What is the most scientific difference between permanent gases and variable components in the atmosphere?
Answer and explanation
Correct answer: Permanent gases have relatively stable proportions
The governing concept is atmospheric composition and its degree of spatial and temporal variation. Permanent gases, such as nitrogen and oxygen, generally maintain nearly stable proportions in the lower atmosphere, although their absolute density changes with altitude. Variable components, including water vapour, dust, and carbon dioxide, change with place, season, weather, and human activity. Thus B is correct; A, C, and D make absolute claims that are false.
