Why are dust and salt particles useful in cloud formation?
Answer and explanation
Correct answer: They act as condensation nuclei
Cloud formation requires water vapour to change into tiny liquid droplets or ice crystals. Dust and salt particles provide surfaces called condensation nuclei, around which water vapour can condense when the air cools sufficiently. Therefore, option A is correct. These particles do not create the Sun, rotate Earth or remove atmospheric oxygen; those choices are unrelated to condensation.
