Sources Of Water

Do you know that on an average an individual consumes about 2.9 litres of water everyday?

Recall a picture of the globe. The area covered by the land is very small as compared to the area covered by water. Water covers two-third (2/3) of the total surface area of the world.

Interestingly, did you know that some of the water from the oceans and seas evaporates and is the primary source of rain? Rainwater feeds into the ponds, lakes, rivers, and wells etc, which in turn are the main sources of water for us.
