Question 3.
(a) Mining refers to all attempts to attract valuable minerals either solid, liquid or gas from the earth’s crust.
(b) Two factors that have influenced exploitation of minerals.
- Minerals that are of high demand and economic value may be mined at a very high cost because they can be sold at high prices e.g. gold, petroleum e.t.c.
