Common craters, but no meteorites have ever been seen in the crater, where have the meteorites gone?

Craters are mainly formed on the surface of moons or small stars and other celestial bodies after meteorite impacts. Usually they appear to be a ring-shaped, concave-shaped pit. Some craters are particularly large, which are also known as craters.

We often see a lot of meteorite falls on the Internet, and we also see a lot of craters. But a lot of people are curious.

Why are there only craters and no meteorites? Was the meteorite too heavy and stuck in the dirt, or did it bounce after the fall and caused the position to shift? In fact, after the impact of a meteorite, because the composition of the meteorite has certain particularities, its minerals will be rapidly refined.

The metal substances contained in it also undergo a melting reaction due to the high temperature caused by the impact. The meteorite hits, and its speed is very fast. And the speed of the fall after the impact is also very impressive.

In the process of falling meteorites, the meteorite will rub against the atmosphere, which will also bring high temperatures. Meteorites landed, in addition to the impact of their own impact and the earth's atmospheric environment. In the process of falling, the volume is constantly changing.

The meteorite was originally large, but in the process of landing, due to the compression of air, it caused consumption. So a very big meteorite, it becomes very small. We saw a beautiful meteor in the sky.

In fact, those meteors with long tails are flames created by friction in the atmosphere. Its momentum can push the surface of the earth out of a deep pit。Although the meteorite itself is comparatively smaller.

And the meteorite after smashing out of the pit will be affected by the ** force. and shattered and spread to other places. So that's why we see a huge crater, but we can't find a meteorite of the same volume.

Meteorites burn up by the time they hit the ground, and even small ones scatter elsewhere.

The meteorite has become smaller, and it is not that the crater is as big as the meteorite.

When a meteorite falls from a high altitude, it's going to be very hot, it's going to melt it, and it's probably already melting when it hits the ground.

After smashing out of the crater, the meteorite will be affected by the ** force.

Meteorites are craters because of the ring-shaped craters formed by meteorite impacts on the surface of planets, moons, asteroids, or other celestial bodies. A central cone may form in the center of a crater with a diameter of more than 4 km. The crater may be filled with water due to rainfall and other reasons, forming an impact lake.

On celestial bodies with weathering processes or on celestial bodies with crustal movements, old craters are gradually worn away. For example, on the earth, through weathering, the accumulation of wind-blown dust and sand, and magma impact craters will be covered up or worn away. The formation of known craters on Earth ranges from about 1,000 years ago to 2 billion years ago.

However, craters dating back 200 million years are rarely found, as geological processes have wiped out most of the old craters.

The meteorite is affected by gravity and rushes towards the earth at a very fast speed and collides with the ground, resulting in high temperature and high air pressure, which directly makes the meteorite also vaporized. The meteorites in the crater did not disappear for no reason, because they were turned into fragments or vaporized directly after hitting the earth, so it is difficult to detect the existence of meteorites.

Why can't I see meteorites in the crater?

According to scientists, meteors hit the Earth almost every day. Most of the meteorites are dropped from the asteroid belt, in space, there are many asteroids are in normal orbits, but because of the collision between them, they often produce a huge impact force, causing the asteroid to deviate from its original orbit, its speed exceeds 11 kilometers per base second, when it enters the atmosphere, it will produce a lot of heat, resulting in the planet **, forming a meteor shower. The rest of the meteor will fall to the surface, creating craters, and when the meteor hits the surface, it will be like a nuclear bomb**, and the surrounding air and meteorite will be vaporized.

But it is also not excluded that when meteorites **, some fragments will be left, and these fragments will be taken by scientists for study.

Are all these meteorites gone?

In fact, not only there are no meteorites on the earth, but there are also no meteorites in the craters on the moon, because the shock wave generated by the meteorite ** will bring the remains of the meteorite to space, and may even cause collisions with other asteroids. In other words, the meteorites in the crater do not disappear out of thin air, and once they hit the surface, they immediately turn into meteorite fragments or evaporate, which is why meteorites are so difficult to find in the crater.

It can be seen from this that the disappearance of meteorites is mainly due to the fact that the meteorite is directly vaporized in the air, and of course there will be some fragments that can be found, and meteorites hit the earth almost every day. That's all I have to say about meteorites, I hope it can help you.

Meteorites are fragments that fall on Earth after the disintegration of some asteroids. Many craters do not contain meteorites, which have been weathered naturally.

It is possible that someone else has moved them, because these meteorites have a lot of use, for example, they can be used for research.

Because after the fragments of these meteorites entered the earth's atmosphere, they were in a burning state when they landed, and when they landed, they had already turned into ashes, so they naturally could not be found and smashed by humans.

The reason why there are no meteorites in the crater in the first point is that in the process of impact, the meteorite has been crossed out, and the second point is that after hitting the earth, the meteorite in the meteorite is basically wiped out, turning into a kind of sand flow, and slowly disappearing.

Because most of the minerals will be vaporized after the meteorite hits the earth, and a small part of the metal is in a molten state, there are no meteorites. The meteorite either vaporized or melted.

After the meteorite hits the earth, the power is very large, and after the impact, the meteorite will form a grain of meteorite slag, and finally it will merge with the surrounding environment, and some will become gaseous meteorites.

Once upon a time, dinosaurs lived carefree on this earth, and at that time, they were the overlords of the earth. However, just one day 65 million years ago, a huge meteorite fell from the sky. Suddenly, the sea poured in, the earth trembled violently, and the whole earth fell into a great catastrophe.

In this catastrophe, about 80% of the world's species were wiped out, including dinosaurs.

