Answer :

Final answer:

Removing dirt and rock to access a near-surface mineral deposit is known as surface mining. This method includes techniques like open-pit mining and strip mining. It is particularly useful for extracting minerals like bauxite that are found close to the Earth's surface.


Explanation:

Understanding Surface Mining

Removing dirt and rock that overlies a mineral deposit close to the surface to access the deposit is referred to as surface mining. This method is characterized by the extraction of resources such as minerals and ores that are located near the Earth's surface.

Surface mining involves various techniques, including:

  • Open-pit mining: A widespread method where a large pit is dug to access minerals.
  • Strip mining: This involves removing overburden in long strips to expose the mineral beneath.
  • Mountaintop removal: This destructive method blasts away overburden to reach coal seams.

All these methods remove the top layers of earth to reach valuable mineral resources below. For example, bauxite, which is often found near the surface, is typically extracted using surface mining techniques, illustrating the suitability of this method for accessible deposits.
