Because it comes from other planets and earth is approx the same age as the other planets so they work it out bye the dust and how hot it is I think.
No,they could destroy earth but can provide usefull information from outerspace e.g. temperatures..
Meteors travels through earth. While the meteors travel towards the earth they go around the orbit.
Yes, meteors do fall very quickly to Earth.
because with out it meteors would hit Earth because the mesosphere kills the meteors.
No quantity of meteors could destroy the Earth. Could meteors kill all, or even most, LIFE on the Earth? Yes, they could. They almost have, several times in the past 4 billion years. If it were large enough, it would take only one to do the job. We do not, at present, know if there are any large meteoroids or asteroids that are on a collision course to Earth. But it seems likely that within the next 50 years, we will have sufficiently advanced technology to prevent something like this from happening.
They do fall on the Earth.
No, meteors are not extinct. Meteors are commonly seen in the Earth's atmosphere as shooting stars when they burn up upon entry. They are remnants of debris from space that enter the Earth's atmosphere.
Not all meteors impact the surface of the earth. Many burn up in the atmosphere prior to impact. The majority of meteors that do reach the earth's surface usually impact desolate regions.
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!!
Weathering and meteors.
Its atmosphere.
Meteors do not just disappear. Meteors either land somewhere on Earth out of site or they just burn up in the atmosphere.
