quarry National Geographic Society

A quarry is a place where rocks, sand, or minerals are extracted from the surface of the Earth. A quarry is a type of mine called an open-pit mine, because it is open to the Earth's surface.Another type of mine, a sub-surface mine, consists of underground tunnels or shafts.. The most common purpose of quarries is to extract stone for building materials.
