classify the resources on the basis of exhautibility in two groups mention three characters of each
Answers
Explanation:
(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.
Answer:
On the basis of exhaustibility, resources can be classified into two groups: Renewable and non-renewable resources. Their chief characteristics are
Renewable resources
1. These resources are found abundantly in nature (e.g. sunlight and wind).
2. These resources can be renewed and replenished with the help physical, chemical or mechanical processes (e.g. wildlife and water).
3. Although these resources are found abundantly in nature, some of them may take longer time in getting replenished. For example, water and forests take a longer time in getting replenished.
Non-renewable resources
1. These resources occur over long geological time. For example, coal and petroleum take millions of years for their formation.
2. Some of these resources (e.g. metals) can be recycled, while some of the resources (e.g. coal and other fossil fuels) cannot be recycled.
3. At present, the main energy sources used by humans are generally non-renewable resources such as coal and petroleum.
