Which layer of the atmosphere is between the mesosphere and the exosphere? thermosphere troposphere exosphere stratosphere

Thermosphere

Explanation:

The region between the mesosphere and exosphere is called thermosphere.

Mesosphere:

It is present above the stratosphere. In this layer of atmosphere temperature is low because of height. The temperature is about -90 °C.

Thermosphere:

Thermosphere is present above mesoshpere. In this region due to absorption of U.V and X-rays temperature again increase.

The region above 80 Km is also called ionosphere. The high energy radiations knock out the electrons from atoms and make the positive charges called cations.

Exosphere:

This region is present about 500 km of atmosphere. It consist of oxygen and hydrogen.

The correct answer would be the Thermosphere.
