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).
As the mesosphere extends upward above the stratosphere, temperatures decrease. The coldest parts of our atmosphere are located in this layer and can reach â90Â°C. In the forth layer from Earth's surface, the thermosphere, the air is thin, meaning that there are far fewer air molecules. Comments.
