Information about the changes of the moon (writing essay)

1. An essay describing the changes of the moon

We usually live in bustling and brightly lit cities. Regardless of the full moon or wane, the roads are always brightly lit, so we rarely pay attention. Observe the moon.

I remember one night I finished my homework early and went out for a walk with my parents. It was the full moon. We sat on the grass and looked up at the moon above our heads. The moonlight was not very bright and flickered. The clouds passing through seemed to have a sense of heaviness, emitting a tired light that seemed extremely weak against the brilliant lights on the ground. My mother told me that the moon at my grandma’s house was not like this. It was very bright and beautiful. This made me a little confused. Isn’t it just a moon in the sky? How could it be different?

During the Mid-Autumn Festival this year, I decided to go to my grandma’s house with my mother to celebrate the festival to find out how beautiful the moon in the countryside is. My grandma lives in a small mountain village called Lingli. The houses in the village are blocked by a mountain called Duling. When you walk into the village, you feel very secluded. If it is midsummer and friends with insomnia come here, the cicada cries can help you. Get rid of the pain of insomnia and you will surely sleep comfortably. The people in the village are hospitable and very humane, which I like.

After having a reunion dinner with my grandparents, I took some moon cakes, fruit candies and melon seeds and ran to the small attic of my grandpa’s house to enjoy the moon. I lay on my grandpa’s bamboo bed and watched the moon, high in the sky. There is a round and bright moon hanging on it. They say that the moon on the 15th day of the month is particularly bright, not bad! The bright moonlight shines on this quiet mountain village. It is very bright. You can clearly see the scattered houses in the entire village. You can distinguish even a puppy or kitten coming on the winding path. There is nothing dark in the sky. Among the clouds, there are only pieces of light white clouds drifting slowly with the moonlight. There are many naughty and blinking stars around, vying to emit their own light. No one is willing to be outdone, as if they are cheering for the festival! Look, a jumping jade rabbit appeared in the moon, accompanied by the beautiful sister Chang'e. It is said that they are bringing blessings to the world, so every time the moon is full, people like to place some offerings and burn incense sticks to express their gratitude.

The cool autumn breeze brought me some clothes, and then she sat down next to me. At this time, the moon seemed to be fuller and brighter, and my mother’s eyelashes and face were flashing. The markings on the mother's face are vaguely visible, and her mother looks a little old under the bright and soft moonlight. We both discussed these two different moons together.

As the night got deeper, I couldn't help but shiver, but the beautiful moonlight made me reluctant to leave for a long time. 2. Write a composition about the changes of the moon

Moonlight night A ray of soft moonlight shines through the window and onto the windowsill.

The window sill seems to be plated with silver. I suddenly remembered that the Mid-Autumn Festival is coming soon, and it is the time of the full moon. The moon must be beautiful at this time! So, I went downstairs to admire the moon.

What a round and plump moon! There are a few twinkling stars in the distance, adding a bit of poetry to this moonlit night. I lay on the lawn and looked up at the stars, thinking: Why does the moon become fuller and waner sometimes? As I thought about it, I fell into a trance and spread the wings of my imagination... In the magical and wonderful fairyland, there lived the Jade Emperor and his family. They controlled the earth and had boundless magic power.

But the Jade Emperor was a selfish immortal. He hated the night, so he did not assign a patron saint to the night. How terrible the dark night was. The people could not go out and could only stay at home. They burned incense and worshiped Buddha, hoping that the Jade Emperor would change his mind, but the Jade Emperor still ignored him.

The Jade Emperor had five beautiful daughters, the youngest of whom was the most beautiful. The Queen Mother gave her what she considered the most beautiful name - Yue. Yue is a kind-hearted person. She couldn't bear to see the people suffer, so she went to persuade the Jade Emperor, but the Jade Emperor not only refused to change his mind, but also warned her not to mention the matter next time, otherwise he would kill her.

Yuexin is dead, and she can no longer place her hope in her father. After repeated thinking, Yue decided to sacrifice himself to benefit the public.

