in which layer of the atmosphere do meteors burn up before impacting earth
Meteoroid A meteor, known colloquially as a "shooting star" or "falling star", is the visible passage of a glowing meteoroid, micrometeoroid, comet or asteroid through Earth's atmosphere, after being heated to incandescence by collisions with air molecules in the upper atmosphere,[9][22][23] creating a streak of light via its rapid motion and sometimes also by shedding glowing material in its wake. Although a meteor may seem to be a few thousand feet from the Earth,[24] meteors typically occur in the mesosphere at altitudes from 76 to 100 km (47 to 62 mi).[25] The root word meteor comes from the Greek meteōros, meaning "high in the air".[22]
