How can the absence of atmospheric dust particles affect rainfall formation?
Answer and explanation
Correct answer: Droplet formation may become difficult due to fewer nuclei for condensation
The governing concept is condensation nuclei. Water vapour usually condenses more readily on tiny particles such as dust, salt, or smoke. If such particles are scarce, fewer suitable surfaces are available, so cloud droplets may form less easily and rainfall formation can be reduced or delayed. Option B concerns oxygen concentration, while C and D describe processes unrelated to condensation.
