A greenhouse effect is the process that raises the temperature of air in the lower atmosphere due to Heat trapped by greenhouse gases, such as carbon dioxide, methane, nitrous oxide,
chlorofluorocarbons, and ozone.
Other /More definition:
A Greenhouse effect is the effect produced as greenhouse gases allow incoming solar radiation to pass through the Earth's atmosphere, but prevent part of the outgoing infrared radiation from the Earth's surface and lower atmosphere from escaping into outer space. This process occurs naturally and has kept the Earth's temperature about 59 degrees F warmer than it would otherwise be. Current life on Earth could not be sustained without the natural Greenhouse effect.
Other /More definition:
Greenhouse effect is a natural effect that releases heat in the atmosphere (troposphere) near the earth's surface. Water vapor, carbon dioxide, ozone, and other gases in the lower atmosphere (troposphere) absorb some of the infrared radiation (heat) radiated by the earth's surface. Their molecules vibrate and transform the absorbed energy into longer-wavelength infrared radiation (heat) in the troposphere. If the atmospheric concentrations of these greenhouse gases increase and other natural processes do not remove them, the average temperature of the lower atmosphere will increase gradually. Compare
global warming. See also natural greenhouse effect.
Other /More definition:
The Greenhouse Effect is a natural phenomenon that maintains an average temperature of 15°C on the planet. Emissions caused by human activities, which contribute greenhouse gases, such as carbon dioxide (CO2) and methane (CH4), disrupt the thermal balance between energy radiated from the sun and the longwave radiation being radiated to space. This disruption is believed to be the cause of climate change.
