Which of the following statements about large scale mineral extraction is true? a. the economic benefits of large scale mineral extraction outweigh the environmental costs. b. large scale mineral extraction is more destructive than in the past. c. large scale extraction is vital to the economy of mining towns. d. mineral extraction cannot be done in ways that do not completely destroy the environment.

Answer;

C. Large scale extraction is vital to the economy of mining towns.

Explanation;

-Extraction of Mineral Resources involves extraction of solid, liquid, and gaseous mineral products from the earth’s interior.

-The process of extracting mineral resources involves digging them out and transporting them from the faces to the surface outside the mining excavation. Solid mineral products are extracted by the open-pit and underground methods.

-Peat is extracted from the surface with full mechanization of the basic production processes. The extraction of liquid mineral products and natural gas by wells drilled from the surface is being done on an ever-increasing scale.

-In states and regions where mining is concentrated the industry plays a much more important role in the local economy. Overall, the economy cannot function without minerals and the products made from them.
