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.
Meteor's come in a range of sizes, from dust-sized which we see as reflected sunlight in the orbital plane of the Solar System (called zodiacal light) to house-sized. When a meteor enters the atmosphere friction causes ablation of its surface (i.e. it burns up). If the meteor is small (fist-sized) it vaporizes before hitting the ground. If larger it survives to impact on the ground, although it will be reduced in size during entry into the atmosphere. About 25 million meteors enter the Earth's atmosphere every day (duck!). Most burn up and about 1 million kilograms of dust per day settles to the Earth's surface.
