Why does the size of atmospheric particles change their environmental impact?
Answer and explanation
Correct answer: Because large and small particles differ in travel distance, deposition and respiratory entry
The governing concept is size-dependent aerosol behaviour. Fine particles can remain suspended longer, travel farther and penetrate more deeply into the respiratory system, while larger particles settle faster and are often trapped earlier in the nose or throat. Size also affects light scattering and cloud interactions. Option A is correct; the other choices deny these established physical and health differences.
