Why can cloud-droplet formation be difficult without condensation nuclei?

Answer and explanation

Correct answer: Because droplets need tiny surfaces or bases on which to form

Correct answer: A, because condensation nuclei provide tiny surfaces on which water vapour can begin to condense. The atmosphere may contain water vapour, but forming a stable liquid droplet directly in clean air is difficult because a very small droplet has a high surface-energy requirement. Dust, sea-salt particles, smoke, pollen, and other aerosols can act as nuclei. Water molecules collect around these particles when air becomes sufficiently cool and moist, producing cloud droplets. B is wrong because water vapour is normally present in moist air. C is wrong because clouds do not form only from soil; many atmospheric particles can serve as nuclei. D is wrong because nuclei assist condensation and cloud formation, rather than stopping rain. Memory cue: a nucleus is a “starter surface” for a cloud droplet.
