Greenhouse effect:-

1. The greenhouse effect is defined as when the Earth's atmosphere becomes thick with gases and substances which trap the sun's radiation, making the Earth warmer.
2. An example of the greenhouse effect is global warming.
3. The greenhouse effect is a warming of Earth's surface and the air above it.
4. It is caused by gases in the air that trap energy from the Sun.
5. These heat-trapping gasesare called greenhouse gases. ... Without the greenhouse effect, Earth would be too cold for life to exist.
