Explanation:
<em>The greenhouse effect is a process that occurs when gases in Earth's atmosphere trap the Sun's heat.</em> Gases in the atmosphere such as CO2, water vapor, methane, nitrous oxide, ozone and some artificial chemicals such as chlorofluorocarbons absorb and re-radiate the sun's energy maintaining the Earth's temperature at around 33 degrees Celcius, this happens especially with infrared light that wants to go back to space. This infrared heat spreads back to the land and oceans. This absorption does not happen with visible light, the radiation at 400-800nm easily passes through the atmosphere.
