Question

71% of the earth's surface is covered with water, but we still face water shortage. What can be the possible reason for this?

• A.
  Ocean water vaporises quickly.
• B.
  Most of the available water is salty and unfit for consumption.
• C.
  Ocean water is full of disease-causing microbes.
• D.
  Most of the water is present in the form of vapours in the atmosphere

Answer 1

The correct option is B

Most of the available water is salty and unfit for consumption.

• Though, about 71% of the Earth’s surface is covered with water, we still face water shortages.
• It is because only 3% of water is freshwater and 97% of the water is available in oceans as salty water which is unfit for consumption.
