There are a large number of craters on the surface, as well as a flat lunar sea (i.e., the plains on the moon) and a large number of plateaus (i.e., the yellowish part of the moon).
-
There is a relatively gentle Moon Sea, but there are also mountains with relatively uneven terrain. At the same time, the surface is covered with craters.
-
It is uneven, with a moon sea on the front and a crater on the back.
-
A large number of caves (formed by meteorite impacts) around the mountain have a surface that resembles sandy beaches.

On the moon there are mainly as:
1. Crater, the name crater was given by Galileo. It is a distinctive feature of the lunar surface, covering almost the entire lunar surface. The largest crater is the Bailey crater near Antarctica, with a diameter of 295 kilometers, which is slightly larger than Hainan Island.
A small crater may even be a pothole of a few tens of centimeters. There are about 33,000 of them with a diameter of not less than 1,000 meters. It occupies 7%-10% of the surface area of the moon.
2. Moon Sea, there are 22 moon seas that have been identified, in addition to some terrain called"Moon Sea"or"Moon-like sea"Target. The vast majority of the recognized 22 are located on the front side of the moon. There are 3 on the back, 4 in the marginal area.
3. The lunar land and mountains, the area above the lunar sea is called the lunar land, which is generally 2-3 kilometers higher than the lunar sea level, and it seems to be relatively bright because of its high albetry. On the front side of the Moon, the area of the lunar land is roughly equal to that of the lunar sea, but on the far side of the moon, the area of the lunar land is much larger than that of the lunar sea.
4. Radiant pattern on the lunar surface, there is also a major feature on the lunar surface is some comparison"Young"The craters often come with a beautiful one"Radiant streaks", which is a bright band that extends in all directions with a crater as a radiant point, which passes through the mountain system, the moon sea and the crater in an almost straight direction. The length of the radial streak and the ridge of the bright envy varies, the most striking is the radiant streak of Tycho Crater, the longest of which is 1,800 kilometers long, and is especially spectacular during the full moon.
5. Moon Valley, there is also this kind of foundation on the lunar surface--- those large black cracks that seem to be crooked are the Moon Valley, some of them stretch for hundreds to thousands of kilometers, and the width varies from thousands of meters to tens of kilometers.
6. Volcanoes, lunar volcanoes can be described as old dragon clocks. Most lunar volcanoes are between 3 billion and 4 billion years old; Typical shady plains, 3.5 billion years old; The youngest lunar volcano is also 100 million years old.

The most striking feature of the lunar landform is that its surface is covered with a large number of craters.
The traces left behind by the collision of these celestial bodies, which shine brightly in the night sky, have become one of the main goals of human observation and exploration of the moon.
First of all, the crater of the moon is its most significant geomorphological feature. A crater is a circular crater formed by the impact of celestial bodies, and the energy generated by these impact events can eject rocks and material from the moon's surface into space, forming tiny craters and fissures. The area around the crater tends to be home to mountains, peaks, tunnels, and other geological formations, which are caused by impact events.
Among them, the craters of the Moscow Sea, the Huanhai Sea, and the Rain Sea are the most famous, and their scale is so large that they can be observed on the earth. Craters come in all shapes and sizes, and some are covered with layers of dust or space material on their periphery, creating tunnels and hills of varying sizes.
In addition, there are some obvious layers of material and topographic structures on the surface of the Moon, such as hills, ridges, plates, and hills, which are also derived from the energy and rock ejections caused by celestial impact events. Specifically, hills and ridges are formed by the presence of seismic waves from impacts, while plates and hills are caused by the uplift and folding of the earth's crust.
Overall, the moon's topography is caused by hundreds of millions of years of celestial impacts, crustal evolution, and lava mantle activity. In addition to reflecting the evolution history of the moon over the past hundreds of millions of years, these landform features also provide rich resources and information for human exploration and use of the moon. Therefore, it is of great significance to study and master the geomorphological characteristics of the Moon for understanding the evolution of celestial bodies in the solar system and future space exploration and development.

Analysis: Lots of circumambulation mountains.
The mountains on the moon are undulating, and there are various special names such as ocean, sea, bay, and lake. In fact, there is no water on the moon. The crater is a bowl-shaped pit structure.
There are more than 33,000 craters with a diameter of more than 1 km. Many craters have peaks or clusters of peaks. The faint black spots on the surface of the moon seen by the naked eye are called the Moon Sea, which is a vast plain.
There are 22 of them in the moon sea. The largest is the Storm Ocean, with an area of 5 million square kilometers. Since there is no atmosphere on the Moon, and the heat capacity and thermal conductivity of the lunar surface are very low, the temperature difference between day and night on the lunar surface is very large.
The topography of the lunar surface mainly includes: craters, lunar seas, lunar lands and mountains, lunar radial patterns, and lunar valleys (lunar gaps).
The Moon is the Earth's only natural satellite and the Earth's closest neighbor, and the Moon entered the quiet phase a long time ago, retaining a lot of original information, so it is a good vehicle for studying the origin of the universe. In addition, there are more than 100 kinds of minerals on the moon, 5 of which are not found on the earth, and in the thick dust on the surface of the moon, there is a very important energy source ——— helium-3, which is very rare on the earth and is one of the main raw materials for nuclear fusion. It is estimated that there are 3 million to 5 million tons of reserves, enough to support the earth for 7,000 years. >>>More
There is no air on the moon and sound cannot be transmitted directly, and it is transmitted by radio. >>>More
In general, it is high in the southeast and low in the northwest. In the Pamir region of Tajikistan and the Tien Shan region of western Kyrgyzstan, the mountains are steep at an altitude of 4,000,500 meters, of which the communist peak at 7,495 meters above sea level and Lenin peak at 7,134 meters above sea level are the most famous peaks in the world. In the Karagye depression near the Caspian Sea in western Kazakhstan, the lowest point of 132 meters below sea level has been found on land in the former Soviet Union. >>>More
There are five basic topographic units in the world, which are plains, mountains, hills, plateaus, and basins. The topographic unit refers to a specific area with a large area, and China has the North China Plain, the Tarim Basin, the Qinghai-Tibet Plateau, and so on. So you can't say what the Chinese topographic unit is, dear. >>>More
Biofilms are characterized by fluidity, selective permeability, and asymmetry. >>>More
