Important Points
-
The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without this atmosphere.
-
Radiatively active gases (i.e. greenhouse gases) in a planet's atmosphere radiate energy in all directions. Part of this radiation is directed towards the surface, thus warming it.
-
The intensity of downward radiation – that is, the strength of the greenhouse effect – depends on the number of greenhouse gases that the atmosphere contains. The temperature rises until the intensity of upward radiation from the surface, thus cooling it, balances the downward flow of energy.
The Greenhouse Gases are
-
Carbon Dioxide
-
Water Vapour,
-
Nitrogen Oxide (N2O),
-
Methane
-
Nitrogen oxide
-
Ozone
-
Fluorinated Gases
-
Black Carbon
- Carbon Tetrachloride
