Mesosphere
It is so because, some of the meteoroids are of comparatively large size. So when they enter the atmosphere, a big part of them is burnt but still the remaining one enters the atmosphere.
The Earth has an atmosphere around it.The Thermosphere is the top-most layer of the atmosphere.The troposphere is the lowest part of the atmosphere.Unlike Earth,the Moon has no atmosphere.That's why meteoroids don't burn up before they hit the surface.Even though the Earth's atmosphere is immense,sometimes meteoroids get through the atmosphere.

Meteoroids don't enter the earths atmosphere, Meteors do. Meteoroids are the rocks that you find on the ground after a meteor penetrated the atmosphere and made it to the ground.
Meteoroids are small, solid, extraterrestrial bodies that hits the earth's atmosphere.
The mesosphere protects the earth from most meteoroids.
Yes, the mesosphere helps protect Earth from meteoroids by burning up smaller meteoroids as they enter the atmosphere due to friction with gas molecules. This process causes them to disintegrate before reaching the Earth's surface.
We know that there are small meteoroids and dust in space because meteorites (meteoroids that survive the atmosphere and land on Earth) exist, and also because we can see meteoroids as meteors (the light coming from a meteoroid burning up in the atmosphere) in the sky.
