Meteors generally burn up in which atmospheric layer?
Answer and explanation
Correct answer: Mesosphere
The governing concept is the interaction between incoming meteoroids and atmospheric particles. Most meteors become visible and burn in the mesosphere because they collide with enough air molecules there to produce intense frictional heating and ablation. Therefore option A is correct. The troposphere and stratosphere are lower, denser layers, while the exosphere is so thin that it usually causes far fewer collisions and is not the usual region of meteor burning.
