Question

What do you know about limestone?

Answer 1

Limestone is a common, chemical sedimentary rock formed primarily from calcium carbonate. It is generally light-colored and can also include fossils of calcium carbonate-containing organisms, like corals. Limestone can be found all over the world and is the major type of rock found in karst features (crystal cave systems found in bedrock).

Of all the sedimentary rocks found on Earth, almost ten percent of them are some form of limestone. Because it is widely available, it has been used throughout the centuries for many uses, from building materials to chemical additives. Two of the most famous limestone deposits are the islands of the Florida Keys and Niagara Falls.
