Which of the following statements properly describes the cause of a temperature inversion or its effects?

a) temperature inversions are caused by the rising air of convection currents.
b) temperature inversions can trap air pollution in one place for many days.
c) temperature inversions are the main cause of cold fronts.
d) temperature inversions typically happen in open places as weather fronts move through.

Temperature inversions can trap air pollution in one place for many days.

Explanation:

Temperature inversion behaves contrary to the normal behavior of temperature in the atmosphere. When this occurs, air is warmer above a layer of cool air, which would normally be the opposite. This can trap pollution in one place for a long period of time.  

Because of this limited movement of air, temperature inversions are important for forming clouds and rainfall. Therefore, in locations, where there is a low level of temperature inversion, precipitation is greatly affected.