Liang is Yue’s third sister. When she heard about this, she felt very sorry for her sister, so she dissuaded her sister from going against the Jade Emperor. Yue said with tears: "Sister, we are immortals, we are in charge of Dadi, we can't let those poor and innocent people suffer because of my father's selfishness! "After hearing this, Liang felt that her father was a bit too cruel, so she also supported her sister. The two came to the open space and used magic power to make a huge jade ball, but the jade ball did not shine.

The moon and the light merged into each other and turned into a fire phoenix, which flew into the jade ball. Suddenly, the jade ball shone brightly, and it slowly rose into the sky and became the moon. The Jade Emperor looked at the moon in the sky, and his beard stood up in anger. He lost his mind and cast a spell cruelly, turning the jade ball into a hard stone and breaking the stone.

As soon as the Jade Emperor finished speaking, the stone broke with a crash. The full moon in the sky turned into a crescent moon, and those fragments became beautiful stars. The Jade Emperor really didn't expect that under the care of the stars, the moon would become more beautiful, and he became angry.

The Queen Mother felt sorry for her daughter. When the Jade Emperor was ill, she secretly cast a spell to restore the moon once a month and let the stars return to the moon. Therefore, every month the moon will gradually change from crescent to full moon, and the stars in the sky will slowly return to the moon, so the stars will be scarce when the moon is full.

The kind-hearted Yue and Liang dedicated themselves, and people will be forever grateful to them. The magic of the Jade Emperor and the Queen Mother allowed people to see the beautiful changes in the full and waning moon. Perhaps people should also thank them. 3.

Write an essay based on the information about the moon

The night sky has been particularly clear these days.

Every night, you can see the bright moon hanging high in the sky, curved like a woman's thin eyebrows. As of today, the moon is still only an approximate semicircle, and there should still be some time left before the moon becomes full.

I stood by the window and looked up at the half moon outside the window. I felt relaxed and happy, and had endless reverie. A cloud as thin as a gauze floated over and slowly covered the moon, but behind the cloud, the moon's beautiful outline and misty moonlight were still charming, as if it were a The woman who is "still holding the pipa, half-hiding her face".

Yeah, the moon must have known that I was looking at her, and she felt a little shy, so she covered her face with a gauze scarf. What a fairytale night, what a fairytale moon! The clouds gradually dispersed, and the moonlight became as clear and transparent as water.

I heard a burst of innocent and hearty laughter coming from the yard. I knew that it was the four or five-year-old children from the neighbor’s house who came out to play again. Under the moonlight, they smiled so truely and sweetly that the moon seemed to laugh with them.

I have always believed that the moon is the patron saint of children - she is so pure, just like the child's spotless heart. I vaguely remembered that when I was a child, I also liked the moon so much.

Such a familiar yet unfamiliar picture emerged in my mind - a child running happily under the moonlight, pointing at the moon in the sky and shouting loudly: " Look, the moon is running with us! "That child is me. At that time, I might have asked some weird questions that these children now ask - when the moon turns into a curved hook, will Fairy Chang'e's house be enough to live in? How did the Jade Rabbit fly to the moon? And childhood is also in my laughter, slowly running away with the moon.

Whenever I think about this, "growth" becomes a scary word to me. As I grow up, I believe more and more that the moon is a desolate, barren, barren land, rather than a pink and jade palace inhabited by the beautiful Fairy Chang'e; I believe more and more that science explains it The "lunar eclipse phenomenon" is not the "tengu eating the moon" that made me both excited and scared in the past.

The childish thoughts of my childhood have gradually faded away from my thoughts. As I grow up, I gradually abandon my dreams and succumb to the coldness of reality. Therefore, my life There are no more fairy tales, no more dreams, no more fantasies about the moon. And that long-gone childhood will always be a distant past for me.

I stared deeply at these children and understood that I no longer belonged to that world, and my childhood memories had been buried in the corner of my heart. That moon no longer belongs to me either. No matter how beautiful she is, she is still so out of reach.

