Question

Is mesosphere is where most of meteoroids begin to burn?

Answer 1

Meteoroids urn up in mesosphere because there are a lot of gases that cause friction. Friction causes heat, hence meteoroids burn in mesosphere.

Answer 2

The mesosphere is 22 miles (35 kilometers) thick. ... Those meteors are burning up in the mesosphere. The meteors make it through the exosphere and thermosphere without much trouble because those layers don't have much air. But when they hit the mesosphere, there are enough gases to cause friction and create heat.
