Why are aerosols among atmospheric elements studied according to age and size?
Answer and explanation
Correct answer: Because size and residence time change their transport, deposition and effects
An aerosol is a suspended solid or liquid particle, not a permanent gas. Particle size affects settling speed, ability to remain airborne, distance of transport and depth of penetration into the respiratory system. Chemical ageing can also alter its reactivity and climate effect. Thus option A is correct; B, C and D contradict these physical and chemical properties.
