The mesosphere (/ Ë m É s oÊ s f ÉªÉr /; from Greek mesos middle and sphaira sphere) is the layer of the Earth's atmosphere that is directly above the stratosphere and directly below the mesopause. In the mesosphere, temperature decreases as the altitude increases. The upper boundary of the mesosphere is the mesopause, which can be the coldest naturally occurring place on Earth[citation needed] with temperatures below â143 Â°C (â225 Â°F; 130 K).
(3) In the mesosphere, the air is relatively mixed together, so the temperature decreases with altitude. The atmosphere reaches its coldest temperature of around -90Â°C in the mesosphere. This is also the layer in which a lot of meteors burn up while entering the Earth's atmosphere.(4) The thermosphere is the fourth layer of the Earth's atmosphere.The air is really thin in the thermosphere.A small change in energy can cause a large change in temperature. That's why the temperature is very sensitive to solar activity.4) The thermosphere is the fourth layer of the Earth's atmosphere. The air is really thin in the thermosphere.
