Question

Which has the highest temperature between mesosphere and ozonosphere ? Please tell...​

Answer 1

The mesosphere lies above the stratosphere and extends to an altitude of about 85 km (Ahrens 13). This is layer is often referred to as the cold layer, as the lowest readings in the atmosphere are found here. Temperature decreases with height, reaching a minimum average value of -90 ºC at the top of the layer.

Answer 2

$\large{ \underline{ \underline{ \sf{ANSWER - }}}}$

Temperature here decreases with height, so within the mesosphere it is warmest at its lowest level (−5°C, or 23°F), and becomes coldest at its highest level (−80°C, or −112°F). Depending on latitude and season, temperatures in the upper mesosphere can be as low as −140°C (−220°F)
