where do meteors come from, what are they made up of and how often do they come down?

Question

really need help people

Answer 1

They made of a soft pumice like material and are made of ice and that material.

Some are made of rock...asteriod apothis is coming near us in a few years.

In 2012 we're screwed

Answer 2

Meteors are small pieces of rocks or metals.You can always see it as a shooting star on a clear moonless night.They are formed due to the breakage of comets,when they pass very close to the sun.So they come from the outer space ,enter our atmosphere and most of them get completely burnt in the atmosphere due to friction.The larger meteors may survive the heat produced by friction and may not be completely burnt.These blazing objects which manage to reach the earth are called meteorites.
Thus a meteor is a relatively small body that has become incandescent because of the heat of friction in passing through the earth's atmosphere.When the earth's orbit crosses the orbit of the comet,these meteors fall on the surface of the earth as a shower.

Answer 3

They are made mostly of silicon, iron, and nickel, but also other elements. Where they come from is kind of a complicated question, some scientists say those elements came from the sun, others say they came from supernovae billions of years ago. There is an astroid belt between mars and jupiter which was thought to have been a planet at one time, but i don't know if they still think that. They come down constantly all day and night, but a lot of them aren't bright enough to be seen, or burn up very very quickly, or are too light to fall fast enough to get hot. Like 99.9% of the matter than comes from space is "dust" and we never see it falling in. I don't know how small they have to get to still be considered a meteor.

Answer 4

meteors are the asteroids which are displaced from their orbits and the asteroids were the rocks which were going to combine to make a planet but it was not created for some reason.
