Question

Arrange the following in increasing order of percentage of availability.
1. Seawater
2. Surface water
3. Water in glaciers

• A. 3 < 2 < 1
• B. 1 < 2 < 3
• C. 2 < 3 < 1
• D. 3 < 1 < 2

Answer 1

The correct option is C 2 < 3 < 1

Seas and oceans comprise 97% of the water on the Earth.
The percentage of fresh water on the Earth that can be used for drinking is 3%.
If we take this 3% freshwater as 100 % freshwater on Earth, then 68.7% of it is occupied by glaciers and icecaps, 30% is groundwater and only 0.3 % is surface water.
So, option D is correct answer.
