Limestone - Wikipedia

Limestone is a common type of carbonate sedimentary rock.It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes have likely been more ...

How Does Weathering Affect Limestone?

Apr 14, 2020 · Limestone is a sedimentary rock created from the remains of dead sea creatures and is predominately made up of calcium carbonate. Many horizontal and vertical cracks run through limestone. These cracks allow water to pass easily through the rock. Water acts as an acid when it contacts calcium carbonate, dissolving the limestone.

How does weathering affect limestone? - Internet Geography

Weathering is the breakdown of rock by physical, chemical or biological processes. Limestone areas are predominantly affected by chemical weathering when rainwater, which contains a weak carbonic acid, reacts with limestone. This causes the limestone to dissolve. Carbon dioxide from the respiration of animals (and ourselves) is one cause of increased carbon dioxide in the atmosphere.
