Air friction. Pushing through the air at the speed of a falling meteorite creates lots of heat. Smaller meteoroids simply burn up before they reach the surface.
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.
The atmosphere completely protects us from meteoroids. The pressure of atmosphere causes them to explode.
Meteroroids enter earth's atmosphere. They are broken by mesosphere.
The stratosphere and the mesosphere protect you from harmful ultraviolet radiation and most meteoroids. The stratosphere contains the ozone layer, which absorbs and scatters the sun's UV radiation. The mesosphere helps burn up most meteoroids before they can reach the Earth's surface.

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.
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.

The atmosphere protects us from meteorite impacts. When a meteorite enters Earth's atmosphere, it burns up due to friction with the air, preventing it from reaching the Earth's surface and causing damage.
