Why does local air quality keep changing despite the near stability of permanent gases in the atmosphere?
Answer and explanation
Correct answer: Because pollutant gases, particles and water vapour change locally
The governing concept is the distinction between relatively stable major gases and variable atmospheric components. Emissions from traffic, industry, fires and other sources can change pollutant concentrations locally, while wind, mixing, humidity and rainfall redistribute or remove them. Thus A explains changing air quality. B and C exaggerate changes in permanent gases, and D wrongly assigns pollution to inert argon.
