Which atmospheric layer is most affected by the mixing of pollutants released near Earth’s surface?
Answer and explanation
Correct answer: Troposphere
The governing concept is the distribution of pollutants in the lowest part of the atmosphere. The troposphere extends from Earth’s surface upward and contains most atmospheric mass, water vapour, clouds, and weather-related turbulence. These processes mix pollutants released by vehicles, industries, and fires within this layer. The mesosphere, thermosphere, and exosphere are much higher and far too thin to be the main near-surface pollution region, so option A is correct.
