greenhouse effect

Greenhouse Effect This effect is the result of certain atmospheric gases letting sunlight through to the earth's surface, while not letting energy radiated outward from the earth's surface. This results in a net buildup of solar energy in the Earth's atmosphere, because the flow in is greater than the flow outwards. The chemicals that are most significantly involved in this effect are chloroflurocarbons (CFCs), hydrogenated chloroflurocarbons (HCFCs), nitrous oxide (N2O), and tropospheric ozone (O3). …