As the long river of history rolls forward, the meteorite that once brought great disasters to the earth has long since disappeared, leaving only a huge crater. On the Yucatan Peninsula in Mexican territory, there is a crater with a diameter of about 180 kilometers called Chicxulub Crater. According to scientists, the Chicxulub crater was left behind when the meteorite that destroyed the age of the dinosaurs hit the Earth.

So why did it leave only craters? The meteorite itself went to ** again?

Meteorites are huge stones that have fallen from space. So why did they fall out of space? Actually, this is the same principle as the apple falling from a tree, because of the gravitational pull of the earth.

As a simple example, a stone in space that is moving along its own orbit will be gravitationally attracted and deviate from its orbit when it approaches a larger celestial body.

In this way, it is easy to collide with stones on other tracks. Of course, there is also the possibility that the stone was knocked down from another celestial body, and it crashed directly into another celestial body. Either way, once you hit it, here are a few things that happen.

The first is that the meteorite hit the celestial body with a relatively small mass and a weak gravitational pull. Then after impact, the meteorite will bounce up and hit a crater, and then bounce up again. If the meteorite bounces faster than the escape speed of this small celestial body, then it will enter space again.

The second is that this meteorite has a higher density, such as the iron meteorite, which hit the soft ground with a low density when it hit the celestial body. Then due to the effect of gravitational acceleration, the speed of this meteorite will be very fast, and it may drill directly into the soil when it falls. If you don't dig it out, I'm afraid no one will know where it is hidden.

The third is the fact that the meteorite collides with the ground that hits the ground, such as the meteorite that destroyed the dinosaurs as we mentioned at the beginning. After it collided with a celestial body, it had a tremendous impact. This impact force either crushes the meteorite itself and sputters it far away, or it converts a huge amount of mechanical energy into heat energy, instantly forming a fairly high temperature, melting or even vaporizing the meteorite.

That's why it's so hard to see meteorites in craters. And those huge craters are as if meteorites are writing their own way to travel here.

Where did all the meteorites in the crater go? After reading it, I will solve my doubts.

Most of the parent meteorites that fall to the ground to form craters disintegrate during impact. There are many huge craters in the world, such as Barringer Crater in Arizona, USA, with a diameter of 1,240 meters; Xiuyan Crater, located in Anshan City, Liaoning Province, China, has a diameter of 1,800 meters.

Attentive friends may notice that at these craters, there are no large meteorites, only special elements extracted from the soil by scientists; There are several reasons why there are no meteorites:

1. Melt and disintegrate: When the parent meteorite enters the earth's atmosphere, the high relative velocity causes the meteorite to rub against the air, resulting in a high temperature of tens of thousands of degrees, which is enough to vaporize any substance.

Therefore, only the parent meteorite with a larger mass can fall to the ground to form a crater; When the meteorite collides with the ground, it will also generate extremely high pressure and temperature, and the huge energy release will melt the meteorite and completely disintegrate, leaving a crater behind.

At this time, the parent meteorite no longer exists, and the whole meteorite material is either vaporized, or the melt is fused with the material around the crater, or it is thrown around by a huge impact.

2. Picked up: Millions of tons of meteorites fall into the Earth's atmosphere every year, most of which fall into the oceans and poles; The parent body of the meteorite with a small mass cannot reach the ground at all, and only a very small number of meteorites have solid residue after passing through the atmosphere.

Therefore, the meteorite itself has a certain scientific research value, such as the famous "Alan Hills 84001 meteorite", which was discovered by scientists in the South Pole and fell to the earth more than 100 million years ago. It is precisely because of the particularity of meteorites that the market for meteorites is also very high, and the fragments of meteorites scattered near the crater are basically picked up.

We can often see all kinds of meteorite-related news on TV or the Internet, and the meteor we love is a meteorite. As early as 65 million years ago, the dinosaurs that dominated the world were extinct due to the impact of meteorites, and there are still huge craters in Central America. Speaking of which, I don't know if you think ** is wrong, that's right, where did the meteorite go?

In fact, the meteorite has been shattered, leaving only the crater.

There is a special existence in meteorites, and that is comets. Comets are not like the big boulder meteorites that we remember, the main components of comets are ice (water) and dust. So when the comet hits the Earth, the ice melts, and the dust mixes with the dirt, and the comet disappears without noticing.

In general, the meteorite is not gone, but exists in a different form, leaving only a crater that is difficult to fill.

Whether or not the crater will have a meteorite will remain, depending mainly on how fast the meteorite lands on Earth

According to scientists, it is generally believed that if the meteorite falls at a speed of less than 12 kilometers per second, then there is a possibility of the existence of a meteorite. If the meteorite is falling at a speed greater than 12 kilometers per second, then it is unlikely that there will be a meteorite in the crater.

Because during the meteorite landing, the meteorite hit the earth and collided violently with it. During the collision, the meteorite broke up into very fine particles. In other words, in the process of colliding with the earth, he smashed himself to pieces.

Because we all know that the faster the speed, the greater the impact. That's why it's best to control a reasonable speed when driving to avoid accidents as much as possible. If there is a car accident, the speed will determine the severity of the accident.

In fact, 100 years ago, when the world discovered a crater, scientists at that time did not think it was a crater. They all thought it was a trace produced by the air, but later after scientific research and demonstration, they knew that it was a trace of a visitor from outside the sky.

At the same time, after demonstration and speculation, after instrumental measurements, fine meteorite particles were found around the crater. At the same time, with the rapid development of all aspects of global astronomy, in the process of observation, we can also try to go to the meteorite landing as much as possible.

In the process, we discovered that the composition of meteorites is mainly stony and iron. This gives us a very large basis for studying the landing of meteorites, as well as the craters. Although we still don't know if there is a living space for extraterrestrials.

But with the development of society, we will further explore and decipher the universe, and I believe that there will be results.
