=__**Greenhouse effect**__=

The "greenhouse effect" is when certain gases are in the Earth's atmosphere, trapping the heat from escaping, the atmosphere is like the glass walls of a greenhouse. About 31% of the sun is reflected of the incoming radiation, another 20% of the atmosphere is absorbed. The rest of the incoming radiation is absorbed by the earth's oceans and land, where it is converted into heat, warming the surface of the earth and the air above it.
