What is the difference between the meteorites from earth and from mars?
Basic Answer:Detailed chemical analysis distinguishes the various type of meteorites and can easily tell the difference between the meteorites found on Earth that originated during the formation of the solar system and those found on Earth which are from Mars. Of the 60,000 known meteorites found on Earth, just over 100 originated on Mars.More Details:We need to get the language right to begin with.Mars Meteorite:If we say a meteorite is from Mars, we mean it actually was part of Mars and was ejected into space by a comet or asteroid collision with Mars. There are just over a hundred Martian Meteorites found on Earth. (The most famous meteorite from Mars is the Allan Hills 84001 found in Antarctica in 1984 and evaluated in 1995 as possibly having fossilized microbes, i.e. evidence of life on Mars. ) A meteorite which is found on Mars is not a Mars Meteorite.Earth Meteorite:Similarly, if we say a meteorite is from Earth, we mean it actually was part of Earth and was ejected into space somehow. These surely exist since there have been major collisions between Earth and large asteroids in the past. We even know that certain special minerals are produced in such collisions. Billions of tiny pieces of these special minerals as well as other rocks have been ejected into space and fallen back to Earth. Even so, we don't call them meteorites since they probably just went up and then down in a short time. Meteorites really need to come in a space rocks colliding with Earth and no such object has ever been identified that was, billions of years ago, part of Earth. So, basically, there are no Meteorites from Earth that have been discovered.Distinctions:The way that a meteorite is determined to have started off on a planet is by chemical analysis, isotopic analysis and by radiometric dating. One can look this up and learn there are very specific groups of meteorites and very well characterized chemical signatures. All planet originated meteorites are in the subgroup SNC (Shergottite, Nakhlite, or Chassignite) of the type Achondrite. Further, these are rarely over a billion years old.
Uranium in meteorites?
In carbonaceous meteorites: cca. 10 parts per billion (as weight) or cca. 1 part per billion (as atoms).
What is the connection between meteorites and comets?
There is no connection, comets for the most part are large frozen blocks, mostly frozen water and they come from beyond Pluto, meteors are large pieces of rock and metal, and meteorites are meteors that reach our atmosphere and are usually quite small by the time they hit earth
What kinds of evidence do geologists use to study the structure of earth?
Meteorites which are sometimes remnants of exploded planets reveal what the inner layers may consist of. Also of use in inferring the structure of Earth are the responses of seismic waves as they travel through the Earth and are recorded by scientific instruments. Mathematical calculations of Earth's density and its relation to our gravitational effects on the surrounding celestial bodies also plays a part in determing composition. And finally, the study of the magnetosphere, the magnetic field around the Earth which blocks harmful solar radiation, reveals the structure and interplay of the inner and outer core.
Are moon fragments part of a moon?
Moon fragments could be part of the moon as well as external bodies that have hit the lunar surface such as asteroids and meteorites.
What protects the earth from small meteorites while the earth's moon is?
The earth's atmosphere protects it from small meteorites - actually the specific part is the mesosphere. When meteorites contact this part of the atmosphere they wither burn up or become very small. I don't understant the "earth's moon is" part, sorry.
Are meteorites part of the solar system?
Yes, meteorites are part of the solar system. They can be part of the asteroid belt. Normally, they are just moving around.

Why are the craters on the moon all perfectly circular?
It can not be because the moon has no atmosphere or gravity....in fact many craters would then have a parabolical shape because all meteorites can not impact with the moon at an exact vertical angle. So why can it be? It is because the theories of the moon being part of a very young earth is simply not true. Earth with it's much stronger gravitational pull should attract far more meteorites away from the moon, had this been the case. Also, the moon, being so close to earth, is protected by the earth from meteorite strikes directly in line with the earth. Earth's gravity would not allow meteorites to hit the moon directly behind it. Missing earth, the meteorites will definitely not impact with the moon directly behind earth. Many craters are on the side of the moon facing earth, so how did these meteorites get past earth to stirke the moon exactly face on? Remember that the moon is in terms of the universe, very close to earth therefore earth is shielding the moon against many many meteorite strikes from directly behind earth itself. Sorry, but I can not answer this question!

What is a meteorites revolution and rotation?
That will vary A LOT, depending on the specific meteorite. Note: Strictly speaking a meteorite is a "meteoroid" that's landed on Earth. If you think of this as a "trick question", the answer is "exactly the same as Earth's". That's because a meteorite is, strictly speaking, part of the Earth!
Were rocks with iron once part of the asteroid belt?
Occasionally they might be, as iron-rich meteorites may have originated as part of asteroids, though not necessarily from between the orbits of Mars and Jupiter. However many Earth rocks contain iron.

How do paleontologists help with evidence of evolution?
Palaeontologists uncover, examine, categorize and publish about fossils. An important part of what we know of the natural history of life on Earth comes from fossil evidence.
