Concept:Temperature inversion is a reversal of the normal temperature decrease in the troposphere. In this condition, temperature increases with height instead of decreasing.Explanation:Normally, air temperature drops as altitude increases in the troposphere. The lapse rate is about 1°C per 165 metres. In temperature inversion, a layer of cool air stays near the surface while a warmer layer sits above it. This causes temperature to rise with height, opposite to the usual pattern. The question asks for the meaning of "inversion of temperature". The term "inversion" refers to this reversal. So, instead of cooling with height, we get warming with height.Answer:Increase of temperature with height (Option B).
