Why is the front of the moon so much flatter than the back side?

As for why there are more craters on the back than on the front. I think there is a relationship between the two sides. First of all, it may be that in ancient times, the front side of the moon suffered a strong impact that penetrated the lunar crust, causing a large amount of basalt to flow out, forming a lunar sea.

The impact had an impact on the mass distribution of the Moon, so that the impact surface would eventually face the Earth forever. Secondly. Because it is facing away from the direction of the earth, it is the shield of the earth, and the asteroids that crash into the earth naturally hit the back side more.

Heat generation occurs in the frontal hemisphere, and there is some evidence that the two sides of the moon do produce heat differently. Other factors, such as surface uplift and crustal thickness, also affect basalt eruptions. However, there may be another reason, that is, meteorites that hit the earth were "intercepted" by the moon, and most of them hit the side of the moon facing away from the earth.

The Moon is the "guardian" of the Earth. When some meteoroids and asteroids in the solar system are hit by the Earth's gravitational pull, they first have to pass through the barrier of the moon. And for an alien object to reach the Earth, it must first face the side of the Moon facing away from us.

Although the Moon is less massive than the Earth, it is still a behemoth for asteroids or meteoroids, and these objects will crash into the Moon under the gravitational pull of the Moon. And the chances of crashing into the moon facing away from us are obviously much greater than the chance of crashing into the side facing us. This is also one of the reasons for the apparent difference in morphological characteristics between the two sides of the Moon.

It may be that in ancient times, the front side of the moon suffered a strong impact that penetrated the lunar crust, causing a large amount of basalt to flow out and form a lunar sea.

Because there is sunlight on the front, there can be some changes.

Because the front has been shining with the sun.

Because the two sides of the matter are different, specific scientists are still researching.

Because the far side of the moon will not be eroded.

Because one side can be illuminated by the sun.

I can't say this clearly, but it may be because of the sun's irradiation.

We haven't seen the far side of the moon either.

Moon. The main difference between the front and back is the difference in the area of the lunar sea and the amount of impact. The characteristics of the two hemispheres are markedly different, with many huge lunar seas on the front (this is a cognitive error of early astronomers who thought that these plains had water, so they called them seas); The other side was hit and there were dense craters, only a small amount, and about the area was covered by the sea, compared to the sea on the front.

The most likely explanation for this discrepancy is that heat generation is concentrated in the frontal hemisphere, as has been confirmed by rays from lunar prospectors.

eruptions, but none of this explains why the South Pole-Aitoken Basin (with the lowest altitude and thin crust on the Moon) does not have as much volcanic activity as the storm ocean in front of it.

It is reflected in the material composition, morphology and structure, rock age, etc.

The moon should be a planet that earthlings are more familiar with, there are myths and stories about it in ancient times, and there are feats of human landing on the moon in modern times. And in the small number of ** you can see about the moon, the surface of the moon is always pitted, in fact, there is a reason why it has such a landform.

One is that the moon does notAtmosphereso it is easy to be attacked by meteorites. In fact, in the long galaxy, there are often meteorite impacts. Meteorites occasionally land on Earth, but most of them have already burned up in the atmosphere, so the damage caused by meteorites to the Earth is limited.

However, the moon has no protection from the atmosphere, and when a meteorite hits it, it hits it straight through, causing various injuries to the surface of the moon, and over time causing the phenomenon of craters on the surface of the moon.

The second is that the moon does notEcosystem, so its ability to heal itself is weak. You must know that the earth's atmosphere also brings an ecosphere, with rivers and lakes, windy sand and rocks, which can help the earth recover craters. There is no such biosphere on the moon, and the damage caused by meteorites is almost permanent, and there is no way to restore its surface to its original state through the self-repair of its own ecosphere.

Some of the moon's "pristine" nature has remained for 4 billion years, as some craters are 4 billion years old.

The third is that the upper level of the moon has been violentVolcanic eruptions, the post-volcanic topography has not changed. It is well known that volcanic eruptions not only destroy the surface of the moon, but also form cratered surfaces when some erupted liquids solidify. And such a landform has not been changed by the self-repair of the moon, which has caused permanent damage to the earth's surface, which naturally makes its surface appearance "worse".

Fourth, there is a phenomenon of weathering in the soil on the surface of the moon, and such weathering is irregular. According to the Daily Mail

Coverage of the far side of the moon.

The area collects a lot of solar storms.

emitted high-energy particles, lunar soil.

also known as floating soil), when these charges accumulate to a certain extent, they will cause a micro-flash, and the charge will suddenly penetrate the soil. There will be small-scale eruptions on the surface of the moon under radiation, and this phenomenon is also one of the important reasons for the cratering of the lunar surface.

In short, such a phenomenon will form on the surface of the moon, and it will not be caused overnight, and the cause of this phenomenon is not single. At present, the exploration of the moon by earthlings is still ongoing, and I believe that there will be more and more scientific evidence to guide us to correctly understand the real moon, and its landforms are also waiting for everyone to explore.

Because there is no air on the moon, objects outside the moon quickly fall to the surface of the moon, so the surface of the moon is potholed and sold high.

If you look at the surface of the moon with an astronomical telescope, you will find that on the surface of the moon, in addition to many mountains and large plains, there are many circles of different sizes, and what are these circles?

