Which of the following is not a greenhouse gas?

Explanation:

Greenhouse Effect: The solar energy trapped by the earth atmosphere and radiate it slowly so to cover our earth with a warm blanket. This is the natural process of the greenhouse effect on earth to maintain its temperature and makes the earth perfect for life.

Greenhouse gases are carbon dioxide, other greenhouse gases are methane, water vapour, nitrous oxide, CFCs and ozone. 

Values of radiation absorbed by the greenhouse gases are as follow:

From the above table it is clear that carbon dioxide absorbs the maximum radiation in the earth’s atmosphere

Hence the correct option is sulphur dioxide (SO2) which is not a greenhouse gas.

The major greenhouse gases are

• Water vapour - causes about 36% - 70% of the greenhouse effect
• Carbon dioxide (CO2) which causes 9 - 26%
• Methane (CH4) causes 4 - 9%
• Ozone (O3)
• Nitrous Oxide
• Chlorofluorocarbons (CFCs)

Important Points

Global warming: If the amount of greenhouse gases crosses by delicate proportion, the natural greenhouse balance may get disturbed and there is a continuous rise in temperature of the earth by trapping the solar heat continuously. This creates the overall effect of Global warming.
