What is the difference between an open pit mine, a quarry and an underground mine with shafts?

Model Answer & Options

Source: Textbook

An open-pit mine is used for extracting minerals that are found close to the surface, creating a large conical pit. A quarry is very similar but is used specifically for extracting building materials like stone and gravel. In contrast, an underground mine is for deep-seated mineral deposits. It uses vertical shafts to access the deposits and horizontal tunnels to extract the ore, without removing the surface rock.
