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).
The mesosphere layer is the coldest layer. You should know that the mesosphere layer extends from the stratopause (at a height of 50 km above the sea level) to the mesopause (at a height of 85 km above the sea level) .The thickness of the mesosphere layer is 35 kilometres.You should know that the temperature in the mesosphere layer decreases with a rate as we go up until it reaches (â 90 degree Celsius) at its top. So, it is called the coldest layer.he thickness of the mesosphere layer is 35 kilometres.
