The stratopause is the level of the atmosphere which is the boundary between the stratosphere and the mesosphere. In the stratosphere the temperature increases with altitude, and the stratopause is the section where a maximum in the temperature occurs. Layers of Atmosphere (NOAA) The Earths atmosphere is a layer of gases surrounding the planet Earth and retained by the Earths gravity. ... The stratosphere is a layer of Earths atmosphere that is stratified in temperature, with warmer layers higher up and cooler layers farther down. ... The mesosphere (from the Greek words mesos = middle and sphaira = ball) is the layer of the Earths atmosphere that is directly above the stratosphere and directly below the thermosphere. ... Temperature is the physical property of a system which underlies the common notions of hot and cold; the material with the higher temperature is said to be hotter. ... Altitude is the elevation of an object from a known level or datum, called zero level. ...

This not only occurs on Earth, but on other planets with an atmosphere as well. A planet in common parlance is a large object in orbit around a star that is not a star itself. ... Atmosphere is the general name for a layer of gases that may surround a material body of sufficient mass. ...

On Earth, the stratopause is generally considered to be located at an altitude of 50 km. The atmospheric pressure is around 1/1000th of the pressure at sea level. Earth, also known as Terra, and (mostly in the 19th century) Tellus, is the third-closest planet to the Sun. ... A kilometre (American spelling: kilometer), symbol: km is a unit of length in the metric system equal to 1000 metres (from the Greek words χίλια (khilia) = thousand and μέτρο (metro) = count/measure). ... Pressure (symbol: p) is the force per unit area acting on a surface in a direction perpendicular to that surface. ... For considerations of sea level change, in particular rise associated with possible global warming, see sea level rise. ...
