Concept:Temperature inversion is the reversal of the normal temperature decrease with altitude in the troposphere.
Explanation:Normally, temperature decreases as height increases in the troposphere.
Under normal conditions, warm air rises and cools with altitude.
During a temperature inversion, this normal pattern is reversed.
A layer of warm air becomes trapped above a layer of cooler air near the ground.
Consequently, temperature actually increases with height instead of decreasing.
Option A describes warm air rising over cold air, which is convection and not an inversion.
Option B refers to an isothermal condition, where temperature stays the same with height.
Option C involves horizontal temperature changes and is unrelated to altitude.
Therefore, the correct condition for temperature inversion is an increase in temperature with height.
Answer:D. Temperature increases with height
