Question 2

Seas and oceans are full of water on earth. However, a very small percentage of water present on earth is available for us. This percentage is roughly
(a) .006%
(b) 0.006%
(c) 0.6%
(d) 6%

Answer 1

Most of the water present on earth is not fit for consumption by us. Sea and oceans contain salty water which cannot be drunk. Even most of the fresh water is frozen as ice in glaciers and polar regions. Hence, we are left with limited amount of water from river, lake and from under the ground. Thus the percentage of water for consumption is roughly is 0.006%
