What happens to most meteors when they enter Earth's atmosphere?

Explanation:
When a piece of space debris enters Earth's atmosphere, it moves extremely fast through air. The air in front of it is compressed and heated, and the friction from this rapid interaction raises the meteoroid’s temperature dramatically. That intense heating causes it to glow, vaporize, and shed mass in a process called ablation. Because of this aerodynamic heating, most meteors burn up before they can reach the ground, creating the bright streaks we see as shooting stars. Only a small fraction survive the fiery passage and reach the surface as meteorites.
