Question

Classify resources, on the basis of exhaustibility in two groups. Mention three characteristics of each.

Answer 1

(i) Renewable resources: Resources that can be renewed or reproduced by mechanical, physical or chemical processes are known as renewable or replenishable resources, e.g., solar and wind energy, water, forests, and wildlife, etc.

(ii) Non- renewable resources: These occur over very long geological times. Minerals and fossil fuels are examples of such resources. These resources take millions of years in their formation. Some of the resources like metals are recyclable and some of them such as fossil fuels cannot be recycled and get exhausted with their use.
