The reason for the formation of lunar soil on the moon, what is the surface morphology of lunar soil

The origin of lunar soil refers to:Material**, formation and evolution of lunar soil。It is formed by the melting, crushing and lithification of bedrock at high temperatures due to meteorite impact; A few scholars believe that it may have been formed by some ash flows and rock chips brought by volcanic eruptions.

The temperature of the lunar rock varies greatly, the thermal conductivity of the lunar rock is very low, and its mineral composition and structure are not uniform. The radiation of the lunar rocks by the solar wind and galactic cosmic rays reduces the mineral intensity, deforms the crystal lattice, and may also indirectly promote the formation of lunar soil. In addition, meteorite debris is also one of the important components of lunar soil.

Lunar soil is the moon in real time.

on the soil. And lunar soil is a layer of small particles less than 1 mm in diameter attached to the surface of the moon.

The thickness of the lunar soil covering the lunar surface is less than 1 millimeter in diameter, with sticky fine particles, which vary in thickness throughout the moon, from only a few centimeters in thin places to 5-6 meters in thick places. The lunar soil is loosely structured and consists mainly of rock debris, powder, breccia, and percussion molten glass. The thickness of the lunar soil in the lunar sea area is 4 meters 5 meters, and the lunar land area is exposed to the lunar surface for a long time, and is covered by the sputters formed into craters by previous impacts, so that the lunar soil accumulation is thicker, usually about 10 meters.

How lunar soil is formed.

How lunar soil is formed.

The earth's surface is eroded by air and water, and the hard rocks cannot withstand weathering and turn into soil. Although there is no air and water on the moon, there are other erosion factors. Due to the thermal expansion and contraction of the surface of the moon rocks.

The amplitude is greater than that of the interior; The Moon has no atmosphere.

As a result, the temperature difference between the sun-irradiated area of the lunar surface and the shady place is huge, and the temperature difference between day and night on the moon is huge, and this huge temperature change will cause the fracture of rocks; Ultraviolet rays and X-rays from the sun.

and radiation of rays, solar wind.

and atomic nuclei from the universe that are accelerated to nearly the speed of light.

The bombardment of cosmic rays will destroy the crystalline structure of the rock and cause the rock to fragment. Dust particles from interplanetary space are constantly hitting the moon, and fragments of meteorites are bombarding the surface ...... the moon in turnAll these factors will gradually change the original appearance of the lunar surface, and eventually the vast majority of the lunar surface will be covered by a layer of dust material - lunar soil.

The surface morphology of lunar soil is mainly shaped by impact. Large chunks of bedrock are shattered, mixed, and churned by the impact of small celestial bodies, and finally end up on the moon.

This fine layer of sand is formed on the surface.

The lunar soil looks like a fine layer of cement, with an average particle size of about 100 microns and a thickness of about a few meters to a dozen meters, and is mainly made of olivine.

Composed of minerals such as pyroxene, ilmenite, plagioclase and cemented glass. There are natural mineral particles such as iron, gold, silver, lead, zinc, copper, antimony, and rhenium in lunar soil.

The front side of the moon is dotted with basalt rocks ejected from dark volcanoes.

The lava flow filled with a huge impact crater created a vast plain called the "Moon Sea", in which in fact there was not a drop of water. Between the outer and lunar seas are bright, ancient plagioclase highlands and conspicuous impact craters. It is the brightest object in the sky other than the Sun, and although it appears very bright white, its surface is actually very dark and reflective.

Only the hall is slightly older than the old asphalt.

The surface shape of lunar soil is mainly shaped by impact. Large chunks of bedrock are constantly broken, mixed, and churned by small celestial bodies, eventually forming this delicate layer of sand on the surface of the moon.

Lunar soil is a layer of loosely structured mixture on the surface of the moon, and the basic components of lunar soil include: mineral detritals (mainly olivine, plagioclase, pyroxene, etc.), primitive crystalline rock clasts, breccia debris, various glasses and unique lunar soil components - cohesive agglomerates, meteorite fragments, etc. As a result, the chemical composition, rock type, and mineral composition of lunar soil are very complex, and almost every lunar soil sample includes a variety of lithoburied groups and minerals.

Factors influencing the formation of lunar soil

Generally speaking, there are three main factors influencing the formation of lunar soil:

1. The impact of cosmic dust and meteorites.

2. The continuous bombardment of cosmic rays (solar ultraviolet rays, X-rays, gamma rays, etc.) and solar wind particles destroys the structure of rocks.

