Expert Answer:

Troposphere is the lowest layer of atmosphere. It extends from earth’s surface to about 16 km. In the weather phenomenon known as thermal inversion, a layer of cooler air is trapped near the ground by a layer of warmer air above. When this occurs, normal air mixing almost ceases and pollutants are trapped in the lower layer.
