A part of the sun's rays is absorbed by the earth.

A part of the sun's rays is reflected back in space.

A part of reflected rays is trapped by greenhouse gases.

The trapped radiations of the sun warm the earth.

Have you ever seen a greenhouse in a nursery?

In a greenhouse, the sun's heat can come in.

This trapped heat helps in controlled growth of plants.

In a greenhouse, the sun's heat can come in but cannot go out.

Similarly, as these gases trap the sun's heat, they are called greenhouses gases.

If there were no greenhouse gases to trap the sun's radiation the earth would be a very cold place where we would not survive.

This trapping of heat to keep the earth warm is called greenhouse effect.
