The Carbon Cycle
The acid dissolves rocks—a process called chemical weathering—and releases calcium, magnesium, potassium, or sodium ions. Rivers carry the ions to the ocean. Rivers carry calcium ions—the result of chemical weathering of rocks—into the ocean, where they react with carbonate dissolved in the water.

Calcium Carbonate
Calcium Carbonate is a chemical compound having the chemical formula CaCO3. It is a white and insoluble powder-like substance that occurs naturally in minerals, marble, chalk, limestone, shells, calcite, pearl, and other related compounds. Medicinally, we use it as an antacid or a calcium supplement. It can also be used as cosmetics fillers.
