When meteoroids enter the earths atmosphere they become hot and before they hit the earths surface?

Yes. Meteoroids are traveling AT LEAST 25,000 MPH, and sometimes far faster; some have been tracked at 125K MPH. They run into the atmosphere and at that speed, the air CANNOT get out of the way. The super-thin air is compressed to the density of water or thicker, which heats the meteoroid to incandescence, which means "glowing hot".
Depending on the structure and composition of the meteoroid, sometimes they melt, sometimes they vaporize, and sometimes they explode. Sometimes, fragments of the meteoroid survives to hit the Earth's surface, when we call them "meteorites".

Why do all planets with and without atmospheres collide with meteoroids?
All planets, both with and without atmospheres, encounter meteoroids. If the planet has an atmosphere then those meteoroids will burn up long before reaching the surface. Those without atmospheres do not have such protection and so the meteoroids strike the surface directly.
Are Meteoroids small pieces of space debris?
Yes, meteoroids are basically small pieces space debris that are considerably smaller than asteroids. They're so small that many of them simply burn up in the atmosphere before ever reaching the surface.
Where are asteriods located?
In The Asteroid Belt
What is a large rock in outer space called?
... compresses the air in front and around it so that the air glows and at night you see a "shooting star" - a meteor. If it impacts the ground before evaporating, it is a bolide and may leave a mineral remnant called a meteorite.
Is Mars sandy?
We do not no for sure what Jupiter's surface is like, or if it has a surface at all. It may have a rocky core or may just be a ball of gas. Jupiter is covered completely by its atmosphere and we cannot see past it. A satellite was plumeted into Jupiter but it burned up in the atmosphere before we learned anything about its surface.

How does the atmosphere protect us from meteoroids?
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.

Why do meteoroids burn up as they approach earth but not the moon?
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.
Why do meteoroids become fireballs as they approach the earth?
As a meteors enters the earth's atmosphere, the frictional heat is so intense it begins to catch fire, which is why must meteors burn-up before they hit our planet. Meteors are called meteors until they hit the earth's surface, then they are called meteorites!!
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.
Where would you most likely find a meteor?
Meteors are pieces of rock glowing hot in the atmosphere. Before they hit the air, they were meteoroids. When they his the ground they are meteorites. Meteors are only found in the atmosphere, moving at incredible speeds.
What is a normally very small solid objects that traverse space and usually are turned up before reaching earth?
While still in space, we call them meteoroids. As they pass through the atmosphere, the glowing trail is called a "meteor". If they survive and strike the Earth's surface, we call them "meteorites".
What is the distance of a meteoroid?
A meteoroid is a rock that is out in space. It can be any distance from the earth. Most of the meteoroids in the solar system are in the asteroid belt, between the orbit of Mars and the orbit of Jupiter. The closest meteoroids in the asteroid belt are about 100 million kilometers (62 million miles) from the earth. The farthest meteoroids in the asteroid belt are about 800 million kilometers (500 million miles) from the earth. The strong gravity of Jupiter can move some of these meteoroids out of their orbits and send them closer to the earth, so a few meteoroids run into the earth's atmosphere every day. Most meteoroids burn up in the earth's atmosphere before getting to the ground, so they hardly ever do any damage.
What meteors are called before they visit the earth?
Meteors are called meteoroids before they enter Earth's atmosphere. Meteoroids are small pieces of rock or metal that orbit the Sun. When they enter Earth's atmosphere, they heat up due to friction and create a bright streak of light called a meteor or shooting star. If a meteoroid survives its trip through Earth's atmosphere and hits the ground, it is called a meteorite. There are different types of meteoroids, depending on their size and composition. The smallest meteoroids are called micrometeoroids. They are so small that they burn up completely in Earth's atmosphere and are never seen. Mesometeoroids are larger than micrometeoroids, but they are still too small to survive their trip through Earth's atmosphere. They break up into smaller pieces and burn up in the atmosphere. The largest meteoroids are called asteroids. Asteroids are large enough to survive their trip through Earth's atmosphere and hit the ground. When an asteroid hits the ground, it is called an impact. Impacts can cause a lot of damage, depending on the size of the asteroid. The most famous impact in history is the Chicxulub impact, which occurred 66 million years ago. The Chicxulub impact is thought to have caused the extinction of the dinosaurs. Meteors are a beautiful and fascinating sight. They are a reminder of the vastness of space and the many objects that orbit the Sun.
