Here's why:

* Surface Mines: Extract minerals from the earth's surface, typically by digging an open pit.

* Underground Mines: Access minerals through tunnels and shafts that go deep into the earth.

Quarries specifically focus on extracting dimension stone, which means large blocks of rock like granite, marble, limestone, or sandstone. These blocks are then used for building materials, landscaping, and other purposes.

So, while a quarry is a type of mine, it's specifically a surface mine that focuses on extracting dimension stone.
