Which source is a proper source of atmospheric dust particles?
Answer and explanation
Correct answer: Desert surfaces and volcanic ash
Wind can lift fine soil and sand from dry desert surfaces, while volcanic eruptions eject ash and other solid fragments into the atmosphere. Both processes therefore provide genuine natural sources of atmospheric dust and aerosols, making option A correct. Evaporation of pure water changes liquid water into vapour and does not create mineral dust. Condensation forms liquid droplets or ice crystals, not dust, and material from Earth’s outer core does not normally enter the atmosphere.
