Which gas is dominant among permanent gases of the atmosphere?
Answer and explanation
Correct answer: Nitrogen
Nitrogen is the dominant permanent gas in the atmosphere, forming about 78% of dry air. Permanent gases remain relatively stable in proportion over short periods, unlike water vapour, which changes greatly with humidity, temperature and weather. Therefore option D is correct. Ozone is present only in trace amounts, while dust is a solid aerosol rather than a dominant permanent gas.
