Question

Explain why fossil fuels are exhaustible natural resources. [2 marks]

Answer 1

The process of the formation of fossil fuels requires millions of years. [1 mark]
Dead vegetation and animals that get buried deep inside the earth require high temperature and pressure for the formation of fossil fuels, which cannot be done in the laboratory. Thus, fossils are limited. Therefore, the use of fossil fuels at a rapid rate will lead to their exhaustion. [1 mark]
