Which of the following is not a greenhouse effect gas?

Correct option is D

The Correct Answer is Nitrogen
The greenhouse effect is the process by which solar energy is trapped by the Earth's atmosphere and radiates slowly, essentially creating a natural warm blanket around Earth. This process is vital for maintaining the Earth's temperature and ensuring it remains suitable for life.
The main greenhouse gases include:
· Carbon dioxide (CO₂)
· Methane (CH₄)
· Water vapor (H₂O)
· Nitrous oxide (N₂O)
· Ozone (O₃)
· Chlorofluorocarbons (CFCs)
These gases absorb infrared radiation emitted by the Earth's surface, thereby trapping heat. From the list above:
· Nitrogen (N₂), however, is not a greenhouse gas. Nitrogen makes up approximately 78% of Earth's atmosphere, but it does not trap heat in the same way other gases like CO₂ or CH₄ do. Nitrogen is an inert gas and does not contribute to the greenhouse effect.
Information Booster:
· Greenhouse gases' role:
· Water vapour: Contributes 36% - 70% to the greenhouse effect.
· Carbon dioxide (CO₂): Contributes 9% - 26%.
· Methane (CH₄): Contributes 4% - 9%.
· Ozone (O₃): Also plays a role in absorbing radiation.
· Nitrous oxide (N₂O) and CFCs contribute in smaller amounts.
· Absorption values of greenhouse gases (percentage of radiation absorbed):
· Ozone (O₃): 10.2%
· Methane (CH₄): 16.3%
· Carbon Dioxide (CO₂): 56.4%
· Nitrous Oxide (N₂O): 5.4%
