Question

Which of the following is NOT a green house gas?

Answer & Solution

Answer: (Detailed Solution Below)

Option A: Argon

Detailed Solution:

The correct answer is “Argon”.
Argon is a noble gas that does not contribute to the greenhouse effect. It is chemically inert and does not absorb or emit infrared radiation, which is the characteristic of greenhouse gases.

The primary greenhouse gases in Earth's atmosphere are water vapor (H 2O), carbon dioxide (CO 2), methane ( CH 4), nitrous oxide ( N 2O), and ozone (O3).
1) CFCs contribute to ozone depletion and have a significant greenhouse effect.

2) Methane is a potent greenhouse gas, much more effective at trapping heat than carbon dioxide.

3) Carbon dioxide is the most significant greenhouse gas emitted by human activities, primarily through the burning of fossil fuels.
