What is Greenhouse Gases??

Greenhouse Gases are gases in the atmosphere that emit and absorb radiation with thermal infrared range.

They are almost transparent to solar radiation, but emits and absorbs infrared radiation absolute strongly.
These gases include: water vapour, carbon dioxide, methane, ozone, chlorofluorocarbons and nitrus oxide.

Greenhouse Gases, especially water vapour, are important to Earth as they help to really determine the temperature.
WIthout the existence of Greenhouse Gases, Earth will be so cold that it will be totally impossible for human survival.




The distribution of Greenhouse Gases:





























The Greenhouse Effect is the heating up of Earth's surface due to the presence of the Greenhouse Gases which absorb and emit infrared radiation.

The Greenhouse Effect is already getting a little stronger. Just some more heat may cause some serious problems for all living organisms- Humans, Plants and Animals.
