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.

Are there meteorites on mars?

Yes. The thin atmosphere of Mars and low rates of weathering means that there are probably more intact meteorites on Mars than on Earth.


How do martain meteorites arrive on earth?

Martian meteorites arrive on Earth through the impact of large asteroids or comets on the surface of Mars. These impacts can eject rocks and debris from Mars' surface, some of which eventually make their way to Earth as meteorites. Scientists can study these Martian meteorites to learn more about conditions on Mars and its history.

Difference between Mars and earth?

Mars is a cold, dry planet with a thin atmosphere, while Earth has a moderate climate, liquid water, and a thick atmosphere. Earth has a diverse range of life forms, while Mars has no known life. The length of a day on Mars is slightly longer than a day on Earth.


Are there meteorites on mars that have hit it?

Yes, there are meteorites on Mars that have hit the planet's surface. These meteorites are pieces of rock or metal from space that have traveled through space before crashing onto Mars. They provide valuable information about Mars' geology and history.


Some meteorites that fell on Earth have been identified as having come from what other planet?

Mars. Some meteorites, known as Martian meteorites, have been identified as originating from Mars. These meteorites carry unique characteristics that link them to Mars, such as gas trapped within their mineral structures that matches the Martian atmosphere.


Has Any PhysicAl Rocks or dust been retreived from mars to earth?

Nothing physical has yet been sent from Mars, although there have been a few meteorites from Mars that have landed on earth.


What is these thing that make up a belt between mars and Jupiter?

Meteorites formation.


How did meteors from Mars arrive on Earth?

Meteors from Mars arrive on Earth when an impact on Mars causes fragments of rocks to be ejected into space. Some of these rocks may eventually cross paths with Earth's orbit and enter our atmosphere as meteorites. Through analysis of the composition and isotopic signatures of these meteorites, scientists can infer that they originated from Mars.


What type of rock is mostly in Martian meteorites?

The most common type of rock found in Martian meteorites is basalt. These meteorites are believed to originate from volcanic activity on Mars, which produced basalts similar to those found on Earth. Scientists study these meteorites to learn more about the geological history and composition of Mars.


What planet has craters made by meteorites?

Mercury, Venus, Earth, and Mars all have impact craters.


How did metors from mars arrive on earth?

Martian meteorites were blasted of of Mars by enormous asteroid impacts and ended up orbiting the sun. Some of them eventually intersected Earth's orbit.
