1. Exploring the Mysteries of the Moon, a 600-word essay for the first grade of junior high school.

The moon is a mysterious star, an incredible topic, and a fantasy world. Today, in our class meeting, let us explore the mysteries of the moon.

The moon basically has no water, so there is no weathering, oxidation, and water corrosion processes on the earth, and there is no sound transmission. There is a silent world everywhere. The moon itself does not emit light, the sky is always dark, and the sun and stars can appear at the same time.

There is almost no atmosphere on the moon, so the temperature difference between day and night on the moon is very large. During the day, in places where the sun shines vertically, the temperature is as high as 127°C; at night, the temperature can be as low as -183°C. Because there is no atmospheric barrier, the intensity of sunlight on the moon is about 1/3 stronger than that on the earth; the intensity of ultraviolet rays is also much stronger than that on the earth's surface. Because the moon has a small atmosphere, many strange phenomena will be seen on the moon. For example, the sky on the moon is dark and black, and the sunlight is straight. The places where the sunlight shines are very bright; the places where the sunlight does not shine are very dark. That's why we see the moon's surface as bright and dark. Stars no longer appear to twinkle on the moon because there is no air to scatter light.

The moon is full of exposed rocks and silhouettes of craters. The entire moon surface is covered with a layer of gravel and floating soil. The lunar surface as seen from Earth has bright areas and dark gray parts. It turns out that the bright parts are the mountains and highlands on the moon's surface, and the dark gray parts are the plains on the moon's surface.

The moon is smaller than the earth, with a diameter of 3476 kilometers, which is approximately 3/11 of the diameter of the earth. The surface area of ??the moon is about 1/14 of the earth's surface area, which is slightly smaller than the area of ??Asia; its volume is 1/49 of the earth. In other words, 49 moons can fit inside the earth. The mass of the moon is 1/81 of the earth; the average density of material is 3.34 grams per cubic centimeter, which is only equivalent to 3/5 of the earth's density. The gravity on the moon is only 1/6 of the earth. In other words, something weighing 6 kilograms will only weigh 1 kilogram on the moon. When a person walks on the moon, his body seems very relaxed, and he can jump up with a little effort. Astronauts think that walking on the moon, half jumping and half running, seems more enjoyable than walking on the earth.

The moon is the closest celestial body to the earth. It is a natural satellite orbiting the earth. Its average distance from the earth is about 384,400 kilometers. The Moon's orbit around the Earth is a circular orbit, with an average distance of 363,300 kilometers from its perigee (when it is closest to the Earth) and an average distance of 405,500 kilometers from its apogee (when it is furthest from the Earth), a difference of 42,200 kilometers.

The moon is really beautiful and mysterious.

It is now 20xx. If you count carefully, I am already two hundred and thirteen years old. My mom is on vacation on the moon and I'm going to find her.

I completed the formalities and arrived in Beijing by flying chair. Immediately afterwards, I boarded the Chang'e No. 88888. As soon as I sat down, I took a sip of water and looked out the window - where are we? I got off the spacecraft and what I saw was a sign that said "Welcome to the Moon Village".

oh! I've reached the moon! However, the last time I took a spaceship, it took three seconds! Oh, it must be speeding up again!

The purpose of my trip is to find my mother! So, I used the Beidou satellite positioning system to search. strangeness? It didn't happen, and I was puzzled - couldn't it be broken? I have to find someone quickly. So, the flying chair started, and there was a small town in the distance. I arrived there in an instant and started asking for help.

The people here are very strange. They are like robots - without emotions. Everyone is stiff. When I was looking at them carefully, some people walked out of the huge crowd and walked directly in front of me, as if they wanted to arrest me. At this time, one of them spoke: "Come on!" My guess was correct - they were going to arrest me! In desperation, I fired the laser, and the person I hit suddenly fell to the ground and turned into a robot.

More people came to arrest me. I had no choice but to launch a missile, but in the Thirty-six Strategies, walking was the best. After they fell to the ground, I ran away in a hurry, taking one with me by the way. robot. I came to a high mountain and started researching in a secluded place. I invaded his brain with a computer and started to analyze it. Finally, the hard work paid off. I knew: after they captured the earthlings, they merged an earthling and a robot, and there was a new person. This person possessed the characteristics of the earthlings. body and robot consciousness. Seeing this, I suddenly thought of one thing: If the mastermind of this matter was placed on the earth, wouldn't the earth belong to him? I dare not think about it anymore! How terrible! So, I immediately reported the incident to Earth Headquarters and asked them to send troops to support me. For the sake of the safety of the Earth, they agreed.

While waiting for reinforcements, I searched for the robot headquarters. Standing on a high mountain, I saw it all at once. When I flew there, I found a big cage inside with many earthlings in it, including my mother. In order to rescue the people on earth, I came up with a way: let them wear robot-like clothes. So, I immediately conjured up a large number of clothes worn by the robots, sent them to the cage in an instant, and informed them. Just as they were getting dressed and starting to flee, reinforcements arrived.

Just after the last earthling came out, I gave the order: "Fire." The robot headquarters was immediately exploded. At this time, I also found my mother. Mother and son hugged each other tightly, not knowing how much we wanted to say.

The moon is a natural satellite of the earth. In an era when science and technology was underdeveloped, literati always gave the moon the most romantic color. There were even stories among the people about Chang'e flying to the moon and Wu Gang cutting down the osmanthus tree. When our ancestors faced unknown things, they always had many associations and stories. They also called the moon Taiyin, Xuantu, Chanjuan, and Jade Pan to express their thoughts.

The invention of the telescope gave mankind a better understanding of the exploration of the moon. People found that the surface of the moon was uneven, but at that time people did not know what was on the back of the moon. When humans first set foot on the moon, Neil Armstrong said something that made all mankind excited, "That's one small step for man, one giant leap for mankind."

People discovered the surface of the moon It is full of small craters, which are formed by the impact of other meteorites. Because the surface of the moon is not protected by the atmosphere, when meteorites in the universe pass by, they will hit the surface of the moon and form small craters. The moon is a relatively small satellite in the solar system. It only revolves around the earth. So actually we can see the moon every day, but the moon itself does not emit light. The reason why we can see the moon at night is because it reflects the light of the sun, so we can see it at night. In fact, the moon is always hanging In the sky, I just don't see it during the day.

There are many theories about the birth of the moon. There are currently four more convincing theories. The first is the split theory. This theory was proposed by Darwin's son George. He believed that the moon was originally a part of the earth. Later, because the earth rotated too fast, part of the material on the earth was thrown out, forming the moon. However, this statement was quickly debunked by others.

The second theory is the capture theory. They believe that the moon is attracted by the gravity of the earth, but some people think that the earth may not have that much power to attract the moon. The third theory is the theory of homology. They believe that the earth and the moon are both diffuse nebula materials in the solar system. They have rotated and accreted in almost the same solar nebula area, and formed celestial bodies of different sizes at the same time. But this statement is also questionable, because the rocks on the moon's surface are much older than the rocks on the earth's surface. There is another theory called the collision theory, which is more complicated. It means that when a celestial body collides, the moon is formed by the combination of the colliding celestial body and the material that fell from the earth, but it cannot escape the gravity of the earth. Thus the moon was formed.

Human beings have never stopped exploring the moon. my country's Chang'e 5 also successfully landed on the moon and sampled the rocky soil on the moon's surface. The moon is the closest celestial body to us and the first step in our exploration of the universe. Maybe in the near future, we can all visit the moon.