These circles are craters on the Moon. In the hemisphere that we can observe, there are as many as 300,000 craters with a diameter of more than 1 kilometer, and the craters that Lu Nian encounters can reach 300 kilometers in diameter.

How are these craters formed?

Some scientists believe that there was once a violent volcanic eruption on the moon, and after the material ejected from it solidified, the current crater was formed. Because the moon has very little gravity on the surface and volcanic eruptions are large, huge craters are formed.

Some scientists believe that because there is no air on the moon, meteorites can directly hit the surface of the moon, and the material that bursts out of the collision is piled up to become the current craters. Through their observations, they also found that these craters are generally accompanied by "radial lines" that stretch in all directions for several kilometers. They speculate that this is due to the fact that the material that erupts after the meteorite impact has no air resistance, and some of it splashes very far and spills on the surface of the moon.

Because the moon used to spin very fast, and if it turned fast, it was easy to hit nearby asteroids, so there were many craters.

The far side of the Moon is the side of the Moon that always has its back to the Earth. The first image of the far side of the moon was taken by the Soviet Union's Luna-3 spacecraft in 1959, and humans did not see the far side of the moon directly with their eyes until the Apollo 8 mission orbited the moon in 1968. The terrain on the far side of the moon is dominated by a large number of undulating impact craters, and humans who have landed on the moon have known that the surface of the moon is a desolate desert with only endless space dust.

Later, astronomers discovered that the Sun is exactly 395 times as far from the Earth as the Moon is from the Earth, and the diameter of the Sun is exactly 395 times that of the Moon, so the Moon as seen on the ground is exactly as big as the Sun. The diameter of the Earth is 12,756 kilometers, the diameter of the Moon is 3,467 kilometers, and the diameter of the Moon is 27% of the diameter of the Earth. Scientists call the stars that revolve around the planets "satellites," and the larger planets in the solar system each have their own moons.

A moon as large as the Moon is a very special thing in the solar system.

The moon has been following the earth for 4.6 billion years, and it may have been watching the earth every day before there were humans on the earth. In the past, everyone said that there was a Guanghan Palace on the moon, where an ancient beauty lived - Chang'e, a white rabbit, and a Wu Gang who was cutting down laurel trees every day. However, on July 19, 1969, the American "Apollo God 11" spacecraft landed on the moon, and did not see the Guanghan Palace, did not find Chang'e and White Rabbit, and did not find Guishu and Wu Gang, but there were more speculations about extraterrestrial creatures

Are there any intelligent beings known who have been to the moon before humans? It remains a mystery until now.

The far side of the moon is sometimes referred to as the "dark side of the moon," meaning that it is not visible from the earth and is not illuminated by the sun's rays. It's not the same as the front. There are not many lunar seas on the back, as on the front, but very many craters, probably to defend the Earth.

The far side of the moon has some rugged mountains such as craters and the lunar sea, which is the same as the front side, the moon is a circular sphere, and the front and back sides we see are the day and night sides of the moon.

The back side of the moon is the same as the front side, because the moon is also an Earth-like Earth, and its back side is just like the front side of the earth, and it has a potholed, earthy yellow surface.

The back side of the moon is about the same as the front side, and it is still the moon, except that the back side is more pitted and not as flat as the front side.

Why is there such a big difference between the front side of the Moon and the far side of the Moon? After reading it, refresh the cognition of the moon!

Why is there no "face" on the far side of the Moon?

In 1959, the Soviet spacecraft Luna-3 showed the world images of the far side of the moon for the first time. At that time, astronomers wondered about the high ground on the far side of the moon. No one can explain why the far side of the Moon is so different from the side facing the Earth.

The far side of the moon is covered with craters. Compared to the Earth-facing side, there are no dark spots on the far side of the moon (these dark spots are formed by large areas of basalt). It is precisely because of these dark spots that the "human face" on the surface of the moon is created.

Astrophysicists at Penn State believe they've solved the puzzle. The absence of dark spots on the far side of the Moon proves the presence of a thick layer of deposits of aluminum and calcium on the far side of the Moon.

One theory suggests that in the early days of the Earth's formation, a planet the size of Mars hit the Earth. This time the impactor was ejected into space and eventually formed the Moon. The tidal action between the Earth and the Moon is such that it is always the same side of the Moon facing the blazing Earth.

As a result, the Earth-facing side of the Moon always remains hot, while the far side cools down. This creates a thick crust on the far side of the Moon.

These astrophysicists at Penn State also believe that it is this hard crust that prevents the basalt magma from flowing out of the surface. When meteors hit the Moon, they are able to break through the surface of the side facing the Earth, causing magma to flow out, which forms the dark spots that make up the "face".

But researchers at the Massachusetts Institute of Technology have drawn new conclusions from new information provided by NASA's "Holy Grail" program. They believe that the "face" on the moon may have been caused by magma inside the moon, rather than by an asteroid impact. However, these researchers are not sure how these magmas are produced.

Because the far side of the moon does not shine any sunlight, and there is no light, it will cause a large difference between the back and the front.

This is due to the rotation of the Moon, which is very slow, which is why this happens.

Because the front side of the moon is always facing the Earth and the back side is always facing the universe, there is a big difference.
