The Green House Effect

The greenhouse effect is the increase in temperatures attributed to gases in the Earth's atmosphere that capture the Sun's energy.

1. The Sunlight passes through the atmosphere.
2. About a third of the energy is immediately reflected back to space by earth's atmosphere.
3. Rest of the energy is absorbed by earth and warms the planet.
4. This heat becomes infra-red radiation and is reflected back to space.
5. The shield of green house gases trap this heat, making the planet even warmer.
