Water covers about 70% of Earth's surface.The presence of water makes the Earth look blue from space.This is why we call the Earth the 'BLUE Planet'. With so much water present on the Earth, why do we talk about water shortage? The oceans and seas contain about 97.5% of all the water present on the Earth. This water is salty and cannot be used. Only 2.5%of all the water present on the Earth is fresh water.

The icecaps and glaciers contain around 69% of the fresh water .The water present under the ground as groundwater makes up around 30% of the fresh water.So, only 1% of fresh water (that is, 0.025% of all the water on the Earth) is found on the surface.A part of this water is available for use in lakes and rivers.
