Question 2

The region of relatively unstable air that extends from the surface to the base of an inversion is referred to as the____________________.​

Accepted Answer

mixing layer​

Question 3

Explain the role wind plays in air pollution.

Accepted Answer

Wind speed plays a role in diluting pollution.When vast quantities of pollutants are spewed into the air,the wind speed determines how quickly the pollutants mix with the surrounding air and,of course,how fast they move away from their source.Strong winds tend to lower the concentration of pollutants by spreading them apart as they move downstream.This process of spreading is called dispersion.Moreover,the stronger the wind,the more turbulent the air.Turbulent air produces swirling eddies that dilute the pollutants by mixing them with the cleaner surrounding air.Hence,when the wind dies down,pollutants are not readily dispersed,and they tend to become more concentrated.
