What is one simple importance of nitrogen in the atmosphere?
Answer and explanation
Correct answer: It helps keep the oxygen concentration balanced
Nitrogen is a relatively unreactive gas and forms the largest part of air, while oxygen forms about one-fifth. Its large presence dilutes oxygen and helps prevent combustion from becoming excessively rapid. It does not remove all water vapour, destroy the ozone layer, or create oceans. Thus option D expresses the intended basic importance.
