Which statement below about atmospheric layers is correct?
a. the mesosphere is located from about 10 to 50 km and has an increasing temperature with altitude.
b. the troposphere is located from about 10 to 50 km and has an increasing temperature with altitude.
c. the mesosphere contains a protective layer of ozone that absorbs ultraviolet radiation from the sun.
d. the stratosphere is located from ground level to about 10 km and has a decreasing temperature with altitude.
e. the mesosphere has a temperature that decreases to about -90c at its highest altitude of about 80 km.

B. The troposphere starts from 10 and has temperature increasing with altitude.

Explanation:

There is an increase of temperature from the ground as this layer extends from 10 to 50 kilometers, and due to the temperature inversions that occur at the tropopause which is a region of mixing. After this zone, the mixing stops and the layers of air become stable and hence, there is no further major disturbance in the following layers except the changes in the chemical and physical properties.
