What is the importance of dust particles for cloud formation in the troposphere?
Answer and explanation
Correct answer: They can act as condensation nuclei
The governing concept is condensation. Air may contain water vapour, but cloud droplets form more readily when vapour condenses on tiny solid or liquid particles. Dust, salt and smoke particles can provide surfaces called condensation nuclei. Therefore option A is correct. Dust does not destroy the stratosphere, alter the Sun’s distance, or create rainfall in the exosphere; those alternatives confuse local cloud physics with unrelated atmospheric ideas.
