Natural Resources

The resources available on the Earth and the Energy from the Sun are the necessary elements to meet the basic requirements of all the life forms on the Earth. These stocks of nature which are useful and necessary for mankind are known as Natural Resources.


The blanket of air which surrounds the Earth is known as the Atmosphere.

It is very important to our environment because it carries out all the agricultural processes in the plants. Therefore, conserving rain is very important and we can conserve it by constructing dams, pools etc.

Acid Rain
