The moon is the wife of the earth, the sister, the daughter

The theory of the origin of the moon is very profound, but this article is written vividly and vividly, and one of the important reasons is that the cloud has successfully used the method of illustration such as column numbers and analogies, please find the corresponding example sentences:

More than 4 billion years ago, when the solar system was formed, the Earth and the Moon were originally one.

However, this theory faces many difficulties, such as the inevitable corollary that the position of the Moon should be on the equatorial plane of the Earth, which is not the case.

I guess this should be it, right??

Earth-Moon Relationship: Moon.

With its gentle gravitational pull (about Newton.

Gently tugging at the earth, it directly contributed to the development of life from the sea to the land. The area of the Earth directly facing or facing away from the Moon is pulled up by this force. If this is the ocean, tides will form.

There are two ebb and flow times for every rotation of the Earth. The moon tide brings organic-rich waters to the edge of the land. At the junction of land and sea, some aerobic organisms survived tenaciously and became the earliest land organisms.

The Earth and the Moon orbit each other, and the two celestial bodies rotate around a common center of gravity 1,600 kilometers below the surface. The birth of the moon has added a lot of new things to the earth. A long, long time ago, the earth had a large temperature difference between day and night, and the temperature was between the boiling point and the freezing point of water, which was unsuitable for human habitation.

However, the special effect of the Moon, the gravitational pull on the Earth's seawater, slows down the Earth's rotation.

and the speed of revolution, so that the earth's rotation and revolution period tend to be reasonable, bring us precious four seasons, reduce the temperature difference, so as to be suitable for human habitation.

Through scientific research, we all know that the moon revolves around the earth, and the moon revolves around the earth, that is, a day and a night.

If there were no moon, there would be no earth.

Sister Moon's companions from Earth include exploration satellites, meteorological satellites, oceanographic satellites, communication satellites, reconnaissance satellites, and Shenhui Sky Kayak 7.

**In the text "Sister Moon's New Partner", "Sister Moon's New Partner" is a fairy tale text in Unit 5 of Book 3 of Primary School Chinese, Thought and Morality, Sister Moon's New Partner. It vividly introduces some scientific knowledge in an anthropomorphic way, so as to cultivate and stimulate the interest of students in loving and learning science. "Sister Moon's New Companion" tells us that the contribution of Sputnik to mankind is hungry through a dialogue between Sister Moon and Sputnik.

There are three kinds of relationship between the origin of the moon and the earth!

1.The capture said that it was a satellite captured by the Earth Zina!

2.Homologous theory is that the moon was formed at the same time as the original material that formed the earth!

3.The impact theory refers to the splash thrown by the impact of a planet about the size of Mars at the beginning of the formation of the earth, which formed the moon in orbit! (This is the most popular and most widely acknowledged term).

Earth-Moon relationship: It belongs to the planetary system, the earth is the main star, the moon is the satellite, and the moon revolves around the earth!

The role of the Moon, 1Slow down the Earth, the autobiographical speed of the Earth at the beginning of its formation is about 9 hours per revolution! Descend through the deceleration of the moon to now 24 hours a day!

2.Protecting the Earth can make it clear that the Earth's orbital garbage (referring to meteorites and meteoroids in the universe) saves the Earth from impact, because except for a few meteorites that fly towards the Earth at an angle, most of them will rotate around the Earth and then spiral down to hit the Earth, and the Moon can use its gravitational pull to attract it to the Moon at this time! 3.

Tidal phenomenon! Indispensable conditions for life on Earth!

My thoughts are similar to the first one, but not capture.

I think it was many billion years ago (when life on the earth had not yet formed), the earth was still the earth at that time, the moon was an asteroid in the solar system, the moon slowly under the action of solar gravity (this slow is not the kind of slow we understand, it is the kind of slow relative motion of celestial bodies) approached the direction of the sun, met the earth in the process of approaching, collided with the earth, the moon due to its large mass, ** back (of course, the earth was also hit), the speed of the moon decreased, was captured by the earth, and formed a satellite.

You see the Pacific Ocean and the Americas, the Pacific Ocean is much larger than the other oceans, and on the side of North and South America near the Pacific Ocean is the Cordillera mountain system that runs through the whole of the Americas. Why is this the case? My conjecture was formed many years ago due to the impact of the Moon, which struck the Earth obliquely from the western Pacific Ocean, that is, off the coast of our country, and ejected from the Americas.

The above part is just my own conjecture, and it has not entered an in-depth investigation, if there are similarities, then I am very lucky. Hehe!!!

1.The second, homology theory, is more plausible, because the first is unknown, because the diameter of the Earth is only twice that of the Moon, and there is no great difference between them, and besides, all the water planets known to date are much smaller than the Moon without exception; Therefore, it is not easy for a planet as large as the Earth to capture an asteroid the size of the moon.

