Dust particles are important in cloud formation because of which role?
Answer and explanation
Correct answer: They provide condensation nuclei
Dust particles act as condensation nuclei, which are tiny surfaces on which water vapour can condense. When moist air cools to saturation, water collects around these particles and forms small droplets; many droplets together can develop into clouds. Dust does not produce oxygen, remove atmospheric nitrogen, or liquefy ozone. Therefore option A correctly explains its role in cloud formation.
