The stratosphere and the thermosphere

Explanation:

Stratosphere and thermosphere are the atmospheric layers. The atmospheric layers are varies in temperature due differential absorption of solar radiation. The stratosphere is the second major atmospheric layer, extends up 50 km above the planet's surface. Ozone layer in this layer plays the major role in the thermal regulation by absorbing ultraviolet radiation.

Above mesosphere, the thermosphere is located. The temperature in the thermosphere is very high (600- 2000°F) this is due to the absorption of intense solar radiation.
