If dust and salt particles are low in air what difficulty may occur in cloud droplet formation?
Answer and explanation
Correct answer: Fewer condensation nuclei will be available
Cloud droplets usually form when water vapour condenses on tiny particles called condensation nuclei. Dust, sea-salt particles and other aerosols provide surfaces on which water can collect. If these particles are scarce, fewer suitable surfaces are available, so droplet formation becomes more difficult, although cooling and high humidity may still permit condensation. Thus option C is correct; the other choices describe unrelated changes.
