The atmosphere around the Earth is as thin as the Moon, and what has changed in the world

To sum up, it will be like an astronaut landing on the moon.

1. There are changes in temperature, the ozone layer is hollow, and acid rain is in the sky. People will turn into water.

2. If it is difficult to breathe, people have to have a breathing mask, and if it is serious, it will add a new article to the law: the number of oxygen inhalation shall not exceed the limit, otherwise the death penalty will be carried out, and many people should take more oxygen and less oxygen and die. However, the problem of population and the average amount of oxygen taken up has been solved.

3. Ultraviolet rays, solar wind, and cosmic rays are strengthened. However, it is convenient for astronomical observations.

4. Without the protection of the atmosphere, the earth is vulnerable to meteorite impacts, and it will be in the world in the current era of dinosaurs, but it is easier to see meteor showers and other scenery.

5. The magnetic field is reversed, the compass will be dizzy in a short period of time, the compass cannot be sold, and the financial crisis will be repeated.

If so, the end of the world will be repeated: 2012!! The Earth will become a Red Planet like Mars!!

In fact: the ultraviolet rays radiated by the sun will be fully radiated to our body, then our ** will be harmed, and the risk of cancer will also increase.

However, it will be easier for aerospace engineering, because rockets will not need to launch as fast as they do now to fly into space.

1. The temperature difference between day and night on the Earth's surface will be particularly large.

2 The Earth will be particularly vulnerable to asteroid impacts, and the ground will also appear craters.

3. We will be damaged by ultraviolet rays.

4. The air is greatly reduced.

The reason why the Moon does not have an atmosphere is because its gravitational pull is not strong enough to trap gas as an atmosphere.

The most important factor in the formation of the atmosphere is the gravitational pull of the planet itself, that is, the atmosphere is the layer of air that surrounds the planet formed by the gravitational attraction. The mass of the Moon is only one-sixth that of the Earth, so the gravitational pull is only that much. Because the gravitational pull of the moon is too small, it cannot attract the atmosphere, and the atmosphere cannot be successfully formed on the moon.

Although the Moon has a very small and thin atmosphere, it is too small to have a successful atmosphere. The moon's atmosphere comes from the gas released by itself and the gas produced when meteors hit the moon, but these gases are basically not retained by the moon, and most of them are carried away by solar wind and solar radiation.

Another example is Mars, the gravitational pull is also relatively small, but it is larger than the moon, so it has a relatively thin atmosphere, and Jupiter, the gravitational pull is abnormally large, so the atmosphere is very thick.

Moon temperature characteristics.

Because the moon has no atmosphere, it has a large temperature difference, the highest temperature can reach more than 100, and the lowest temperature is only more than minus 100, so in general, the lunar environment is quite harsh. <>

The main reason why the Moon has no atmosphere is that its own mass and gravity are too small to maintain a stable atmosphere. The Moon is subjected to more intense solar radiation and cosmic rays than the Earth, and is less affected by the Earth's gravitational pull, which makes it impossible for the Moon to maintain its atmosphere.

The Earth's atmosphere is mainly composed of gases such as oxygen, nitrogen, carbon dioxide, and water vapor, which are attracted by the Earth's gravitational field and held around the Earth, forming a stable atmosphere. However, the mass of the moon is relatively small, its gravitational field is relatively weak, and it cannot form a stable atmosphere, and because the rotation speed of the moon is very slow, its surface temperature difference is large, and it cannot form a stable troposphere.

In addition, the topography of the lunar surface is also one of the factors affecting its lack of atmosphere. The rocks and soil on the Moon's surface are loose and unable to absorb gases from the atmosphere, making it impossible for the Moon to form an atmosphere on the surface.

In summary, the reason why the Moon has no atmosphere is mainly due to its own mass and gravity that is too small to maintain a stable atmosphere, as well as the influence of surface topography. This is one of the reasons why there is no liquid water and no life on the surface of the moon.

By learning about astronomy, we can know that the earth is surrounded by an atmosphere around the earth, so why is the moon, which is also a planet, surrounded by an atmosphere? In fact, because the mass of the Moon is smaller than that of the Earth, the Moon's gravitational pull on other substances in the universe is also small, so it cannot attract some gases in the universe to its surroundings.

