Answers
Answer:
Hi ! Let me help u with the answer.
Explanation:
Mesophere is the region of the earth's atmosphere above the stratosphere and below the thermosphere, between about 50 and 80 km in altitude.
Most of these tides and waves start in the troposphere and lower stratosphere, and propagate to the mesosphere. In the mesosphere, gravity-wave amplitudes can become so large that the waves become unstable and dissipate. This dissipation deposits momentum into the mesosphere and largely drives global circulation.
Some material from meteors lingers in the mesosphere, causing this layer to have a relatively high concentration of iron and other metal atoms. Very strange, high altitude clouds called "noctilucent clouds" or "polar mesospheric clouds" sometime form in the mesosphere near the poles.
I hope this answer helps you !!!
