Does this stone come from space or a volcano? 20

Not space. Everything in outer space passes through the atmosphere and comes to Earth, and it has to be burned violently, and the surface is generally dark colors such as black. You're not.

Breccia sandstone, breccia grinding roundness is good, the composition of breccia can be limestone, sandstone, quartzite and so on.

This is one of the most common and common stones.

Volcanoes, definitely not in space.

The composition must be checked before it can be finalized.

Martian stone is not necessarily, not to come to the earth, the real Martian stone, I don't understand! Please guide.

How can there be stones on Mars on Earth? The fact that you can see the rocks on Mars on Earth is enough to show that your abilities have surpassed those of the scientific community! As far as I know, there are no Martian rocks in the world, and although the United States has landed on Mars many times, it has not brought back any Martian sample rocks so far, which may be the reason why I have seen too little, so I think there are no Martian rocks on Earth.

Perhaps the subject is asking how there are meteorites on Mars on Earth? Mars is one of the closest terrestrial planets to Earth and one of the stars with the fewest meteorites. Everyone knows that the vast majority of meteorites come from the asteroid belt between Jupiter and Mars in the solar system, and a small number come from the Moon and Mars.

Meteorites landing on Earth are related to distance and gravity, and not any star that burns the Qiyang system will have a meteorite fall to the Earth. In particular, four of the eight gaseous planets are not in a condition to form meteorites at all. The other four terrestrial planets, except for Mars, although the other three are rock structures, are affected by the distance and gravity of other stars, and there is basically no hope of seeing their landing meteorites on Earth.

The mass of Mars is much smaller than that of the Earth, and the gravitational force is weaker than the Earth's gravity, and when other asteroids collide with Mars, the Martian rock mass that flies out of the Martian surface due to the impact of small stars will be captured by the Earth's gravity and become a Martian meteorite landing on the Earth, so we will have the opportunity to see the appearance of Martian meteorites on the Earth. The Martian rock mass that landed on the Earth is called a meteorite after being baptized in the atmosphere, not a Martian stone.

There are Martian stones on Earth, and this kind of stone is called Martian meteorite. Martian meteorites are formed on the planet Mars, and the composition and isotopes of Martian meteorites are almost the same as all stones on Mars.

How the Martian meteorite came to Earth.

However, because the stones on Mars are ejected from Mars by an asteroid or comet, they fall to the rocks on the Earth through the gravitational force of the Earth. As of March 3, 2014, more than 60,000 meteorites have been found on Earth, but only 132 have been confirmed to be from Mars. These meteorites are thought to have come from Mars because they have a similar elemental and isotopic composition to the rocks and gases analyzed by NASA rover Curiosity on Mars.

There are real stones from Mars on Earth, but very few. Because Mars sometimes sheds stones and falls directly to the surface of the Earth.

Stones from Mars do not exist on Earth. No scientists have confirmed the existence of stones from Mars on Earth, so they do not exist.

There are really a lot of stones from Mars on the earth, because a large number of meteorites pass through the atmosphere every day and come to the earth, and they may be the stones that fell from Mars.

One theory: usually there are large asteroids or comets and other celestial bodies hit Mars, and the strong impact force makes some rocks on the surface of Mars splash into space, because the speed can get rid of the gravitational pull of Mars, then these rocks will wander forward in space, and when they come to the vicinity of the earth, they will be captured by the earth and not rubbed in the earth's atmosphere, so they will become meteorites from Mars.

There is also a theory that there is an asteroid belt between Mars and Jupiter, and there are many asteroids, estimated to be close to a million, which makes Mars more vulnerable to asteroid impacts.

When Mars is hit by a large asteroid, the rocks or dust that are stirred up will normally fall on Mars. Because the atmosphere of Mars is very thin, some debris will be knocked into the space outside the Martian atmosphere, and get rid of the gravitational pull of Mars, fly in the direction of the Earth, and enter the Earth's atmosphere, while the larger fragments will reach the ground after the baptism of fire in the Earth's atmosphere, thus forming meteorites.

No one has ever seen a stone on Mars, so how can they know that it is a stone from Mars.

The meteorite you see is that.

The radius of Mars is half that of Earth, and the mass of Mars is one-ninth of the mass of Earth.

Acceleration of the planet's surface gravity g g r 2g fire g ground (m fire m ground) (r fire 2 r ground 2) (1 9) (1 2) 2 4 9

So g fire 4g earth 9 4* 9 m s 2, so 100 tons of stone on Mars lifting force f1 = mg fire = 43600n on Earth, f2 = mg earth = 980000n

Yes. What is the formation of Huoqing Mountain? Below the surface, the deeper you go, the warmer it gets. At a depth of about 32 kilometers above the surface, the temperature is high enough to melt most of the rock.

The rock expands when it melts, requiring more space. In some parts of the world, mountains are rising. The pressure is decreasing beneath these rising mountains, and a reservoir of lava (also called "magma") may be forming underneath these mountains.

This substance rises along the cracks caused by the uplift. When the pressure in the lava reservoir is greater than the pressure on the rock roof above it, it bursts outward into a volcano.

During an eruption, a red-hot gas, liquid, or solid substance suddenly emerges. These substances accumulate around the opening, forming a cone-shaped Can Son mountain. A "crater" is a depression at the top of a volcanic cone, with openings leading to the surface.

The cone-shaped mountain is a product of volcanic formation. The material emitted by the volcano is mainly gas, but large amounts of volcanic rock and solid material such as slag and ash are also ejected.

In fact, volcanic rock is magma erupted by volcanoes, and when the magma rises to a height close to the earth's surface, its temperature and pressure begin to drop, and physical and chemical changes occur, and the magma becomes volcanic rock.