I lost the moon of my childhood and can never find it again. 8. An essay about the moon information

The future moon

One day, I had a dream. I dreamed about the moon in the future. I dreamed that I was on the moon. I don’t know how many years ago. One day a year later, the dream of mankind to land on the moon came true. Humanity's base on the moon has been built, and batches of people have moved into the base to start a new life. The precious resources on the moon are of amazing value to humans. Uranium, thorium, rare earths, etc. that are rare on the earth are abundant on the moon. Moreover, the volume of ilmenite in the basalt on the moon accounts for 25%, and the titanium is about 100 trillion tons. This is an astonishing amount, and humans can directly use these stones to produce water, Liquid oxygen fuel and more. The moon is really a resource-rich place! No wonder humans have always dreamed of landing on the moon. Now that dream has finally come true, I am exclaiming...

I woke up from the dream and returned to the earth. Now, it is night, and when I raise my head, I see the moon. The moon is so cold at this moment. If you go, you will become very lonely; if you go, it may be difficult to survive. Although the moon is cold, I believe that there are beautiful fairy Chang'e, osmanthus trees, and lovely jade rabbits on the moon. We can also look at the blue earth on the moon.

I believe there will be a day when physics makes everything possible. Think about it, why can people create electric lights, airplanes, trains, and ships? Would anyone in that era have thought of the possibility of an airplane? But the fact that physics has made airplanes a solid proof has made possible what the predecessors thought was impossible. This is physics. People were able to create them based on the principles of physics in the past, and in the future, people will definitely be able to live on the moon based on the principles of physics. It's not impossible. Maybe in the near future, you will be able to eat ice cream "imported" from the moon!

Don’t forget what Grandpa Yang Zhenning said, “Beauty lies in physics.” Indeed, the beauty in life comes from physics. For example, "Fish fly in the sky and birds swim in the river." This seems to be a sick sentence and it seems to go against common sense. But this sentence does describe the scenery of a place. Do you know where the scenery is? Let me tell you, it is the scenery of Jiuzhaigou. Let me explain the principle of "fish fly in the sky and birds swim in the river". The fish in this underwater painting is a virtual image formed by the refraction of light, and the bird is a virtual image formed by the reflection of light. Are you surprised after hearing this? ! Fun, right? ! Interesting, right? !

In ancient Chinese mythology, the moon is the Guanghan Palace where Chang'e lives. There are laurel trees and jade rabbits on the Guanghan Palace. The beautiful legend is about to become a reality... Let us look at the world. The moon in the future will be mankind's second home, and mankind will no longer have only one home. 9. Search for information about the moon and prepare a 600-word explanatory essay "A Day on the Moon"

The common name for the moon.

Usually refers to its bright part, so it is called. The words come from a poem by Li Yi of the Tang Dynasty, "Reward Cui Yuan, Deputy Envoy, Carrying Qin and Staying in the Envoy Courtyard to See the Instructions": "The trees in the courtyard have faded and the moon is empty, and the city anvils are anxious to face the frost.

"

Qing Dynasty Li Guangting's "Xiangyan Jie Yi·Yue": "The moon is the essence of Taiyin. However, people all over the world call it "Taiyin" instead of "Moon".

Li Yi’s poem of the Tang Dynasty... uses "complexity" as opposed to "brightness" to express its light. If you don't notice each other, you will be like the name of the moon.

Or Yue'er. Chapter 12 of "The Appearance of Officialdom": "It is better to wait until the moon rises in the middle of the night and the tide comes." "

Hu Yunyi's "Xiling Bridge: Whose Hair the God of Love Has Landed": "Looking back at this place three years ago, it seems like yesterday; the moon of that year was shining on us as we wandered eastwards. . "Edit the relevant introduction in this paragraph to basically introduce the moon. It is the only natural satellite of the earth and the closest celestial body to us. Its average distance from the earth is about 384,401 kilometers.

Its average diameter is about 3,476 kilometers. meters, slightly larger than 1/4 of the Earth's diameter. The moon's surface area is 38 million square kilometers, which is not as large as our Asia.

