Question

Which one of the following is NOT a green house gas found naturally in the atmosphere ?

Answer & Solution

Answer: (Detailed Solution Below)

Option A: Nitrogen oxide

Detailed Solution:

The correct answer is “Nitrogen oxide”.
Nitrogen oxide is not a greenhouse gas found naturally in the atmosphere.

Nitrogen oxides (NOₓ) are primarily produced from human activities, such as combustion processes, and are not considered a significant naturally occurring greenhouse gas.

Nitrous oxide (N2O) is a greenhouse gas. Nitrous oxide gas should not be confused with nitric oxide (NO) or nitrogen dioxide (NO2). Neither nitric oxide nor nitrogen dioxide are greenhouse gases, although they are important in the process of creation of tropospheric ozone which is a greenhouse gas.
