Which statement below best describes the temperature of the atmosphere at various altitudes? a.) the mesosphere has a lower temperature than the thermosphere. b.) the mesosphere has a higher temperature than the thermosphere. c.) the temperature of the mesosphere is the same as the thermosphere. d.) the altitude has no impact on the temperature of the atmospheric layers.

A). The mesophere has a lower temperature than the thermosphere.

Explanation:

At the mesophere,  the temperature decreases with height, reaching a minimum of about -90°C at the "mesopause".  As we rise up in the mesophere, the temperture becomes colder and colder. Above the mesophere is the thermosphere, where variations in the sun's energy have a powerful influence on both the height of the top layer of the thermosphere and the temperature within it. Because of this, temperatures of the upper layer of thermosphere can vary from 500° C (932° F) to 2,000° C (3,632° F) or higher.
