Coal is extracted from the ground using one of two different methods:

  • Surface mining - the coal is found near the surface and large holes are dug to extract the coal.
  • Underground mining - the coal is found deep under the surface and tunnels are dug to extract the coal.

Suggest and explain which method is cheaper.
