After the Earth stops, its magnetic field, which is created by the rotation of the iron core of the planet, will disappear.

It should be clarified that the instantaneous stop of the Earth's rotation is practically impossible. It will still slow down for a while. But if you imagine that the Earth suddenly stops, then you can imagine the following scenario.

As is known from the school geography course, under the earth's crust is its mantle and core. They rotate in the opposite direction to each other. With a sudden stop of the globe, the core and mantle will rotate several times, crushing and breaking the entire lithosphere. As a result, powerful earthquakes with many kilometers of faults and volcanic eruptions will occur. This will lead to the mass extinction of all life on Earth.

In addition, the atmosphere of the planet will also rotate around the globe. And since its rotation speed will be the same as that of the Earth, amounting to about 500 m / s, and a little later it will increase several times, then such a colossal wind will blow away all living and inanimate objects from the surface. In this case, everything will fly to the east. The water in the oceans will also flow in this direction, and by inertia, forming a giant tsunami. Due to the force of inertia, a complete or partial loss of the atmosphere is not excluded. At the same time, the kinetic energy of the Earth and the same inertia force can simply tear the planet to pieces.

If the stop occurs smoothly, then the scenario will be slightly different. Centrifugal forces compress the Earth at the poles, creating a hill at the equator. At the same time, the diameter of the planet there is 43 km larger than at the poles. If there is a stoppage of rotation, then this elevation will disappear, and all the oceans will flow towards the poles. There will be a global distribution of land and water. In this case, two separate oceans are formed - the North and South. And along the equator, taking into account the tilt of the earth's axis, one continuous continent is formed, encircling the Earth.

There will be a complete change in the course of day and night and the change of seasons on the planet. Until the Earth makes a complete revolution around the Sun, a day on earth will last one year! The concept of seasons will disappear. Now there will be only the seasons of the day - night, morning, afternoon and evening. The climate will also change. During the day it will be warm on Earth, and at night it will be frosty.

In a different temperature regime, winds will begin to blow from the equator to the poles, and not be distributed parallel to the equator, as they are now. Climate change will also occur due to changes in the movement of underwater currents, which will lead to global changes in marine ecosystems.

After the Earth stops, its magnetic field, which is created by the rotation of the iron core of the planet, will disappear. Now its surface will not be protected from solar wind radiation and from high-energy particles from deep space. If, after global catastrophes, some species of animals, plants, and humans still survive, they will undergo numerous mutations.

By the way, in reality, the Earth actually slows down its rotation. Due to tidal forces between it and the Moon every 100 years, the day becomes longer by 1.5–2 milliseconds. In 140 million years, there will be 25 hours in an Earth day.

We know perfectly well that our planet rotates around its axis, thanks to which we see day and night. However, the Earth, although very slowly, is gradually slowing down. Scientists say that it will stop completely in many billions of years. People will probably not catch this moment, because by that time the Sun will increase in size and destroy first life on Earth, and then the planet itself. In this article, we will try to simulate the following situation: what will happen if the earth stops rotating in the foreseeable future.

Why does rotation happen at all?

According to the generally accepted theory, the rotation of the Earth is due to processes that took place even at the time of its formation. In those days, clouds of cosmic dust huddled into one "heap", to which other cosmic bodies were attracted. As a result of this confusion, the planet formed over billions of years. And its rotation is due to the inertia that remained after the collision with those very cosmic bodies.

Why is the Earth slowing down?

At the dawn of its existence, our planet rotated much faster. The day then was about 6 hours. The opinion became popular, then most of all the change in the speed of the earth's rotation is influenced by the moon. With its force of attraction, it causes fluctuations in the water level in the earth's oceans. Because of the tides, the Earth seems to sway, which leads to its very slow deceleration.

What would happen if the Earth suddenly stopped?

Yes, this option is almost unbelievable, but why not?

Today, the speed of rotation of the Earth is no less than 1670 km / h. With the sudden stop of the planet, everything that was on its surface, including people, will be instantly swept away due to the effect of centrifugal force. In fact, the Earth will stop, and objects on its surface will continue to move.

This option is perhaps more acceptable to people, because everything will happen so quickly that no one will understand anything. But in the case of the gradual deceleration of the Earth, we will have to experience many devastating consequences.

What will happen if the Earth gradually stops its rotation?

Now let's move on to a more realistic simulation of the situation, if our planet began to slow down much faster and humanity still caught the moment of its stop.

We already know that our planet will stop only in billions of years, but hypothetically it could happen even earlier. Scientists do not exclude that the planet's rotation speed may decrease, for example, due to a collision with an asteroid. Such an event in itself would be disastrous for earthlings, and a slowdown in the planet's rotation would be an unpleasant bonus to everything. But let's imagine that this happened without the participation of huge asteroids, but for more "invisible reasons."

Light and darkness

The first thing that comes to mind is eternal day on one hemisphere and eternal night on the other. In fact, these are trifles compared to other global changes, ranging from terrible cataclysms to the redistribution of the waters of the oceans, which will lead to the mass death of all life on the planet.

