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.
Most meteors burn up in the mesosphere. Unlike the stratosphere, temperatures once again grow colder as you rise up through the mesosphere. The coldest temperatures in Earth's atmosphere, about -90Â° C (-130Â° F), are found near the top of this layer. The air in the mesosphere is far too thin to breathe; air pressure at the bottom of the layer is well below 1% of the pressure at sea level, and continues dropping as you go higher. Thermosphere
