Mining is defined as

Mining is defined as

• A. A dangerous practice that involves extracting resources from the Earth.
• B. The renewable harvesting of energy from ocean tides.
• C. The process of refining metals to improve purity.
• D. A legal framework for managing natural resources.

Answer: (A)

Mining is the process of extracting valuable resources from the Earth's crust. The essential idea is the act of pulling minerals or other geological materials out of the ground to obtain them. While mining can involve hazardous conditions in practice, the defining concept is the extraction of resources from the Earth, not the danger itself. The other options describe different ideas: tidal energy harvesting is about capturing energy from tides, refining metals is a processing step after ore is mined, and a legal framework deals with rules for managing resources rather than the act of obtaining them.
