Question

Although coal and petroleum are produced by degradatioin of biomass, yet we need to conserve them. Why?

• A. Both are the energy sources.
• B. Coal and petroleum take millions of years for their formation.
• C. If the resources are being utilised at a much faster rate than their formation, they will be exhausted in the near future.
• D. Both B and C.

Answer 1

The correct option is D Both B and C.

Coal and petroleum have to be conserved because:

• Coal and petroleum take millions of years for their formation.
  
• If the resources are being utilised at a much faster rate than their formation, they will be exhausted in the near future.
  

It is correct that both these natural resources, coal and petroleum are produced by biodegradation of plants and animal wastes, but it takes of thousands of years for their formation. This is the reason we need to conserve them for our future generations, as we are using them on much faster rate compared to the rate at which these are formed. These natural resources are called as non-renewable resources.
