The temperature of the mesosphere decreases from 0°C at the bottom to -90°C at the top.This change in temperature is a result of
A)a decrease in air pressure.
B)low absorption of solar radiation-air molecules emit more energy than they absorb.
C)low air density.
D)all of these

The mesosphere is located above the stratosphere and below the thermosphere. It is characterized by the low absorption of solar radiation, which leads to a decrease in temperature with increasing altitude. Air pressure and density also decrease with altitude, but these factors alone cannot explain the large decrease in temperature observed in the mesosphere. Therefore, choice B is the best answer.

The Temperature of the Mesosphere Decreases from 0°C at the Bottom
