A sand quarry is a sand depression that results from digging or mining the ground. Quarries generally are created when hard mineral deposits such as rock, marble, clay, gravel, and sandstones are mined.
A quarry is a type of open-pit mine, because it is open to the Earth’s surface. They can often be several miles deep.
Aggregate is what is extracted from a quarry in terms of sand, gravel, or crushed rock. Concrete and asphalt are made from aggregate, which is also used in construction to build sturdy foundations for things like highways and train tracks.
