Which is an example of a permanent gas in the atmosphere?
Answer and explanation
Correct answer: Nitrogen
Nitrogen is a permanent gas and forms about 78% of dry air, so option B is correct. Permanent gases have relatively stable proportions throughout the lower atmosphere. Water vapour changes greatly with location, temperature, and season. Carbon dioxide and ozone are present in small amounts and can vary because of natural processes and pollution. Thus, nitrogen is the clearest example among the choices.