1. The formation of the earth's atmosphere: The atmosphere around the earth is from the primordial atmosphere to the secondary atmosphere, and finally to the current atmosphere. In the beginning, in the process of its own formation, our earth began to revolve around the sun, and then used its gravity to absorb some gas and dust molecules in the universe. As the amount of absorbed matter increases, the mass of the earth gradually becomes larger and larger, and its gravitational pull becomes larger and larger, and the surface of the earth begins to gradually become solid, and the earth is surrounded by an atmosphere.

And this atmosphere is what we call the primitive atmosphere, and its main components are helium and hydrogen. Later, due to the frequent movement of the earth's crust, volcanic eruptions were very frequent, and the gases emitted from the volcanic eruptions condensed together to form the Earth's secondary atmosphere, which is mainly composed of methane and hydrogen. Then with the advent of humans and various organisms on Earth, the Earth formed its current atmosphere.

2. Introduction to the Moon The Moon, also known as the Moon, is a natural satellite of the Earth and a satellite in the solar system. But the Moon is smaller than the Earth and also has a much smaller mass than the Earth. Its surface has many craters formed by the impact of other small celestial bodies.

The moon appeared shortly after the formation of the Earth.

3. The reason why the Moon has no atmosphere is that the Moon is also a planet in the universe, so why there is no atmosphere around it. In fact, the reason is very simple, because the mass of the moon is small, the gravitational force is small, and the speed of the objects around the moon is relatively large, so it is very easy to break free from the gravitational pull of the moon, resulting in the moon not forming an atmosphere.

Because the earth has a layer of soil, oxygen, abundant water, and a biosphere, these are the conditions that can produce an atmosphere, and the moon does not fully have these conditions.

Because the Earth has the conditions to generate an atmosphere and the Moon does not have these conditions, there is an atmosphere on Earth and not on the Moon.

The main reason is that the mass of the moon is too small to absorb the atmosphere, and the other is that there are no gases of various components on the moon, and there are various complex gases such as oxygen, carbon dioxide, methane, and hydrogen on the earth.

In addition to the Earth, there are also Venus, Mars and Titan (the only moon in the solar system with an atmosphere), except for these celestial bodies, the others are either gaseous planets or lone planets, such as Mercury, and Pluto, of course, Pluto is no longer a planet! So why does the moon not have an atmosphere when a celestial body so close to the earth has it? After all, the earth's atmosphere is so rich, can't it be evenly given to the moon at the beginning of its formation?

In fact, whether a celestial body can retain the atmosphere is not to see whether the gas elements around it are abundant, but whether the gravitational force generated from its mass can retain the atmosphere.

1. The orbiting velocity and escape velocity of the Moon.

The Moon is the closest natural celestial body to the Earth, and its main parameters are as follows:

Lunar diameter: km.

Moon mass: kilograms.

To put it simply, the first cosmic velocity is the "centrifugal force" generated by the circumferential velocity of the object orbiting the celestial body, which is equal to the gravitational pull of the celestial body on it, so as long as this speed is maintained, the object can remain in this orbit all the time!

Second, the cosmic velocity, which is the speed at which an object orbits a celestial body, produces a centrifugal force that exceeds the gravitational force that binds it, and it is gone!

Only if the temperature is above absolute zero (, then the thermal motion of the molecule will never stop, of course, the molecular motion also has a velocity, and as long as there is a velocity, the corresponding "centrifugal force" will be generated, and they also abide by the relationship between the "centrifugal force" and the gravitational force!

If we want to know this answer, first of all, we must understand that the mass of the moon is 1 81 of the earth, that is to say, the moon does not have enough mass, in the case of insufficient mass, naturally its gravitational force is very small, without this kind of force, it will not be able to restrain the thick atmosphere around it, without the atmosphere, you can imagine what the result will be, and there will definitely be no life.

Having said a lot, I don't understand why the moon doesn't have an atmosphere? You know, the so-called atmosphere, the gas molecules in it are moving around and colliding with each other, these collisions and interactions, what does that mean? At any time, if there is a certain volume of gas, there will be a certain range of gas molecule velocity in it, and in this range, these molecules will be filled one by one.

