Meteors usually burn up in the mesosphere, in aâ¦ltitude from 75 km  to 100 km in earth atmosphere.as long as the meteor is small enough it burns up in earths atmoshere but rarly they dont burn up and make it though. Meteors burn up when the start coming through the atmosphere.
The third layer is called Mesosphere, a layer that is 70km above the ground. The gases in the Mesosphere are too thin to absorb much of the sun's heat. Although the air is still thick enough to slow down meteorites hurtling into the atmosphere. They burn up, leaving fiery in the night sky. The 4th layer is called Thermosphere, the layer that is at a height of 200km above the Earth's surface. The gases of the Thermosphere are even thinner than those in the Mesosphere, but they absorb Ultraviolet light from the sun.
