In which process is the combined role of water vapour and dust particles most evident?
Answer and explanation
Correct answer: Condensation of cloud droplets and initiation of rainfall
Water vapour changes into liquid droplets when air cools to saturation. Dust and other tiny particles act as condensation nuclei, providing surfaces on which water vapour can collect. The droplets may grow, combine and eventually contribute to precipitation. Therefore option B correctly connects both atmospheric components with cloud formation and the beginning of rainfall. Earthquakes, rock metamorphism and ocean salinity are unrelated to this combined process.
