Why is the mesophere cold?

Question

Please explain. I read stuff in Wikipedia but it doesnt say why the mesophere is cold or what makes it cold. Thanks

Answer 1

The fall of temperature in the mesosphere is an continuation of a similar trend in the troposphere.This trend is disrupted in the middle layer of stratosphere by the absorption of ultra-violet radiation by the ozone.But for this interruption, the fall of temperature with height would have continued from the surface of the ground to the top of the mesosphere.
