What is the best reason for linking the mesosphere with Earth's natural protection?
Answer and explanation
Correct answer: Many meteors burn in it
The governing concept is the protective role of atmospheric layers. Most meteoroids entering Earth’s atmosphere encounter strong friction and ablation in the mesosphere, causing many of them to heat up and burn before reaching the surface. The ozone layer, not the mesosphere, absorbs harmful ultraviolet radiation; rainfall and radio-wave production are not the relevant reasons. Thus option D is correct.
