Which of the following correctly represents the relative amount of saline water, frozen water and usable surface water on the Earth?
Freshwater is naturally available water with very little salt in it. Out of all the water present on the Earth, 97% of it is saline and it is unfit for drinking and domestic use. Only 3% of the Earth’s water is freshwater. Out of 3% of freshwater, 68.7% is frozen, which is found in glaciers and icecaps. 30% of the freshwater is found under the ground and 0.3% is usable surface water which is found on the Earth's surface.
Hence option b represents the correct order of the relative amount of saline water, frozen water and usable surface water on the Earth.
