Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A phenomenon in which a layer of cooler air is trapped under a layer of warmer air above a city is called:
A
Climate change
B
Global warming
C
Temperature (thermal) fluctuation
D
Temperature (thermal) inversion
Explanation: 

Detailed explanation-1: -Temperature inversion is a meteorological phenomenon that develops when cool air is trapped at the ground under a layer of warm air. There are four types of temperature inversions: A ground inversion occurs most often on clear nights, when the air close to the ground is cooled by radiation.

Detailed explanation-2: -Under normal atmospheric conditions, air is warmer near the ground and colder at higher altitudes. In a temperature inversion, the situation “inverts, ” and cold air at the surface gets trapped under a layer of warmer air.

Detailed explanation-3: -A temperature inversion is a layer in the atmosphere in which air temperature increases with height. An inversion is present in the lower part of a cap. The cap is a layer of relatively warm air aloft (above the inversion).

Detailed explanation-4: -What is an example of temperature inversion? Freezing rain is an example of temperature inversion. This phenomenon develops with a temperature inversion in a cold area because snow melts as it moves through the warm inversion layer.

Detailed explanation-5: -An inversion represents a layer of the atmosphere in which the temperature gets warmer the higher you go. A variety of conditions can cause inversions, but most common in Arizona is the nighttime inversion. This is when a layer of cooler air is trapped near the ground by a layer of warm air above the surface.
