GEOLOGY

Detailed explanation-1: -Common sedimentary rocks include sandstone, limestone, and shale.

Detailed explanation-2: -Limestone is a sedimentary rock made of calcium carbonate (CaCO3), usually in the form of calcite or aragonite.

Detailed explanation-3: -Limestone is a sedimentary rock that is dominantly composed of the calcium-bearing carbonate minerals calcite and dolomite. Calcite is chemically calcium carbonate (formula CaCO3).

Detailed explanation-4: -Sedimentary rocks are formed on or near the Earth’s surface, in contrast to metamorphic and igneous rocks, which are formed deep within the Earth. The most important geological processes that lead to the creation of sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification.

Detailed explanation-5: -Because limestone contains the remains of dead organisms, it is considered an organic sedimentary rock. There are rare chemical sedimentary rocks that form from the precipitation of calcium carbonate from ocean water.
