Answer 2

Three fourths

Three fourths of the Earth is covered by water. In that 75%, majority is salty water and fresh water is found in very less proportion. It is surprising that we are surviving due to that small amount of fresh water.

Similarly, the atmosphere of Earth, which is held by the Gravitational force, is divided into several parts due to the concentration of several gases. Nitrogen gas (N2) is present about 78.9% and Oxygen Gas (O3), 20.1%. Argon, CO2, H2O vapour is present in very small quantities.
