WATER RESOURCES ON EARTH

Freshwater is a precious and scarce natural

resource.
Why? Because freshwater accounts for only

2.5% of the Earth's water, 70% of which is in
the form of glaciers and snow caps in the

poles and mountainous regions.
The rest is salt water which is not potable.

In a nutshell, suppose Earth's water is

represented by 100 cups, only 2.5 cups are
freshwater.
