Nitrogen gas is so cold that moisture in the air condenses on it, creating a dense fog.

The increase in the levels of greenhouse gases results in the gradual increase of temperature of the earth’s surface.

Rain water is actually the purest form of water.

An average increase in the temperature of the atmosphere is called as acid rain.

Acid rain inhibits germination and growth of seedlings.

Nitrogen is an essential element present in proteins and nucleic acids which are the building blocks of living things.
