Quarries are made when big deposits of commercially helpful minerals or rock are found close to the Earth's surface. Quarrying is a type of mining and is also called as open pit mining or strip mining. When minerals are found profound beneath the surface, a deep mine has to be dug to dig out them. Quarries are normally dug deeper and bigger