2.Who are you, Lovely Moon? You can keep it secret, but one day humans will lift the veil of mystery about you and find out the truth about you. Using anthropomorphism and questioning, it depicts the strong determination of mankind to solve the mystery of the moon.

1. The first doctrine. Judging by the tone: "This is probably the case," and some astronomers argue that "the last speculation is more dramatic," and that "this theory faces many difficulties," says one of the astronomers

2. "Wouldn't it be wonderful to compare the earth and the moon to a husband and wife who meet and become a match made in heaven?" ”

3. Select D. "Who are you? "Not a rhetorical question.

There are many theories, one is that the Moon is older than the Earth, and the other is that it is smaller than the Earth. Why are you asking such a question?

The Moon is a satellite of the Earth.

1.Subjective questions can be answered according to one's own point of view, requiring a clear point of view and explaining the reasons.

2.Square peg. The title should correspond to the order of the article, and be elaborated in the order of wife, sister, and daughter.

24.No. Because this part is a theoretical argument and an introduction on a scientific basis, deleting it would destroy the rigor of the argument.

Footprints on the Moon" truly recorded the whole process of the American astronauts Armstrong, Collins, and Aldrin landing on the moon, and this article is a popular science **, discussing the moon**. This is the difference in content between the two articles.

In terms of the purpose of writing, "Footprints on the Moon" is to let readers understand this great process through narrative, and this article is to make readers understand the various speculations about the origin of the moon through discussion, bring readers questions, and explore the real answers.

1. Judging from the introduction in the article, which of the three theories about the origin of the moon do you think is more credible? Why?

This question is about your comprehension skills. It doesn't matter which one you choose, the main thing is to explain your point.

If it were me, I would prefer that they were created at the same time, that is, they were created at the same time as the Earth in the primordial nebula.

2.Not appropriate, because it's a matter of mental inertia. If you line up as sisters, wives, daughters will feel awkward and not arranged according to a certain pattern.

3.No. Because to remove it means that it is already true. So far, that's all speculation. So it can't be removed.

4.Pick D. It's easy to see with elimination.

5.Excuse me. I haven't read the article "Footprints on the Moon". Or you can send it to my mailbox. I'll read it and add an answer. It's mine.

1.(1) (3) No need, it's already in the article. (2) Put it in front of the penultimate paragraph "Look".

2."At the time of the formation of the solar system, the Earth and the Moon were formed by the condensation of the same cloud of dust. Their average density and chemical composition differ because the metal components of the primordial nebulae were condensed into clumps before the planets formed. ”

3.Reason 1 High temperature molten state, Reason 2 Rotation is very fast 5The moon is neither the wife of the earth, nor the sister of the earth, but the daughter of the earth.

6.Mankind will definitely study the origin of the moon.

Children, it's really hard for you to have time to type out such a long article + question, but why don't you want to think about it? You should do your homework yourself......

1 Cognate said.

2 suitability. Because after the change, the order of "sisters, wives, daughters" in the title is not in harmony with the order in which the three theories of the origin of the moon are explained in the article.

3 does not work, 4d

1.Sisters. Because they are all children of the solar system.

2.It's not appropriate, and if it is changed, there will be no order of the three origin theories in the article, so it should be a wife, a sister, and a daughter.

3.No way. Because "most likely" has a limiting effect, removing it is gone.

You say so much that you don't understand!

Sisters! The two of them are almost far away.

Xue Yuhan, why don't you ignore me.

1.A: Judging from the introduction in this article, I think the second of the three theories about the origin of the moon is more credible, that is, the moon may be the sister of the earth.

Because first of all, the third doctrine is too different from the facts to be excluded. And in paragraph 4, the "capture theory" is denied through the "homology theory". Therefore, the tendency should be "homology".

2.The theory of the origin of the moon is very profound, but it is written vividly in this article. Plainly clear, one of the important reasons is the successful application.

Comparisons. For example, the diameter of the earth is only twice that of the moon, and the difference is not huge.

Draw an analogy. Wouldn't it be wonderful to compare the earth and the moon to a husband and wife who meet and become a match made in heaven?

3.The following statement of the role of the last paragraph is incorrect (d).

a.Echoes the beginning.

b.Boils down to the full text.

c.The anthropomorphic method expresses the confidence and determination of human beings to uncover the traces of the origin of the moon.

d.The use of rhetorical questions expresses the strong desire of mankind to find out the identity of the moon.

4.Please use a concise sentence to directly state the meaning expressed in the last paragraph of the article.

Mankind will finally unravel the mystery of the origin of the moon.

Long waiting. May it help you!

A daughter, a wife or a sister is a relationship on the same level, and the moon is a satellite that circulates the earth and can only be a daughter.

They are sisters but not sisters, they can only be regarded as cousins.

It's all wrong! The Moon is the father of the Earth.
