How many tons of meteors enter Earths atmosphere every day?
100 ton/day (NASA)
Why is the earths surface not covered by the same impact craters?
First, we have a nice thick atmosphere that deals with many meteors. Secondly, weathering and erosion erase the marks fairly quickly.
Why doesn't the Earth have as many craters as the moon?
The Earth has a atmosphere that shields meteors from hitting Earth and creating craters. The moon has no atmosphere, so meteors hit it often, creating craters.If the earth had no atmosphere where many small meteors would vaporize , or there was no wind or rain or tectonic plate movement, and other geological forces that would eventually cover up such impact sites, and of course no seas, or plant life then earth woulld ovbiously have many more craters than the moon as it's a bigger target. There are well over 100 known sites on earth and more deemed as probable.Because the moon has no atmosphere, it has no protection from meteors, asteroids or meteorites. The last layer in earths atmosphere protects us from that. So that's why earth doesn't have craters.The earth's atmosphere (air), through friction, burns up most of the many meteors that fall to earth. The moon has no atmosphere.The Earth has an atmosphere that burns up many of the items. It has to be pretty big to make it to the surface. And the Earth has weather, which erodes and erases the evidence of many of the strikes that the Earth has had.
How many miles before a rocket passes through the earths atmosphere?
250 miles before it crosses the atmosphere
Why can elements be produce in the sun but not in the earths atmosphere?
Many elements only form through high temperatures and pressures... both of which are present int the Sun - but not in the Earth's atmosphere.

How many miles away is a meteor?
All shooting stars or meteors occur within the atmosphere of the Earth, predominately the mesosphere, which means they occur within 50 -> 120km of the Earths surface.
Do meteors go beyond Jupiter?
Most meteors are sand grain sized objects that had been ejected from comets as they followed around their highly elliptical orbits. As most of these comets have orbits that extend beyond the orbit of Jupiter at their aphelion, then yes most of these sand grains that become meteors when they enter earth's atmosphere have been beyond the orbit of Jupiter. However they are not actually meteors until they enter earth's atmosphere, so while they are actually meteors they are nowhere near Jupiter. Many larger meteors were pieces of asteroids. The vast majority of asteroids orbit between Mars and Jupiter and thus have never been even near Jupiter, and definitely not beyond Jupiter's orbit.

Can asteroids and comets still bombard your planet - earth?
yes, many objects enter earths atmosphere everyday but are burnt up before they make it to the ground.
How many layers dose the earths atmosphere have?
6
How many meteors hit earth in a year?
Many, many thousands. Most are very small and burn up in the atmosphere.
How does solar radiation leave earths atmosphere?
It is radiated by many of the gases in the lower atmosphere.
Does only the moon have craters?
No, Earth has some craters, but not as many because Earth has an atmosphere to destroy or smallen meteors, but the moon does not, so it is hit by meteors more3 often.
Do all meteors impact on Earth's surface?
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.
Why do many meteors never make it to the earth's surface?
The Earth has a thick atmosphere which burns them up via friction.