3. The large temperature difference of the lunar surface leads to the thermal expansion and contraction of the lunar rocks.

To sum up: lunar soil is formed by the continuous bombardment of meteorites and micrometeorites, cosmic rays and solar wind in the absence of oxygen, water, wind and life activities.

It depends on the information announced, and it is impossible to guess!

The main reasons for the formation of lunar soil are: meteorite impact melts, crushes and sharpens the bedrock at high temperatures; A few scholars believe that it may have been formed by some of the ash flows and rock chips brought by volcanic eruptions.

Lunar soil refers to the unique soil on the moon, and studies have found that there are natural iron, gold, silver, lead, zinc, etc

Copper, antimony, slag rhenium and other mineral particles.

The moon's ancient rocks have puzzled scientists, but they are still young compared to the soil that surrounds them.

According to the analysis, the age of the soil is at least 1 billion years older than that of the rocks. At first glance, this sounds impossible, because scientists believe that these soils were formed after the crushing of rocks. However, after measuring the chemical composition of rocks and soils, scientists found that the soils were very different from the rocks and appeared to come from elsewhere.

Lunar soil refers to the unique soil on the moon, and studies have found that there are natural mineral particles such as iron, gold, silver, lead, zinc, copper, antimony, and rhenium in lunar soil. The structure of the lunar soil is loose.

The formation of lunar soil is closely related to activities such as solar weathering and meteorite impacts. Judging from the fact that Cheng You's song is as good as Zheng, the lunar soil is completely different from the earth's soil. Earth's soil is made up of granular minerals, organic matter, moisture, air, and even microorganisms, but lunar soil is a granular mineral made up of rock debris, powder, breccia, and impact molten glass.

The greatest influence on the formation of lunar soil is the large temperature difference between day and night.

Lunar soil refers to the soil unique to the lunar cavity family, and studies have found that there are natural mineral particles such as iron, gold, silver, lead, zinc, copper, antimony, and rhenium in the lunar soil. Russian scientists have discovered that on Earth, cerium metal is obtained by artificial synthesis, and scientists have never found natural cerium metal. Rhenium metal, like natural cerium metal, is also rare on Earth.

The structure of the lunar soil is loose. Because lunar soil does not contain water and organic matter, it will not condense even if it is stationary.

Almost half of the lunar dust is glassy silica, which was caused by meteors hitting the moon. For billions of years, constant collisions have melted the moon's topsoil into glass, and smashed it into tiny pieces. Lunar dust is rich in metallic elements such as iron, calcium, and magnesium.

In addition, the lunar soil also contains a certain amount of meteorite components, and the analysis shows that the composition of carbonaceous chondrites similar to that of carbonaceous chondrites accounts for about about the lunar soil, and some of the meteorite components are the addition of meteorite components during the early large-scale impact and excavation of the lunar sea basin, some are the addition of meteorite components during the formation of young craters, and some are the addition of meteorite components due to the addition of micrometeorites during the formation of micro-impact craters.

The Moon is the most thoroughly known celestial body. The second celestial body inhabited by humans to this day is the Moon. The age of the Moon is about 4.6 billion years.

The Moon, like the Earth, has a layered structure such as shell,, and core. The outermost lunar crust is on average about 600 to 1,000 kilometers thick. About 1,000 kilometers below the lunar crust is the lunar crust, which makes up most of the moon.

Underneath the lunar core is the lunar core, which is about 1000 degrees Celsius and may be in a molten state. The diameter of the Moon is about 1 km, about 1 4 times the size of the Earth and 1 400 times the size of the Sun. When viewed from Earth, the Moon is as big as the Sun.

The volume of the Moon is about 1 49 of the Earth, the mass is about 1 81 of the Earth, and the gravity of the surface of the Moon is about 1 6 of the Earth's gravity. Did the Moon arise from an epic collision between Earth and a protoplanet the size of Mars? There is no general scrutiny of the theory of this huge collision by scientists, as there are some details that have not yet been confirmed.

For example, the chemical composition of the Earth and the Moon is similar, suggesting that the Moon actually came from the Earth and was not caused by a separate impact. However, other models suggest that the rapidly rotating young Earth may have ejected large amounts of lava during the impact, creating a moon with a similar chemical composition.
