What is the most correct practical importance of abundant nitrogen in the atmosphere?
Answer and explanation
Correct answer: It balances oxygen and keeps combustion controlled
Option B is the best answer. Nitrogen forms about 78% of air and is comparatively unreactive under ordinary conditions. Its large proportion dilutes oxygen, so burning is not as rapid or aggressive as it would be in pure oxygen. Nitrogen does not form all clouds; water vapour is essential for clouds. The ozone layer mainly absorbs ultraviolet radiation, and plants use carbon dioxide—not nitrogen—as the carbon source in photosynthesis. Nitrogen is important to plants after fixation into usable compounds, but that is different from being the main photosynthetic gas.
