We live on the surface of the earth, living above the earth's crust, but there is a thick atmosphere outside the earth's crust, the thicker part of which is about 100 kilometers thick, and the upper part is relatively thin, mainly belonging to the ionosphere in the atmosphere, this part of the gas is easily blown away by the solar wind, and some scientists have found that the earth's atmosphere blown away by the solar wind every year may be as much as 101 million tons.
Why does the solar wind blow away the Earth's atmosphere? This is because the speed of the solar wind is very fast, it is originally a gas ejected from the surface of the sun, under high temperature and high pressure their speed can reach 500 1000 kilometers per second, this gas is mostly ionized hydrogen and helium elements, so that when they come to the vicinity of the earth, such a high speed hits the outer atmosphere of the earth, it will blow away a part of the gas, and the mass of the earth's atmosphere is mainly reduced from this.
However, the earth also has a set of mechanisms to protect the atmosphere, that is, the earth's own magnetic field, the force of the earth's magnetic field is far away from 70,000 kilometers, so the solar wind is still far away from the thick part of the earth's atmosphere, and it will interact with the earth's magnetic field, because the solar wind is ionized gaseous matter, so the earth's magnetic field can prevent it from hitting the earth's atmosphere, so that they are delayed to blow away in both directions, and some of them will enter the earth's polar regions to form a spectacular aurora.
However, despite the protection of the Earth's atmosphere by the Earth's magnetic field, the Earth's atmosphere is still blown away by solar winds every year by 101 million tons of atmospheric matter. This value seems very large, but in fact it is very small relative to the total mass of the earth's atmosphere, but if it is calculated in hundreds of millions of years, the loss of atmospheric mass will be very large, because the earth has been formed for about 4.6 billion years, and if it is lost so much every year, there will be no atmosphere on the earth for a long time, why is the earth's atmospheric mass not decreasing?
The reason is also very simple, that is, while the earth loses some air, it will also capture and absorb some air, which includes two ways, the first is to lose it and pick it up. Because in the orbit of the earth, there are atmospheric molecules that were lost during the earth's orbit, and when the earth recircles, they will be captured.
The second way to capture is the auroral phenomenon mentioned above, the earth's magnetic field concentrates the solar wind from the direction of the magnetic field lines to the poles, and this part of the solar wind will also be captured by the earth and become part of the earth's atmosphere.
Therefore, these operation and operation mechanisms of the earth also ensure the balance of the earth's atmosphere, which loses so much air every year while replenishing so much air, so the earth's atmosphere is basically always in a state of neither increase nor decrease, which also ensures the harmonious development of life species and ecological environment on the earth's surface.
-
That's because the ozone layer exists on the earth, which protects the gas from decreasing.
-
While the earth loses some air, it also captures and absorbs some air.
-
Because although he will lose gas, he will also replenish gas all the time.
-
Because matter is circulating, it will replenish air in other ways.
-
Because while it loses millions of tons of air, it replenishes at the same time.
-
It loses so much air every year and replenishes so much air.
-
Because there will still be oxygen, so many plants will also produce oxygen.
-
Because the air that the region loses every year is also produced by the plants.
-
Most of the gases are still attracted by the Earth's gravity and cannot escape from the Earth.
-
The earth is not a sealed place, and some will also enter the universe.
-
This is our earth, a world full of life, the only place where human beings are currently known to have life. The reason why the earth can become the only planet with life, in addition to the right space location and the right magnetic field of the right strength, the most important thing is that it is wrapped in a thick atmosphere.

Do you know how heavy the ball weighs? According to the calculations of scientists,The mass of the Earth is about 60 trillion tons. But the mass of the Earth is not static, there is one above the Earthatmosphere,The mass of this atmosphere is significant.
