What is the main reason for considering atmospheric dust particles important in weather formation?
Answer and explanation
Correct answer: They provide surfaces for water vapour condensation
The governing concept is the formation of condensation nuclei. Water vapour does not usually form cloud droplets efficiently in completely clean air; microscopic dust, salt, smoke, and other aerosol particles provide surfaces on which vapour can condense when air cools to saturation. This supports cloud formation and can influence rainfall, so option D is correct. Dust does not completely dry the air, convert nitrogen into oxygen, or supply energy to the Sun; therefore A, B, and C are incorrect.
