Answer Details
Limestone is an example of an organically formed sedimentary rock. It is primarily composed of calcium carbonate, which is the skeletal remains of marine organisms such as coral and shells. Over millions of years, the accumulation of these organisms on the ocean floor is compacted and cemented together to form limestone.
Limestone can also be formed through chemical precipitation, where minerals in water are deposited in caves and underground formations. It is a versatile rock and can be used for a variety of purposes, including construction, as a source of lime for agriculture, and in the production of cement. Due to its porous nature, limestone can also be a source of groundwater and is often used as a natural filter for drinking water.
