Write short note on Greenhouse effect.

Explanation

Greenhouse effect is the trapping of the sun.s radiation in a glass house, the glass does not allow this heat energy to escape. The same situation is observed in a car parked in the sun, the inside of the car becomes hot. There are some gases, called the greenhouse gases (such as `CO_2, CH_4`, ozone etc.) present in the atmosphere which absorb the IR radiations coming from the sun and cause global warming.
