Why is N₂O linked with both climate and atmospheric chemistry?
Answer and explanation
Correct answer: Because it is a trace greenhouse gas and can participate in atmospheric chemical processes
The governing concept is that trace gases can still be chemically and climatically active. Nitrous oxide is present in a small concentration, but it absorbs outgoing infrared radiation and therefore contributes to the greenhouse effect. It can also undergo reactions in the atmosphere, especially in the stratosphere, where it influences nitrogen-oxide chemistry. Thus B is correct; A, C and D incorrectly describe its colour, abundance or chemical effect.
