what is the limestone reaction cycle

Limestone reactions, gcse chemistry, calcium carbonate

Limestone is mainly composed of the compound calcium carbonate (CaCO 3). Limestone is a sedimentary rock which was formed from the shells of sea creatures that lived millions of years ago. Limestone is quarried and can be used to produce cement, glass and concrete. Cement. Limestone is heated with clay to make cement in a rotary kiln.

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.

what is the limestone cycle ? | S-cool, the revision website

Limestone is mainly calcium carbonate, CaCO3, which when heated breaks down to form calcium oxide and carbon dioxide. Calcium oxide reacts with water to produce calcium hydroxide. Limestone and its products have many uses, including being used to make cement, mortar and concrete. Thermal decomposition Calcium carbonate breaks down when heated strongly.

Limestone Facts

Limestone is a sedimentary rock that contains at least 50% calcium carbonate (CaCO3). Because sedimentary rocks are made of various types of sediments, the other 50% of a limestone rock could be virtually any other mineral. Limestone originates in wet areas which mean it could also be composed of shells and waste matter from organisms.
