True. The vast majority of meteoroids burn up in the atmosphere, and reach the ground only as dust, after drifting around in the atmosphere for some time. (The stuff you wipe off the top of the TV set? Some of it is probably meteor dust.)

What prevents most asteroids comets and meteoroids from colliding with the earth?
Hopefully, they burn up on entering our atmosphere, due to friction with the air.
What prevents most small meteoroids from hitting Earth's surface?
the o zone
What would happen to most meteoroids when they enter earth's atmosphere?
They disintegrate into dust from the heat.
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.
Are most meteoroids that cause meteors about the size of a pebble?
Smaller than that, even; the size of a grain of rice, or smaller.
Do most the meteoroids burn up the stratosphere?
yes
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.

Which layer of the atmosphere protects Earth's surface from being hit by the most meteoroids?
The mesosphere protects the earth from most meteoroids.
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.
Are most meteoroids smaller than pebbles or bigger than boulders?
Meteoroids are smaller than asteroids; most are smaller than the size of a pebble.
In which atmospheric layer do most meteoroids break up?
in the mesosphere
What layer in the atmosphere has most meteoroids break up?
Usually the troposphere.
What layer of the earth has shooting stars and meteorites?
A meteorite is an object from space that has hit the surface of earth. Therefore you will find them at the bottom of the troposphere. However, you were probably refering to meteors. Most meteors are visible in the lower themosphere or upper troposphere.
What prevents most small meteoroids from hitting Earth's surface?
the o zone
What would happen to most meteoroids when they enter earth's atmosphere?
They disintegrate into dust from the heat.
Which layer of the atmosphere protct earth's surface from being hit by most meteoroids?
ozone layer
