Question

A temperature inversion occurs when ____.

Answer 1

Answer:

Option (3)

Explanation:

The temperature inversion is defined as the condition where the atmospheric temperature increases with respect to height. Normally, the temperature decrease with the height. A stable warm air overlays a colder air at higher elevations, during a temperature inversion condition. This inversion of temperature can also block the pollutants that rises from the lower atmospheric layers. It is because the  warm air that is present above the cooler air does not allow the trapping and merging of the substances.

Thus, the correct answer is option (3).
