Question

Quizplus · Accepted Answer

Temperature inversions occur when the surface temperature is lower than warmer overlying air. This often happens in the early morning or during the night when the ground cools rapidly, but the air above remains warmer. This can cause the air pollutants to get trapped close to the ground which can lead to severe air pollution problems.