The moon's mass is about 735 billion tons, which is equivalent to the earth. 1/81 of the mass, the moon's surface gravity is almost equivalent to 1/6 of the earth's gravity. The moon orbits the earth in an elliptical orbit.

This orbital plane is called a great circle on the celestial sphere. "White Track". The White Track plane does not coincide with the celestial equator, nor is it parallel to the ecliptic plane, and its spatial position is constantly changing.

The minimum temperature on the surface is -183 degrees Celsius.

The moon's rotation The moon rotates while orbiting the earth, with a period of 27.32166 days, which is exactly one sidereal month, so we cannot see the back side of the moon. This phenomenon is called "synchronous rotation" and is almost a universal law in the satellite world. .

It is generally believed to be the result of the long-term tidal effect of the planet on the satellite. It allows us to see 59% of the moon.

Mainly. The following reasons: 1. In different parts of the elliptical orbit, the rotation speed and revolution angular speed do not match. 2. The intersection angle between the equatorial equator and the equator.

The physical conditions of the moon---the main topography of the lunar surface include: craters. This name was given by Galileo. It is a prominent feature of the lunar surface, covering almost the entire lunar surface.

The largest crater is Bailey crater near the South Pole, with a diameter of 295 kilometers, which is larger than Hainan Island. A little bigger. There are about 33,000 small craters with a diameter of not less than 1,000 meters.

A Japanese scholar proposed a crater classification in 1969, which was divided into Clavian type (old craters, which are generally unrecognizable, and some still have mountains within them) and Copernican type (young craters, often with "radiation"). "pattern", the inner wall generally has concentric circular mounds, and there is usually a central peak in the center) Archimedean shape (the ring wall is low, possibly evolved from the Copernican type) bowl-shaped and dimple-shaped (small crater, with (less than one meter in diameter). The dark part of the lunar surface seen by the naked eye is actually a vast plain on the lunar surface. Due to historical reasons, this unworthy name has been retained until now. There are 22 lunar maria, and there are also some landforms called "lunar lakes" or "lunar maria".

Most of the 22 recognized ones are located on the far side of the moon. , 4 in the marginal area.

The area of ??the lunar sea on the front is slightly more than 50%, and the largest "Ocean Procellarum" covers an area of ??more than 5 million square kilometers, almost the total area of ??nine France. Most lunar maria are roughly circular or oval in shape, and are mostly enclosed by mountains, but there are also some seas that are connected into one piece.

In addition to the "sea", there are five "lakes" with similar topography - Meng Lake, Dead Lake, Summer Lake, Autumn Lake, and Spring Lake, but some lakes are bigger than the sea. It's also big. For example, Menghu Lake covers an area of ??70,000 square kilometers, which is much larger than Qihai and others. The parts of the lunar sea that extend to the land are called "bays" and "marshes", both of which are distributed on the front.

There are five bays: Dew Bay, Summer Bay, Central Bay, Rainbow Bay, and Meiyue Bay; there are three marshes: rotten marsh, plague marsh, and dream marsh. In fact, there is no difference between marshes and bays. The terrain of the lunar maria is generally low, similar to basins on the earth. The lunar maria is 1-2 kilometers lower than the lunar mean level. Some of the lowest seas, such as the southeastern part of the Imbrium, are even 6,000 meters lower than the surrounding area.

The moon's albedo (a physical quantity that measures its ability to reflect sunlight) is also relatively low, so it appears darker. Lunar land and mountains The area on the lunar surface that is higher than the lunar sea is called the lunar land. It is generally 2-3 kilometers higher than the level of the lunar sea. Because of its high albedo, it looks brighter.

On the near side of the moon, the area of ??the lunar land is roughly equal to that of the lunar maria. But on the far side of the moon, the area of ??the lunar land is much larger than that of the lunar maria.

From isotope measurements, we know that the lunar continent is much older than the lunar maria and is the oldest topographic feature on the moon. On the moon, in addition to the numerous jagged craters, there are also some mountains similar to those on the earth.

