Why is meteor burning more visible in the mesosphere?
Answer and explanation
Correct answer: Because atmospheric friction produces heat
The governing concept is aerodynamic heating during atmospheric entry. A meteoroid travels at very high speed, and collisions with atmospheric molecules create intense frictional drag and compression heating. In the mesosphere, the air is still dense enough to produce visible heating, while it is high above most clouds and weather. Ozone, freezing hydrogen and surface water vapour do not explain meteor trails. Hence A is correct.
