Question
An inversion layer is a layer in the atmosphere in which the air is _________. Inversion layers are important because _______. Select one: A. Colder than the air below: they trap pollutants below the inversion thereby increasing concentrations B. Warmer than the air below: they speed up chemical reactions that form air pollution. C. Warmer than the air below: they trap pollutants below the inversion thereby increasing concentrations D. Colder than the air below: they speed up chemical reactions that form air pollution.Explanation / Answer
Answer : C
Temperature inversion, a reversal of the normal behaviour of temperature in the troposphere (the region of the atmosphere nearest the Earth's surface), in which a layer of cool air at the surface is overlain by a layer of warmer air. (Under normal conditions air temperature usually decreases with height.)