Mountains on the moon often borrow the names of mountains on the earth, such as the Alps, Caucasus Mountains, etc. The longest mountain range is the Apennine Mountains, which stretches for 1,000 kilometers, but its height is no higher than the level of the lunar sea. Senior year of high school, 4,000 meters. There are also some steep peaks on the mountain range, and their heights were estimated to be too high in the past.

It is now believed that the height of most mountain peaks is similar to that of the Earth's peaks, and the highest peaks (also near the moon's south pole) are only 9,000 meters and 8,000 meters high. There are 6 peaks on the moon above 6,000 meters, 20 between 5,000 and 6,000 meters, 80 between 4,000 and 5,000 meters, and 200 above 1,000 meters.

Mountains on the moon have a common feature: the slopes on both sides are very asymmetrical. The seaward side has a very steep slope, sometimes in the shape of a cliff, while the other side is quite gentle. In addition to mountains and mountain groups, there are four cliffs hundreds of kilometers long on the moon.

Three of them protrude into the moon sea. This kind of cliff is also called "moon moat". Radiation Patterns on the Moon Another main feature on the moon is that some "younger" craters often have beautiful "radiation patterns", which are bright bands that extend in all directions with the craters as radiating points. A straight direction passes through mountain systems, maria and craters.

The radiation patterns vary in length and brightness. The most eye-catching is the radiation pattern in Tycho crater. The longest one is 1,800 kilometers long, and it is particularly spectacular during the full moon. Secondly, the two craters Copernicus and Kepler also have quite beautiful radiation patterns.

According to statistics, there are 50 craters with radiating patterns. The reason for the formation of radial patterns has not yet been determined.

In essence,. 10. Write a composition about the "moon"

When I was a child, I often listened to my grandma telling stories. The one I heard the most was "Chang'e Flying to the Moon". One night, when I had nothing to do, I pestered my grandma to tell stories, and grandma told me the story of "Chang'e flying to the moon" again.

It is said that in ancient times there were ten suns in the sky. The ten suns burned the crops to death and made the people miserable. A hero named Hou Yi, who was extremely powerful and sympathized with the suffering people, climbed up the Kunlun Mountains and shot down nine suns. The last sun was very scared and had no choice but to benefit the people on time.

Hou Yi’s wife is called Chang’e, and they are very loving. One day, Hou Yi met the Queen Mother and asked for a package of elixir. It is said that taking this medicine can make you an immortal, but Hou Yi couldn't let go of his wife, so she said to him: "Give me the medicine, and I will protect it." This scene was seen by Hou Yi's apprentice Peng Meng, who wanted to steal it. Take the elixir and become an immortal. One day, Hou Yi took his disciples to hunt, but Peng Meng stayed behind. He quietly walked to Chang'e's room to steal the elixir. Chang'e tried her best to stop him, but she couldn't fight Peng Meng, so she took the elixir herself. After Chang'e swallowed the medicine, she flew lightly to the sky and became an immortal and went to the Moon Palace.

After listening to this story, I looked up at the moon in the sky, and really wanted to fly into the moon to see Chang'e.

The summer night is so beautiful, with countless little stars blinking in the sky. One day, after dinner, I was playing in the yard with my friends when I saw a bright moon rising slowly. As if shy, the moon revealed its face little by little, emerged from the smoke-like clouds, and sprinkled its little light on the sleeping earth. The earth woke up, and the flowers danced in the dim light. Later, the moonlight became stronger and stronger, and immediately the world became brighter, and we were all illuminated silvery white. At this time, we started arguing again. Some said: "There is Chang'e in the moon to light up for us." Some said: "The crescent moon is caused by the Tengu eating some of the moon." I didn't argue with them and quietly went to my house to check the information. Finally, I found out in a book: The moon itself does not emit light, which is the result of reflection of sunlight. Due to the constant changes in the relative positions between the sun, the moon and the earth, when viewed from our earth, the moon will appear waxing and waning, that is, waxing and waning. oh! The moon is so amazing.

After I came out from home, I told everyone the reason, and my friends understood it.

The night is getting deeper and deeper, but the moon is still so bright
