Why is carbon dioxide considered variable compared with permanent gases?
Answer and explanation
Correct answer: Because its amount changes through natural and human processes
Permanent gases such as nitrogen and oxygen have relatively stable proportions in the well-mixed atmosphere, whereas carbon dioxide changes with location, season and human activity. Respiration, decomposition, oceans and photosynthesis exchange carbon dioxide, while combustion and land-use change can add more. Hence option B is correct; A, C and D contradict these facts.
