Why do meteors burn in the mesosphere even though atmospheric temperature is very low there?
Answer and explanation
Correct answer: Their high speed creates frictional heating through collisions with air particles
The temperature of the surrounding mesosphere is not the same as the heat generated on a rapidly moving meteor. As a meteor enters the atmosphere at very high speed, it compresses and collides strongly with air molecules; this produces intense aerodynamic heating and ablates its surface. Thus option A is correct. Seawater, rainfall, and ozone do not provide the required mechanism for meteor burning.
