Answer: False. Explanation: Surface mining disturbs more land compared to subsurface mines. During surface mining, huge mounds of earth is removed inorder to access mineral deposits. The deeper lying the deposit, the more the earth is removed and disturbed. In subsurface mines, tunnels and a system of shaft are used to access the ore body.
