The mainstream view of why the moon has craters?

The reason why the craters on the moon are so conspicuous is that there is no atmosphere on the moon, so when the little stars hit the moon, they hit the surface of the moon at a very fast speed. There is no deceleration friction in the Earth's atmosphere at all. After the meteorite hits it, the contact part melts at high temperature and even vaporizes.

A lot of energy is released in an instant. But the enormous inertia will cause most of the meteorites to burrow beneath the lunar soil. A large amount of lunar soil splashed in all directions.

Splashing lunar soil and falling backfill, a crater was formed. At this time, the meteorite, except for the part that melted and splashed out at the high temperature, was in the depths of the crater.

There are many, many large craters on the Moon. There are tens of thousands of those with a diameter of more than 10 kilometers. There are also quite a few more than 100 and 1000 km.

The energy of these meteorite impacts is enormous. If it hits the earth, it will destroy the ecological environment on the earth on a large scale. It has even caused species extinction.

If there were no moon, these meteorites would have crashed directly into the Earth. The fact that there are so many craters on the Moon is actually a testament to the fact that the Moon has made a huge contribution to the preservation of life species on Earth. The craters are all medals of merit for her outstanding contributions to the protection of life on earth.

Most people believe that the moon resisted some of the meteorites that flew to Earth.

Factors that affect the size of lunar craters include:

2.The size of the impacting object: Large meteorites form larger craters when they hit the surface of the moon at high speed.

3.Impact angle: An impactor that hits the Moon at a shallower angle creates an elliptical or elliptical crater, while a vertical impact creates a circular crater.

4.Composition of impacting objects and the surface of the Moon: Objects made of denser substances, such as iron, form deeper craters than objects made of lighter substances, such as ice or rock.

The density and composition of the lunar surface itself also varies, with some places being more porous than others.

The above are some of the factors that affect the size of the lunar crater, and these factors interact and together affect the size of the lunar crater.

The factors for the size of the crater on the moon are as follows:

1. Large meteorites form larger craters when they hit the surface of the moon at high speed.

2. The hardness, density and rate of rocks and soils on the surface of the moon that can form craters will affect the liquid-material pulsation force of meteorites and the range of shadow worms.

For the moon, this big planet, we also had countless people in ancient times, and they had a lot of feelings for it, some missed their hometown for the moon, some thought of the story of Chang'e running to the moon for the moon, and some wanted to go to outer space to see what this star really looked like. However, at that time, it was just a matter of thinking about it, because the vertical chain was not a backward high-tech level at that time, and it supported the pace of everyone's exploration of science.

However, now the times have changed, here nearly a hundred years of time, people's high-tech has gained a rapid development trend, and because of this, the previous very long aerospace dream with everyone, for us all, has already been completed, and because of this, we now have high-tech support points, we want to explore the moon that has been appearing since ancient times. However, when we went to explore the moon, we realized that this moon was not the object that everyone called "white jade plate" in their childhood.

On the other hand, its real appearance is very different from what everyone imagined. Above the stars, there are bumpy holes everywhere. Therefore, in the case of our view, everyone was taken aback.

But soon, everyone began to think that it was very likely that this moon did not have so many potholes when it was born, so why did there have so many craters on the surface of the moon today?

For this matter, our biologists have carried out some scientific research, and found that there are many meteorites around the moon, and this kind of meteorite, experts guess that it has a very big relationship with the craters on the moon. Some people even think that the moon is often so pitted, and it is likely that the moon has helped everyone resist the collision of meteorites. But biologists have come up with a denial of this view.

Since the collision of meteorites can be said to be arbitrary, there will be no such situation as the moon blocking disasters for the earth, and on the other hand, the composition of the moon is composed of rock formations, so if the meteorite hits the moon, we can expect that it will be a dry scene, naturally because of the net weight of the meteorite, and its relative height, according to Newton's law world, we can see how big this impact is. That's why there are so many craters on the moon.

Conversely, why is it not easy for the earth to be like this? In other words, if a meteorite hits everyone's earth, there is a very high chance that it will sink into everyone's sea and will not harm people's land. Moreover, our earth has an earth's atmosphere, which can buffer the impact force of meteorites, and when the rest of the grandchildren land, it will reduce a certain amount of lethality.

We are not prone to great damage to the earth.

The mainstream theory is that it was formed by the impact of some small meteorites in space, and through these craters, scientists have explored the phenomenon of moon flashes.

It was formed by the collision of some meteorites in space on the surface of the moon. You can explore the mass of the meteorite, the ascending index can also be used to explore the movement process of the meteorite, you can also explore the material of the meteorite, and you can also determine which planet the meteorite is launched from.

It is because the surface of the moon has been hit by other meteorites, so the meteorite lifting crater has been formed, and scientists can study the size, width, depth, and mass of the meteorite according to these craters.

Formed by the impact of debris in the universe. Many elements can be detected, and there may be some high-energy radiation.

This is because there are many meteorites that happen to reach the surface of the moon, and this situation will occur, and according to the crater, the geological origin of the moon can be better explored, and the moon can be better explored.

The following information is provided about the experimental principle of the lunar crater with different ball heights.

1) To ** the relationship between the crater and the cross-sectional area, should.

The mass of the control ball and the height of the fall are the same, and the cross-sectional area is different, so the small ball with the missing smile number is the male S;

2) To ** the relationship between the large crater and the drop height, it needs to be small.

The mass and cross-sectional area of the ball are the same, and the falling height is different, so the same ball can be dropped from different heights, and the size of the bunker can be observed;

According to the influence of potential energy, when falling from a higher place, the bunker is more cautious.

deep, the mass and cross-sectional area of the available meteorite are the same, and the height from the moon.

The larger the degree, the larger the crater

So the answer is, (2) make the same ball fall from different heights, and observe the size of the bunker; The mass and cross-sectional area of the meteorite are the same, and the greater the height from the Moon, the larger the crater

The largest crater on the Moon is the South Pole of the Moon-Aitoken Basin, which is about a kilometer in diameter and kilometers deep.

It is reported that this is an asteroid that collided with it in the southern hemisphere of the moon, forming this huge crater.

Beautiful Moon.

A crater on the surface of the Moon.

The distribution is extremely uneven. The far side of the Moon.

The craters are densely packed one after the other, and most of the mountains on the moon are also distributed on the backside. There are surprisingly few craters on this side of the Earth, and there are not many craters.
