Question

In which part of the atmosphere does the temperature decrease as the altitude increases?

A) mesosphere only
B) mesosphere and troposphere
C) stratosphere and mesosphere
D) thermosphere and troposphere

Answer 1

The correct option is A) mesosphere only

Step-by-step explanation:

The solar radiation is not absorbed by the mesosphere of the Earth. Hence, the temperature of the mesosphere decreases as the altitude increases. At the mesopause, the temperature begins to increase with altitude, and this trend continues in the thermosphere.

On the other hand, in the stratosphere, temperature increases with altitude. Hence, other options are not correct.
