The Formation of Stalactites and Stalagmites HowStuffWorks

Limestone caves where most stalactites and stalagmites are found are mainly composed of calcite a common mineral found in sedimentary rocks Calcite molecules are made of calcium and carbonate ions and are referred to as CaCO 3 or calcium carbonate When rainwater falls over a cave and trickles through rocks it picks up carbon dioxide and...
