Which of the following resources is renewable ?

  • A.Coal
  • B.Petroleum
  • C.Natural gas
  • D.Forest

Answer: D

The renewable resource is the forest.

A renewable resource is one that is replenished by natural processes within a human time scale. Forests regrow through natural regeneration and planting, so they can be used sustainably if cutting does not exceed regrowth.

Coal, petroleum and natural gas are fossil fuels. They formed from buried organic matter over millions of years, and the stocks used today cannot be replaced on any useful time scale, so they are non-renewable.
