A temperature inversion can adversely affect air quality and is characterized by: . 1. inverted air masses with particulate held at altitude 2. a layer of cold air forming above warmer air 3. air masses with inverted primary and secondary pollutants 4. a layer of warm air forming above colder air

4. a layer of warm air forming above colder air

Explanation:

A substance with a higher temperature is usually characterized by it being hotter at the bottom than an at the top. This is because heat is lost more on the surface.

However there is a problem when there is temperature inversion which means the warm air forms over the cold air instead of the opposite which is more ideal. This affects the quality of the air negatively.

these include the fossil fuels, oil, natural gas, and coal and nuclear energy. hope this ! ^.^
