process of formation of limestone rocks

Sinkholes USGS

Oct 16, · In these areas the formation of underground cavities can form, and catastrophic sinkholes can happen. These rock types are evaporites (salt, gypsum, and anhydrite) and carbonates (limestone and dolomite). Evaporite rocks underlie about 35 to 40 percent of the United States, though in many areas they are buried at great depths.

Formation of igneous rocks. Igneous rock forms when hot liquid rock called magma cools. When the magma cools below the Earth's surface it cools slowly forming large crystals and is known as an intrusive igneous rock e.g. granite (pictured to the right). When magma reaches the Earth's surface, usually through a volcano, it is called lava and it cools quickly, rocks formed by this process are
