What is surface and subsurface mining, and examples, in simple words?
Understand the Problem
The question is asking for a simple explanation of surface and subsurface mining, along with examples of each. This will involve describing the two types of mining, how they differ, and providing instances where each type is used.
Answer
Surface mining removes overburden to access minerals; subsurface mining involves tunneling underground.
Surface mining involves removing soil, rocks, and vegetation to access minerals near the Earth's surface. Examples include open-pit and strip mining. Subsurface mining involves tunneling underground to reach minerals beneath the Earth's surface, like in shaft and drift mining.
Answer for screen readers
Surface mining involves removing soil, rocks, and vegetation to access minerals near the Earth's surface. Examples include open-pit and strip mining. Subsurface mining involves tunneling underground to reach minerals beneath the Earth's surface, like in shaft and drift mining.
More Information
Surface mining is generally used for minerals that are close to the surface, while subsurface mining is used for minerals located deeper underground. Surface mining is typically less expensive but more environmentally disruptive than subsurface mining.
Tips
A common mistake is confusing the methods for their environmental impacts. Surface mining disrupts the landscape more, while subsurface mining can affect underground water flow.
