What layer of earth atmosphere blocks meteors from hitting the earth?

All layers of the atmosphere. Depending on the angle at which a meteoroid enters the earth's atmosphere, it follows a trajectory towards the earth's surface. While doing so, aerodynamic friction heats it up and it becomes a meteor. It may fragment and burn up entirely but otherwise, it will remain a meteor all the way down to the earth's surface and, when it strikes, it will become a meteorite.

When those particles enter the Earth's atmosphere, their high speed causes friction, which heats them to incandescence, or "white hot". The glowing streak of the meteor is the meteor burning up high in the air. Only fairly large objects survive this blazing entry into the atmosphere to become "meteorites".
Many meteors burn up as they whiz through the atmosphere. that is why they look like shooting stars because they r on fire. But a lot hit the ground, and are called meteorites. Some have been so huge that they have left very large craters.

They are slowed down as much as they are burned up. The ones that make great impacts on Earth were ones that were so large as meteoroids, that when they entered the Earth's atmosphere, barely any material was burned up. Meteors/Meteoroids add several tons of weight to Earth every day.
So in recapitulation, Meteors are mostly burned up in the Thermosphere since it is the hottest layer and the largest. The mesosphere would "slow it down" the most but this would only make the impact crater that the meteorite leaves (if any at all) shallower.

The Thermosphere is the outer most layer of the Earth's atmosphere. The lower boundary starts approximately 48 miles up and then just extends into planetary space where it blends with the solar wind. The concentration of gas particles is so low that it essentially does nothing to impede any meteors of a sizable nature.

How do meteors orbit the sun?
Meteors do not orbit the Sun. Meteors are to be found/seen in the Earth's atmosphere burning up. Before they enter the Earths atmosphere they are called meteoroids and if they land on Earth they are called meteorites.
What is the difference between comet and meteors?
Comets are flying bits of rock that don't enter the earth's atmosphere and meteors are flying bits of iron stone or stony iron. Also meteors do enter the earth's atmosphere.
Why is mesosphere important?
The mesosphere is important because metioroids burn up in this portion of the atmosphere stoping them from going to the earth.
What happens when a object pass the solar system and enters earth's atmosphere?
Usually meteors that collide with the earth's atmosphere are burned upon entry. The become what is known as "shooting stars".
Why don't really large meteors hit earth?
There are much less "really large" meteors than small ones. However, Earth has been hit in the past by such meteors, and it is likely that it will be hit again at some moment. For example, about 65 million years ago, a meteor impact resulted in the elimination of dinosaurs (and in fact of many species).
Why do meteors turn to a ball of fire when hitting the axis?
Meteors become glowing hot by extreme friction from passing through the Earth's atmosphere at high speed.
Where at in the atmosphere are meteors located?
earth's upper atmosphere.
What protect earth from meteors?
Its atmosphere.

Why do meteors shine?
Meteors shine because of gases that burn in Earth's atmosphere. The friction caused by traveling in the atmosphere ignites the gases.
Why can't astronomers use a telescope to study the entire surface of the moon?
The moon has no atmosphere, so there is nothing there to burn up the dust and dirt and ice and rocks, turning them into meteors, as happens on Earth. Meteors seen on Earth are so brief and fast and enclosed by the atmosphere, and so far from the Moon that you would not see Earth's meteors from the Moon.The moon has no atmosphere, so there is nothing there to burn up the dust and dirt and ice and rocks, turning them into meteors, as happens on Earth.

Can meteors get through the atmosphere?
Small meteors may burn up as they travel through the atmosphere, but larger ones do get through the atmosphere and land on the surface of the Earth.
What is the possiblity of a meteor hitting earth?
Very high - damn one just did. Meteors hit the Earth almost every second. Very few manage to penetrate the Earths atmosphere and become meteorites.
most meteors that fall into the Earth's atmosphere burn up before reaching the ground. Why is this?
They are hitting air molecules at a high speed and breaking them apart, which produces a lot of heat.
