Which effect of dust particles in the atmosphere can be considered positive?
Answer and explanation
Correct answer: They help form cloud droplets by providing condensation nuclei
The governing concept is condensation in the atmosphere. Water vapour needs suitable surfaces on which it can begin changing into liquid droplets, and tiny dust particles can provide those condensation nuclei. This supports cloud formation and may contribute to rainfall. Option A is therefore correct. Dust does not increase visibility, produce oxygen, or serve as the main gas supporting combustion.
