Do most meteoroids burn up in the ionosphere?

Most meteoroids do not burn up in the ionosphere; instead, they typically enter the Earth's atmosphere from space and ignite at altitudes ranging from about 75 to 100 kilometers above the surface. As they travel through the atmosphere, the intense friction with air molecules causes them to heat up and produce visible trails of light, known as meteors. The ionosphere, which is a layer of the atmosphere that exists at higher altitudes, primarily influences radio wave propagation rather than serving as the main site for meteoroid incineration. Therefore, while meteoroids can interact with the ionosphere, they predominantly burn up in the lower atmospheric layers.
