What role can dust particles play in the atmosphere?
Answer and explanation
Correct answer: Acting as condensation nuclei
Dust particles can act as condensation nuclei, which is the governing atmospheric process in this question. Water vapour gathers on their surfaces and, when air cools sufficiently, forms tiny droplets or ice crystals that contribute to clouds and sometimes precipitation. Thus option A is correct. Dust does not completely absorb sunlight, produce oxygen, or permanently raise air pressure; those statements describe effects dust does not normally cause.
