Which statement correctly gives natural and human-made aerosol sources?
Answer and explanation
Correct answer: Volcanic ash is natural and industrial smoke is human-made
An aerosol is a suspension of fine solid particles or liquid droplets in air. Volcanic eruptions release ash naturally, whereas industrial activity can emit smoke, soot, and other particles through combustion and manufacturing. Therefore option A correctly pairs one natural source with one human-made source. Sea tides are natural, gases such as nitrogen and argon are not aerosols in this sense, and ozone and oxygen are gases rather than ash or dust particles.
