Answer to Question #86469 in Chemistry for Neeraj Yadav

Question

What is mesopause and which layer of atmosphere is just above it?Give appropriate diagram indicating all the layers of atmosphere.

Answer 1

The mesopause is the layer of the atmosphere separating the mesosphere and the thermosphere. On Earth, it is located at an altitude of 80-90 km above sea level. There is a temperature minimum in the mesopause, which is about −100 ° C. The mesopause coincides with the lower limit of the region of active absorption of X-ray and the shortest-wave ultraviolet radiation of the Sun. The thermosphere is just above the mesopause.
