please answer me ​

Answer 1

Answer:

Less amount of useful or drinkable water.

Explanation:

70% of earth surface is coverd with water, inspite of that, there is scarcity of water because approximately 99% of water is very salty i.e. sea or ocean water so there is very less amount of useful or drinkable water.

Answer 2

Though 3/4th of the Earth's surface is covered with water, only 0.8 of fresh water is available to us in the form of ground water and surface water. This water gets contaminated by various ways. Also, due to reduced rainfall the water table also decreases. This has resulted in the scarcity of water.
