Greenhouse Effect:

The greenhouse effect is a naturally occurring phenomenon that is responsible for heating of Earth’s surface and atmosphere.

Solar energy is trapped by the earth’s atmosphere and radiates slowly so as to cover our earth with a warm blanket.

This is the natural process of the greenhouse effect on earth to maintain its temperature and makes the earth perfect for life.

Without the greenhouse effect, the average temperature at the surface of Earth would have been chilly –18oC rather than the present average of 15oC.

Carbon dioxide, methane and water vapour are the major greenhouse gases that absorb the infrared radiation from the Earth and re-emit it.
