What is Calcium Carbonate? - Industrial Minerals …
The calcium carbonate water runs down and eventually reaches an air-filled cavity underground where the carbon dioxide can be released. When it is released, the calcium carbonate crystallizes again. Stalactite and stalagmite formations are created when water containing calcium carbonate drips, leaving some mineral at the source of the drip at the roof of the cave and some where it falls.
Carbonate chemistry — Science Learning Hub
Calcium carbonate is unusual in that its solubility increases as the temperature of the water decreases. The increased solubility of calcium carbonate in rainwater saturated with carbon dioxide is the driving force behind the erosion of limestone rocks, leading to the formation over long periods of time of caverns, caves, stalagmites and stalactites.