ButThe farther away from the Earth, the less the gravitational pull of the Earth will be, so the atmosphere that is far away from the earth will continue to be lost every day, which is equivalent toThe Earth loses thousands of tons of atmosphere every day。So since that's the case,Is the mass on Earth decreasing? This is not the caseAlthough thousands of tons of the Earth's atmosphere disappear every day, there are many factors that increase the mass of the Earth.
The first is lightAlthough light is a kind of energy, it seems to us that light has no mass, but after it has been absorbed by plants on the earthEnergy can also be converted into mass。Because the plants of the earth contain:Chlorophyll,Chlorophyll can be carried outPhotosynthesis,Converts sunlight into nutrients that are stored in one's own body and become mass. Although this mass is relatively small, when all the plants are combined, this mass is very large.
On the contrary, if it is, it willMass is converted into energyThen the energy is quite huge, for exampleThe United States dropped two atomic bombs on Japan。These two archetypal summoning bullets are actually onlyA gram or somass loss, but when they are converted into energy, they can be generatedHiroshima and Nagasaki, JapanThe power of destruction on two large islands.
The second type is the particles in the universeAlthough the Earth loses thousands of tons of atmosphere every day, the Earth also attracts many other materials because the Earth also hasSuctionTarget.
In fact, as we mentioned above, plants can photosynthesize, convert energy into mass, and the earth will also absorb many particles in the universe. But these two factors have a negligible effect on the mass of the Earth, and can even be ignored, because the mass of the Earth is simply too largeThe increased mass is a drop in the bucket for the Earth
But there's another way to gain weight faster for the planet, and that's thatMeteorites from beyond the sky。Since the beginning of the earth, there have been many alien objects that have the potential to reach the earth at any moment and form after frictional reactions with the earth's atmosphereBeautiful shooting stars。These meteorites are large and small, and the mass is not the same, but usuallyThey become a part of the Earth as soon as they reach it
So so farThere are a lot of meteorites accumulated on the earth, which can play a role in increasing the mass of the earth.
Although the mass on Earth increases from moment to moment, there are many factors that contribute to the increase in mass on Earth. ButRelative to the mass of the earth itself, their increase will not have a substantial change in the earth。In addition, not all meteorites will have a valuable impact on the Earth after they reach the Earth.
Because the value of these meteorites, according to theirThe quality and hunger oak materials and the places they come from are differentThere will also be differences, so not every meteorite is of great value. For now,Meteorites that come to Earth from the Moon and Mars are of the highest value.
-
The reason why the earth loses thousands of tons of air every day, but the mass does not decline, is that although the earth disappears thousands of tons of atmosphere every day, there are also many factors that will increase the mass of the earth; One is that light energy can be converted into mass, and chlorophyll can be photosynthesized; The particles in the universe, the earth will attract many other substances, because the earth has an attraction; There are many meteorites accumulated on the earth, which can play a good role in increasing the mass of the earth.
-
Because many people are now paying great attention to the protection of the environment, and the family has also done a lot of things to protect the environment, the air quality has not decreased significantly.
-
That's because the earth is producing air when it loses air, and it remains in a conserved state.
-
Because the air is in the air and does not count as the mass above the Earth, it has no effect on the mass of the Earth.

According to relevant research institutions, under the action of solar flare eruptions, the solar wind blows in all directions at a speed of 350-1,000 kilometers per second, which is more than 10,000 times the fastest wind speed on the earth. When the solar wind blows towards the surface of the planet, if there is an atmosphere on the surface of the planet, the solar wind will transfer kinetic energy to the atmospheric molecules, making the atmospheric molecules flow quickly, and if the escape velocity is reached, it will break away from the constraints of the planet's gravity, causing atmospheric attrition, which is why solid planets such as Mercury and Mars in the solar system have no atmosphere on the surface or have very thin atmospheres.
