What is the correct reason for considering the mesosphere an effective barrier for meteors?
Answer and explanation
Correct answer: High-speed friction with air particles produces heat
Most meteors that enter the atmosphere encounter enough gas molecules in the mesosphere to experience strong collisions and aerodynamic heating. Their very high speed converts motion energy into heat through friction and compression, so many glow and ablate before reaching the surface. Thus C is correct. Water vapour does not dissolve them, ozone does not push them into space, and mesospheric pressure is far below sea-level pressure.