To tell you a little bit, there will be a small part of the molecule that will move very slowly, and the other part will be close to an average velocity. There are some molecules, it will move very fast, and these fast-moving molecules, which are the molecules that are pressurized by the collision, they don't hit anything else to slow down, and when the gas is reheated, you will find that its range becomes larger. What would happen if our astronauts flew to the moon and released a tank of nitrogen on the moon's surface?

You'll see some of the gases, they're moving slowly enough not to get out of the moon's gravitational pull for a split second, but there's still a small part of the gases that move fast enough. In this way, the gases that do not escape completely will reach a high lunar orbit and further interact with the particles of the solar wind and dissipate. The populations that have lost their fast-moving gases will be replaced from their original populations until almost all of the gases are slowly gone.

So the surface of the moon, as we see it now, is in a vacuum, and even if you start with a 10 kilometer thick atmosphere, under the pressure of one atmosphere on the entire surface of it, then it will come back to a state in a few hours, and now this state will slowly spread out and be blown away. We know that without the atmosphere, the environment would be very cruel, there would be no living thing to breathe freely, and certainly nothing would keep the water in a liquid state. Just like our understanding of life today, there is no way to produce it there.

Whether a planet has an atmosphere is determined by a variety of reasons It is not caused by the difference between satellites and planets, but mainly due to the three points of mass and magnetic field strength and distance from the star The mass of the moon is too small The gravitational force is also weak, and the small escape speed is difficult to retain gas to form an atmosphere, plus the magnetic field strength is not enough, and it is too close to the star, so the solar wind can sweep through and take away the atmosphere Although Mars is a planet, it has no magnetic field protection, so the atmosphere becomes very thin under the influence of the solar wind The moons of Saturn, which are farther away, have a thick atmosphere Therefore, whether or not they have an atmosphere is not related to the division of planetary moons, but to mass, gravity, distance, and magnetic field ps: The Moon is not an absolute vacuum, but the vacuum is very low (:

The Moon is too small, only one-sixth the mass of the Earth, to form an effective gravitational force to retain the atmosphere.

The atmosphere protects us from ultraviolet rays.

The environment of the moon is different from that of the earth, the air structure, soil structure, and ecological structure are different, and it is normal that there is none, and if there is, maybe some people will immigrate to the moon.

The structure of the Earth and the Moon is not the same. The earth has an atmosphere, it has air. Hey, the moon doesn't? The earth is. Wake up, the Moon is a satellite.

Because the gravitational pull of the moon is too small, plus there is no water.

Why do you still buy a set of 100,000 why.

To put it simply, the moon is too small for gravitational enough.

The Earth is a planet and the Moon is a satellite

You can't just get close to each other and the structure is the same.

The Earth has gravity, the Moon has no gravity.

I'm glad you asked, I've read about the Moon, and it's not that the Moon has a thin atmosphere, it's that it doesn't have an atmosphere, and the reason is that the Moon is light, and it doesn't have a big attraction to absorb the atmosphere.

If there is no atmosphere on Earth and will turn into a situation of the Moon.

1。The temperature difference between day and night is very large, more than 200 degrees during the day, more than 200 degrees below zero at night, and the difference is 400 degrees, which is the temperature difference between day and night on the moon.

2。The earth is likely to be unrecognizable, meteorites and small stars in space may hit the earth at any time, and the earth is protected by the atmosphere, and meteorites and other materials will burn when they rub against the atmosphere in high-speed motion, and then they will not harm the earth, and the moon is full of traces of space material impact.

3。Radiation is very harmful, and without the protection of the atmosphere, radiation can harm people at any time, and if it is a sunspot explosion, it is unimaginable.

4。There is no more blue sky, white moon, blue is too difficult, and white clouds are all phenomena of the atmosphere.

5。The water cycle is difficult Life on Earth lies in the water cycle There is only evaporation and no rainfall, how can life survive.

6。There is not enough air, there is not enough oxygen, humans cannot breathe, other air disappears, sound cannot travel, and the earth will be dead.

If there was no atmosphere, life would cease to exist, but rest assured that this is not going to happen at the moment.