The concept of day will disappear. On one side of the Earth there will be eternal day. At the same time, constant sunshine will destroy many plants, and the soil will dry out and crack. The dark side of the Earth will be like a snowy tundra. Scientists believe that an intermediate region between day and night will be more or less suitable.

Equator without oceans

The waters of the oceans will change their location, shifting from the equator to the poles. I.e the equatorial line will become one large piece of land, and many continental zones closer to the poles will be flooded. The fact is that our planet is slightly convex due to rotation, so it has a kind of “hump” along the equator. Thus, after the Earth stops, the waters of the World Ocean will cease to be evenly retained and will actually “drain” from the equator.

Climate and the habitability of the planet

In addition to the fact that land and oceans will look different on Earth, the climate will also change dramatically. Right now the winds are blowing parallel to the equator, but if what happens happens, they will blow from the equator towards the poles. The trends will naturally change. It is difficult to say what climatic conditions will be in a particular region, but you can be sure that one hemisphere will be arid, and the other incredibly cold.

The atmosphere of the Earth, like ocean waters, will become denser closer to the poles, and thinner at the equator.

Due to the fact that the metal core of the Earth rotates, there is a magnetic field around it. It provides protection from the destructive solar wind and from high-energy particles from space. Without rotation, there will be no magnetic field, and therefore, all living things will die under direct sunlight.

Among the representatives of animal and plant species will be inevitable. Flooding of large areas, climate change, natural disasters - all this will clearly reduce the diversity of life on Earth.

Can people survive?

Certainly people would be able to adapt to the new conditions. There aren't many places left to survive. People will be able to live in small areas on the border of day and night. In such places there will be an eternal dawn or sunset, depending on the hemispheres. In addition, it will not be possible to settle along the entire “favorable line”, since a large part of the land will be flooded by oceans, and you will have to choose an area where there will be optimal atmospheric pressure and temperature.

It is possible that due to dangerous cosmic radiation, people will have to move underground and organize their life activities there, and spacesuits will be needed to walk on the surface.

Conclusion
Thanks to such a familiar phenomenon as the rotation of the Earth around its axis, we can exist quite comfortably. In general, it is worth thinking more often about what surrounds us, because outside our planet, hundreds of millions of light-years away, not a single place has yet been found with ideal conditions for humans.

The fact that the Earth constantly rotates around its own axis, which is why there is a change of day and night, today, perhaps, even younger students know. But about what will happen if our planet stops rotating, physicists told. In our review, the most incredibly catastrophic scenarios for the development of events

1. People will feel like they are on a roller coaster.

The speed of rotation of the Earth is approximately 1,674 km / h (for example, the speed of a Boeing 777 is 950 km / h). If the Earth suddenly stopped, people would continue to move by inertia.

2. People will not be able to fly into space

Some sci-fi movies claim that if the Earth were to stop, then people would fly into space, subjected to inertia. But since the speed of the Earth in space is 40,000 km / h, the inertia force would not be enough to “fly away” from the planet.

3. A global hurricane will destroy most cities

Given that the Earth's atmosphere moves along with it at an identical speed (1,674 km/h), a sudden stop would lead to the formation of a devastating hurricane over almost the entire planet.

4. A tsunami will pass through the Earth

Newton's first law states that an object in motion will continue to move further unless it is acted upon by an external force. Since all the oceans on Earth are in constant motion, when stopped, the force of inertia will cause a tsunami to rise in the oceans, which will sweep everything 27 km from the coast in less than a minute.

5. Earthquakes will start

The various forces of nature are so perfectly balanced that stopping the rotation of the planet will upset this delicate balance. Earthquakes will start everywhere.

6. Numerous fires will break out

The rapid change in wind speed and rising hurricanes mentioned in paragraph 23 will cause spontaneous fires to start everywhere.

7. GPS will stop working

Global positioning systems (GPS) use satellites whose orbits are carefully calculated. If our planet stops spinning, all calculations will go wrong. But GPS is used in all aircraft.

8. The night sky will become more static

If the Earth stops, most of the stars will "freeze" in their places. In this case, the apparent motion of other planets will not change.

9. The moon will eventually crash into the Earth

The Moon is currently (slowly) moving away from the Earth. If the Earth stops, the Moon will start to slowly approach the planet, eventually crashing into it after millions of years.

10. Day and night will last for six months

If our planet stops its rotation, the sun will illuminate each half of the Earth for half a year. At the same time, the other half of the planet will be immersed in total darkness for half a year, which will lead to the death of plants.

11. The poles will remain almost unscathed

Since the speed of the Earth's rotation is most noticeable at the equator, if the Earth stops, the polar bears and penguins on the pluses will hardly notice the change.

12. Sunlight won't reach the Earth's surface.

Dust and debris that will rise into the atmosphere when the Earth comes to a standstill will likely obscure the sunlight. Also, do not forget about volcanic eruptions, which can begin after the balance of forces of nature is disturbed.

13. The sun will move across the sky in a different way.

If the Earth does not rotate on its axis, the sun will rise in the west and set in the east.

14. The earth will become a sphere

Because of its rotation, the Earth has the shape of a geoid - it is more convex at the equator and flattened at the poles. If the Earth stops spinning, it will become round, and sudden elevation changes of up to 8 km will flood many low-lying regions.

