Solution

Mesosphere Thermosphere

This layer extends to a height of 80 km from the the Earth's surface. This layer extends to a height of 450 km from the Earth's surface.

Temperature decreases with increase in height. Temperature increases with increase in height.

The layer separating mesosphere and stratosphere is called stratopause. The layer separating thermosphere and mesosphere is called mesopause.

Mesosphere lies above stratosphere. Thermosphere lies above mesosphere.
