Why do meteors usually burn in the mesosphere even though gas density is lower than in the troposphere?
Answer and explanation
Correct answer: High-speed collisions with gas particles produce sufficient heat
The governing process is atmospheric entry heating. A meteor travels at extremely high speed, compressing and strongly disturbing the air in front of it; collisions and the resulting shock layer convert kinetic energy into heat. Even though the mesosphere is less dense than the troposphere, it contains enough particles for intense heating at meteoric speeds. Option A is correct. Rain, ozone pressure, and sea salt do not explain meteor burning.