15. Oceans will be redistributed

When gravity gets stronger at the poles, the oceans will concentrate around the North and South Poles, and a single supercontinent will form around the equator.

16. The winds will change completely

Modern winds move parallel to the equator, but when the rotation of the planet stops, they will begin to move from the equator to the poles. This will lead to global climate change.

17. The surface of the oceans will become mist

Hurricane winds will disperse the surface layer of any body of water, including the oceans, creating spray and water suspension above the water, as well as causing waves that will capsize any ships.

18. Marine life will die

The movement of the oceans towards the poles, as well as their churning near the surface, will mean that any oxygen-breathing creatures will not survive.

19. Global temperatures will start to drop

We used to ask such strange questions as, for example, "What would the world look like if all the ice on Earth melted" or for example "What happens if you dig a tunnel through the center of the Earth"

And now the next situation: imagine that the Earth has stopped. It is argued that if the Earth suddenly stops rotating around its axis, life on the planet will become impossible.

Why so let's see...

This is not as simple a question as it seems. The answer depends on what and how it stops. There may be several options - a sudden stop of rotation around the axis, the same thing, but smoothly, and finally - a stop in space, that is, the cessation of movement around the Sun. Due to the insufficiently specific question, we will consider all three options.

An abrupt stop of rotation around the axis is practically impossible - except in the case of a very powerful impact of a large asteroid in the opposite direction, and even then the Earth will not stop at all and not at all so quickly. But ... let's say the Earth abruptly stopped its rotation. What awaits us in this case.

The earth rotates from west to east with a linear velocity at the equator of 465.1013 m/s (1674.365 km/h).

In particular, all objects will "continue" to move, while developing a speed of more than 1,500 km/h. A strong wind will appear, which will instantly lead to a giant tsunami. The day will stretch for a year: first, the Sun will shine without ceasing for six months, and then those who can survive the record heat and drought will plunge into darkness and frost for another half a year. The oceans due to gravity will move to the poles, and the land will be distributed along the equator. And finally, the last survivors will be killed by solar radiation.

You can also remember that the Earth is not at all solid - the earth's crust - everything is the same as the peel of an apple. Beneath this crust is liquid magma and a core that also rotate. With a sudden stop of the Earth, all this liquid substance will still rotate several times, crushing and breaking the “apple peel”. As a result, such powerful earthquakes with many kilometers of faults and volcanic eruptions will instantly occur where they never existed, that hardly anything alive will remain on this planet. In addition, the atmosphere will also "rotate" around the Earth. Moreover, its speed will be the same as the speed of rotation of the Earth, and this is about 500 m / s, then such a wind will blow away everything that is possible. Maybe there will even be a loss of the atmosphere, total or partial, due to the force of inertia.

All this is possible, but, most likely, everything will happen to the point of banality simply - the huge kinetic energy of the Earth and the forces of inertia will tear it apart and the usual bang will happen. And the shreds will fly through the back streets of the solar system.

The online magazine Tech Insider has released a video showing the development of events in the event that the Earth stops abruptly.

In the case of a smooth stop of rotation, everything will happen not so scary. Scientists have already simulated such a situation. There will be a redistribution of land and ocean. Due to the disappearance of centrifugal force, water will no longer tend to the equator. The continents will move there. Both the northern and southern regions will be flooded. Two separate oceans are formed - North and South.

And approximately along the equator, taking into account the tilt of the earth's axis, one continuous continent is formed, encircling the Earth. At the same time, a day on the planet will last exactly a year - until the Earth completes a complete revolution around the Sun. Instead of the seasons of the year, there will be seasons of the day - night, morning, afternoon and evening. Accordingly, the climate will be different - during the day the tropics, and at night - the Arctic. The movement of atmospheric air will soften it somewhat, but not much. After all, practically the polar oceans will not be too warm and will exert their cold influence.

There is another option for stopping the Earth - if it stops moving in orbit around the Sun.

This, of course, is impossible, but no one forbids to imagine ... If the Earth is stopped and left to itself, then the following will happen - the planet will leave its orbit and rush towards the Sun. But it will not reach it, since the Sun also has its own movement in space.

The Earth will fly quite close to it in a cometary orbit. The solar wind will blow away the entire atmosphere, all the water will evaporate. A charred ball flying past the Sun, which was once a "blue planet", will rush further into space. The Earth will reach the orbits of the giant planets, maybe even the orbits of Neptune or Pluto, until it turns back towards the Sun. But this is at best. We must not forget that the Earth is not an ordinary asteroid, but a very massive body. With its movement, it will bring confusion to the movement of other planets and their satellites, which are not very far away. All of them will leave their orbits and their movement is unpredictable. Once between or near giant planets such as Jupiter and Saturn, it can be torn to shreds by them. In this case, another asteroid belt will appear. In addition, on its way the Earth will meet asteroids of different sizes, which can also participate in the "finishing off" of the Earth's corpse.

Such scenarios of events are possible only because of the cessation of the Earth's rotation ... In any case, if we see the Earth after that, we will not recognize it.
