William Beyer (pers.A sedimentary rock, limestone is composed from calcium carbonate, forming when other types of rock are subject to a sequence of weathering and erosion known as denudation: Mechanical weathering from ice, water flow, waves, rain, wind or thermal activity strips or grinds down parts of the origin rock, with particles being eroded, or transported ... Limestone is a sedimentary rock, although it has a hardness of 3-4 Mohs and a density of 2.5 to 2.7 grams per cubic centimeter. The rock is primarily composed of calcite or calcium carbonate, with most of these rocks being around 95% calcium carbonate.
