The main reason for the absence of living things on the Moon and its susceptibility to being hit by

The mass and volume of the Moon are small, so there is not enough gravitational attraction to attract the atmosphere to wrap around the surface of the Moon, and the planet can directly hit the surface of the Moon. The earth is different, there is an atmosphere that can be used by living beings to breathe, and most of the meteors are burned up in the process of entering the earth's atmosphere, and only a very small part reaches the ground, becoming meteorites or meteorites.

Because the moon's gravity is small, and there is no oxygen and no atmosphere, it is all hydrogen and nitrogen, the diameter of the moon is about 3476 kilometers, which is 3 11 of the earth, the volume of the moon is only 1 49 of the earth, and the mass is about 735 billion tons, which is equivalent to 1 81 of the earth's mass, and the gravity of the moon surface is almost 1 6 of the earth's gravity.

--- there is no atmosphere (the mass is too small)!

The Moon and Earth are held together by gravity, which provides stability to the two celestial bodies. Without the Moon holding the Earth in place, the Earth's planetary axis would have moved more violently, perhaps even overturned, as was the fate of Mars, causing the Earth's poles to move violently. This makes life even more difficult, given that the Arctic of the world occasionally shifts to the equator and vice versa.

It will be more difficult to settle permanently in some areas.

<> Moon directs certain life cycles on Earth, although the Moon's influence on menstruation and birth rates is largely underestimated. However, for those nocturnal animals with circadian rhythms based on the lunar cycle, their evolution and survival would certainly suffer if the moon suddenly disappeared. Throughout history, lions, bats, insects, and countless other animals have evolved behaviors such as mating, hunting, and hibernation based on the appearance of the moon.

It is conceivable that evolutionary history would have taken very different paths and might not even lead to the emergence of humans. We can see countless craters of various sizes on the Moon, most of which help keep the Earth at bay. If some very large meteorites land on Earth, it will be a devastating and terrible disaster.

From the above analysis, we can see how important the Moon is to the Earth. Scientists propose to destroy the moon, and many people support it. Now that we know what the Moon means to the Earth, you can see how stupid it is to propose to destroy the Moon, not to save the Earth, but to destroy it.

If there really is an alien civilization invading the earth in the future, we must not only protect the earth, but also the moon. If the Moon is destroyed by an alien civilization, we will lose an interstellar war, even if humanity finally exterminates the invading aliens. Because an Earth without the Moon will continue to experience major ecological changes, we may eventually have to abandon Earth and move to another planet.

The above is a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, thank you.

Summary. If there is no moon, although our earth is still the earth, and many of them have no magnetic field, etc., life on the earth is likely to be non-existent, because without the moon, the earth is likely to become a lifeless planet like Venus.

What would happen to the Earth without the Moon?

If there is no moon, although our earth is still the earth, and many of them do not have magnetic rackets, etc., life on the earth is likely to be non-existent, because if there is no moon, the earth is likely to become a planet without life ascension like the Venus bench.

The volume of the moon is 1 49 of the earth, and the mass is 1 81 of the earth, which is the highest mass of the moon and the planet among the eight major planets in the solar system, so the moon is large enough to produce a large enough gravitational force on the earth, so that the lava inside the earth has been active, and the earth's rotation speed is fast enough, so that the earth's magnetic field can also be maintained, and the existence of the earth's magnetic field can protect the existence of the earth's atmosphere, so that the atmosphere is not blown by the solar wind, In turn, the water resources and ecological environment of the earth are protected, so that there can be living species on the earth.

If there were no moon, then there would be no tides on Earth. The gravitational pull exerts on the Earth's virtual sphere, and this traction pulls the Earth's oceans, causing the Earth's tidal phenomena, including: ocean tides, solid tides, and atmospheric tides.

The first is that there is a certain impact, after all, the hilly terrain on the far side of the moon is actually a remnant of the second moon. The Moon once orbited the Earth and then embedded itself in what is now the surface of the Moon. It is not difficult to explain why the far side and the front of the moon are completely different:

They were originally sold with two planets. Because the Moon's rotation and revolution are perfectly synchronized, one hemisphere of the Moon is always facing the Earth, while the other hemisphere is always facing away from the Earth and never shows her face. Large areas of grayish-white hills stretch across the surface of the moon, rugged and vast.

This is very different from the flat terrain facing the earth.

Secondly, because the impact point was on the far side of the moon, and no lunar satellite flew past the impact point at that time, people could not get the exact location and situation of the impact in the first place. A team of researchers at Arizona State University analyzed high-resolution images taken by the LROC as it passed through the Herzplain crater before and after the impact, and not only confirmed the impact, but also accidentally discovered that the impact of the UFO had formed two connected craters, with the 18-meter-diameter crater in the east partially overlapping the 16-meter-diameter crater in the west.

Moreover, it is completely normal for the moon to be impacted, but this event is quite special. China released the world's first 1:2.5 million geological map of the full moon of the moon, and this geological map was obtained from the data obtained by China's Chang'e project, and then the data was summarized and analyzed on the surface of the moon.

The results of geological change exploration were counted. And this image of the moon makes full use of other international lunar exploration data and research results.

You know, in ancient times, the Earth had two moons, one of which was very small, and the other was the moon as we see it. The smaller moon collided catastrophically with the larger one, a theory scientists believe could be used to explain why the probe found such a big difference between the other side of the moon and the side facing the Earth. According to computer simulations, the ancient moon collided with a "small moon" (less massive), and the sedimentary effect could be used to explain the high ground on the far side of the moon.

There is a certain impact. This will disrupt the original exploration plan and greatly increase the time cost.

Needless to say, there will be an impact. After all, the hilly terrain on the far side of the moon is actually a remnant of the second moon. The Moon once orbited the Earth, and then embedded in the current unbalanced Moon withered on the surface, as for the specific impact?

Scientists still need to study it.

Of course, it has an impact on hand blindness, at least through the traces left by this collision, you can use the potato code to detect which planet it collided with before, and what kind of impact did it become? Will there be an impact on the moon?

Yes

The Moon's geological activity has ceased about 100 million years after its formation (4.5 billion years from this month) and the inner core has cooled. Since then, there have been no more volcanic eruptions, plate movements, and magnetic fields.

The inner diameter of the earth is still molten due to the decay of heavy elements, and volcanoes and plate movements are still active. In the history of paleontology, volcanic and geological activities have had a significant impact on the evolution of life (such as the Ordovician mass extinction, the Permian mass extinction, the humid Devonian, the dry Cretaceous, etc.). Even in our daily lives today, volcanoes, **, and hot springs are commonplace.

On the other hand, the Earth currently has the only powerful and symmetrical magnetic field among terrestrial planets, which prevents the solar wind high-energy particles from directly rushing into the atmosphere and stripping the latter away (see Mars for comparison), providing the first shelter for the existence of life.

Comparing the two, I believe the subject can agree with my initial conclusion.
