Question

Which group of air pollutants tend to cool the atmosphere because they reflect more sunlight back to space thus reducing incoming solar radiation? A. CFCs. B. ozone enhancers. C. nitrous oxides. D. atmospheric aerosols.

Answer 1

Answer:

D. atmospheric aerosols.

Explanation:

Atmospheric aerosols are tiny particles that float in the air. These particles could be liquid or solid and are usually suspended primarily by direct emission into the atmosphere or secondarily by condensation process.

Atmospheric aerosols have numerous effects on the biotic and abiotic factors of the environment. They alter air quality and impact human health in some cases, they can reduce atmospheric visibility, and they also reduce the amount of radiation that reaches the earth by scattering or reflecting some of the radiations from the sun back into space, leading to cooling of the atmosphere.
