How can the presence of dust particles help initiate rainfall?
Answer and explanation
Correct answer: They provide centers for water vapour condensation
Dust particles can act as condensation nuclei, providing surfaces on which water vapour begins to condense when moist air cools. Many tiny droplets may then grow through collision, coalescence, or ice-related processes until they become heavy enough to fall as precipitation. Dust does not chemically transform oxygen, nitrogen, or argon into water; its role is mainly physical and indirect.
