Consider the following statements:
1. Temperature inversion occurs when cold air stays close to the ground preventing warm air from rising.
2. During temperature inversion smoke and dust particles get trapped near the ground making air quality poor.
3. A long winter night with clear skies and still air is an ideal situation for inversion.

How many of the above statements are correct?
(a) Only one
(b) Only two
(c) All three
(d) None

ONLiNE UPSC · Accepted Answer

Temperature inversion occurs when dense cooler air accumulates at the surface blocking the upward movement of warmer air.
During a temperature inversion, pollutants like smoke and dust get trapped beneath the inversion layer leading to poor air quality.
Temperature inversions can last from a few hours to several days depending on various factors like weather conditions and local geography.
