S. is either limestone or dolomite.

Presently, limestone products are used as a crucial part in most industrial processes.

How caves form | Caves and karst | Foundations of the Mendips

The streams reappear at the base of the limestone outcrop at large springs, for example at Cheddar and Wookey Hole. Over time, the water finds new lower routes leaving some caves high and dry. Some of these have been dug out by cavers. The dipping Carboniferous limestones have produced a particular style of cave.

Limestone: The Calcium Carbonate Chemical Sedimentary Rock

Limestone, as used by the minerals industry, is any rock composed mostly of calcium carbonate (CaCO 3).
