What is a common importance of water vapour and dust particles among atmospheric elements?
Answer and explanation
Correct answer: Both can play a role in cloud formation
Cloud formation requires moist air and suitable surfaces on which condensation can begin. Water vapour supplies the moisture that changes into tiny droplets or ice crystals when air cools. Dust particles can act as condensation nuclei, providing surfaces on which water vapour gathers. Consequently option A is correct. Neither substance is an inert gas, a form of nitrogen, or a material forming Earth’s core.
