What is the calcium carbonate cycle?

Answer 1

Plants and animals that secret lime (CaCO3) flourish in tropical seas. Shells Of CaCO3 in many pile up in shallow off shore waters where they cemented themselves into limestone.

Slightly acid grown water is a solvent of limestone, and creates tunnels, caves, and even caverns along cracks or joints in the rock.

Some of the dissolved calcium carbonate is redeposit in caves and caverns stalactites and stalagmites.

Answer 2

The calcium carbonate cycle is a natural process that involves the formation, distribution, and dissolution of calcium carbonate in various forms. It plays a critical role in regulating the pH levels of the ocean and in carbon sequestration. In this cycle, calcium carbonate is used by marine organisms like corals and shellfish to build their shells, which eventually accumulate and form sediments on the ocean floor.