<>Because the mass and volume of the earth's mass and volume of material ** is a large amount of dust flow material released by the continuous nuclear fusion combustion process of the sun, it continuously provides inorganic substances for the space of the solar system and provides an effective guarantee for the gradual formation of various planetary bodies in the space of the solar system. Regardless of whether the mass of the earth has changed or not, the key is to find out if there is new matter. Because the Earth will be hungry to capture the debris of alien objects, such as comets and other unburned objects and meteorites, but it will be difficult for the material on Earth to escape the attraction of Earth and fly out of Earth.
As a result, the mass of the earth is increasing. However, it would be wrong to say that the photosynthesis of plants on Earth will lead to an increase in the mass of the Earth. Because photosynthesis uses water, carbon dioxide, and other elements to synthesize organic matter, and water, carbon dioxide, and other elements are substances on earth.
However, in addition to bringing tsunami, ** and volcanic eruptions, the biggest hidden danger comes from changes in the magnetic field. The cause of the Earth's magnetic field has not yet been determined, but it is likely to be related to the inconsistent rotation speed of the Earth's inner and outer layers, since the Earth's outer core is a liquid. It is not clear what will happen to the outer core when the rotation of the Earth's outer layers stops, but the magnetic field may inevitably change dramatically.
If the magnetic field weakens or disappears, it is conceivable that the solar wind will blow directly towards the ground.
Whether the mass of the earth has changed or not, it is important to find out whether there is any new material. Because the earth will capture the debris of extraterrestrial objects, such as comets and other unburned materials, meteorites will fall, but it is difficult for the materials on the earth to escape the attraction of the earth and fly out of the earth. As a result, the mass of the Earth is increasing.
-
This does not mean that the mass of the Earth is declining, because the Earth also gets matter and energy from the universe.
-
It does not mean that the mass of the earth is declining in the age of the base code, but it can only be said that these atmospheres are normal losses, because the organisms living on the earth are very reputable, so these atmospheric losses are very normal.
-
I think this means that the mass of the earth is declining, so I think this situation is very dangerous.

The Earth's atmosphere loses 100,000 tons per year. Why does the total amount of the atmosphere stay the same? Scientists give the answer With the continuous progress of human science and technology, we know that there is an atmosphere on the earth, and it is because of the atmosphere that life can exist on the earth.
Why do you say that? For billions of years since the birth of the Earth, the atmosphere has been like a protective film, clinging to the Earth.
In addition, the atmosphere is protected from direct sunlight and various ultraviolet rays in the universe. The atmosphere worked very well. So why is the atmosphere always present on Earth?
The first is because there is gravity, the earth has its own gravity, so the atmosphere can be firmly absorbed by the earth, and the atmosphere as a very light existence!
It is found in the outermost layer of the Earth, and the atmosphere will gradually become smaller as the distance increases. That's why when we reach high altitudes, we always feel that the air is thin and there is a lack of oxygen. So far, there is no precise statement about the thickness of the atmosphere.
However, scientists have always believed that the thicker part of the atmosphere is closer to 50 kilometers. With the discovery of scientists, scientists have discovered this almost every minute through observation. Almost 180 kilograms of the Earth's atmosphere is blown into the universe, which is still a fairly conservative number, but even then, the Earth's atmosphere can still remain in equilibrium!
According to scientists' calculations, the Earth's atmosphere loses almost 100,000 tons per year. According to the calculations of scientists, the total mass of the Earth's atmosphere is about 60 million tons. If compared to the total mass of the Earth, it is almost one millionth of the total mass of the Earth.
As a result of the eruption of a solar flare, the solar wind blows quickly towards the Earth. When these solar winds blow some of the gases in the atmosphere at a speed of 500 to 1,000 kilometers per second, it will leave the Earth and enter the universe under the action of the solar wind. However, because the Earth revolves around the Sun, most of the Earth's atmosphere disappears, and the Earth will also capture a large amount of gas that was previously left in orbit!
-
Then our atmosphere is in circulation, so there will be a new atmosphere.
-
Because the earth is still producing all these gases.
-
Because although there is a loss, there is still a certain replenishment of the atmosphere, so the total amount will not change.
No, the time will not increase.
