If smoke and fine particles increase in a city, which atmospheric component is considered increased?
Answer and explanation
Correct answer: Aerosols
The governing concept is the classification of suspended atmospheric particles. Smoke contains very small solid or liquid particles dispersed through air; such suspended particles are classified as aerosols. A rise in aerosol concentration can reduce visibility, worsen air quality and affect radiation. Therefore B is correct. Smoke does not automatically mean more water vapour or argon, and it does not represent an increase in pure oxygen, so A, C and D are unsuitable.
