What would happen if our planet suddenly stopped? In fact, this question is much more complex than it might seem at first glance, since the answer to this question largely depends on how and in relation to what it stops. And there can be several options - stopping in space, or stopping rotation around an axis, or the same thing, but smoothly. Let's look at all three options.
An abrupt stop of rotation around an axis is practically impossible - unless in the case of very powerful blow 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 suddenly stops its rotation. What awaits us in this case. 
First, let's remember that the Earth is not solid at all - Earth's crust- everything is the same as the peel of an apple. Beneath this crust is liquid magma and a core that also rotates. When the Earth suddenly stops, all this liquid substance will still turn several times, crushing and breaking the “apple peel”. As a result, such things will instantly happen powerful earthquakes with many kilometers of faults and volcanic eruptions where they never existed, it is unlikely that anything alive will remain on this planet. In addition, the atmosphere will also “turn” 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. There may even be a loss of atmosphere, complete or partial, due to the force of inertia.
All this is possible, but, most likely, everything will happen to the point of banality - a huge kinetic energy The earth and the forces of inertia will tear it apart and the usual bang-bang will happen. And the shreds will fly through the back streets of the solar system.
If the rotation stops smoothly, everything will not be so bad. Scientists have already modeled this 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. Continents will most likely move there. Will find themselves flooded northern regions, and southern ones. Two separate oceans are formed - Northern and Southern. 
And approximately along the equator, taking into account the inclination earth's axis, one continuous continent is formed, encircling the Earth. In this case, a day on the planet will last exactly a year - until the Earth completes full turn around the Sun. Instead of seasons of the year there will be seasons of the day - night, morning, day and evening. Accordingly, the climate will be different - tropical during the day and arctic at night. Movement atmospheric air It will soften it somewhat, but not much. After all, practically polar oceans will not be too warm and will have 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 you to imagine... If the Earth is stopped and left to its own devices, then the following will happen - the planet will come down from orbit and rushes 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 again towards the Sun. But this is in best case scenario. We must not forget that the Earth is not an ordinary asteroid, but a very massive body. With its movement it will cause confusion in the movement of other planets and their satellites, which are not very far away. They will all leave their orbits and their movement is unpredictable. Finding itself 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, the Earth will encounter asteroids on its way different sizes who will also be able to take part in “finishing off” the corpse of the Earth.
Such scenarios of events are only possible due to the cessation of the Earth’s rotation... In any case, even if we see the Earth after this, we will not recognize it.
What will happen to the world if the earth suddenly stops rotating on its axis.
We know very 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 its complete stop will occur 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 caused by processes that occurred during the time of its formation. In those days the clouds cosmic dust huddled together in one “heap”, to which others were attracted cosmic bodies. As a result of this confusion, the planet was formed over billions of years. And its rotation is due to the inertia that remained after the collision with the same cosmic
Why is the Earth slowing down?
At the dawn of its existence, our planet rotated much faster. A day then was about 6 hours long. It has become a popular opinion that the Moon influences the change in the speed of rotation of the Earth most of all. With its force of attraction it causes fluctuations in the water level in earth's oceans. Due to 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 incredible, but why not? Today, the Earth's rotation speed is no less than 1670 km/h. If the planet suddenly stops, everything that was on its surface, including people, will be instantly swept away due to the action of centrifugal force. In fact, the Earth will stop, but objects on its surface will continue to move. This option may be more acceptable to people, because everything will happen so quickly that no one will understand anything. But in the case of a gradual deceleration of the Earth, we will have to experience many destructive 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 this could happen earlier. Scientists do not rule out that the planet’s rotation speed may decrease, for example, due to a collision with an asteroid. Such an event in itself will be disastrous for earthlings, and a slowdown in the planet’s rotation speed will be an unpleasant bonus to everything. But let's imagine that this happened without the participation of huge asteroids, but for more “inconspicuous 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 minor changes compared to other global changes, ranging from terrible cataclysms to the redistribution of the waters of the World Ocean, which will lead to mass death of all life on the planet.
The concept of a day will disappear. On one side of the Earth there will be eternal day. At the same time, the constant sun will destroy many plants, and the soil will dry out and crack. Dark side The earth will be like a snowy tundra. Scientists believe that the intermediate region between day and night will be more or less suitable.
Equator without oceans
The waters of the World Ocean will change their location, moving from the equator to the poles. That is, 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 no longer be evenly held and will actually “flow down” from the equator.
Climate and planetary habitability
In addition to the fact that the land and oceans on Earth will look different, the climate will also change dramatically. Now the winds blow parallel to the equator, but if what happens, they will blow from the equator towards the poles. The currents will naturally change. Which climatic conditions will be in one region or another, it is difficult to say, but you can be sure that one hemisphere will be dry and the other incredibly cold. The Earth's atmosphere is like ocean waters, closer to the poles it will become denser, and at the equator it will thin out. Due to the fact that the metal core of the Earth rotates, there is a magnetic field around it. It provides protection from harmful 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 straight lines sun rays. Mass extinction among 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.
Will people be able to survive?
People would definitely be able to adapt to new conditions. There won’t be many places left where you can somehow 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 sunrise or sunset depending on the hemispheres. In addition, it will not be possible to settle along the entire “favorable line”, since a considerable part of the land will be flooded by the oceans, and you will have to choose an area where there will be optimal Atmosphere pressure and temperature.
It is possible that due to the 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 common 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 of our planet, hundreds of millions of light years away, not a single place with ideal conditions for humans has been discovered.

People have always been interested in the question of what will happen to the planet and its inhabitants if any disaster occurs. This is probably why Hollywood makes so many movies about the end of the world. There are too many Apocalypse scenarios to describe all the consequences, so we decided to find out what to expect if the Earth suddenly stops (and it really does slow down, by the way). This is what the end of the world will look like in this case.
1. All objects will fly east at high speed by inertia
"We don't notice enormous speed rotation of the Earth. But if it suddenly stopped, says NASA's Sten Odenwald, every object on the planet would break off the surface and fly east at high speeds before falling back down. At the equator, the speed will be the highest (about 1600 km/h), and closer to the poles it will reach 1300 km/h."
2. Huge tidal waves will begin to form
The force of the impulse will cause the water in the seas and oceans to move, which will lead to powerful tsunami, which will go east, washing away coastal cities from the face of the Earth.
3. Wind strength will increase
As the atmosphere continues to move, its rotation speed around the planet will increase several times. The starting speed of the air flow will be enormous: about 1800 km/h. It is possible that the Earth will lose part of its atmosphere as a result.
4. All the water on the planet will be collected in two oceans, which will lead to the formation of a new continent
Currently, water collects at the equator due to the centrifugal force of the Earth. But its sudden stop will lead to a redistribution of land and water, forming two giant oceans at both poles. Land at the equator will form new continent, covering the entire planet. 
5. Volcanic eruptions, hurricanes and earthquakes will begin
The enormous kinetic force of the Earth and its momentum can even affect the core. The result is quite predictable: powerful hurricanes, volcanic eruptions and destructive earthquakes. And this is all over the planet.
6. The Earth will change from a geoid to a sphere
The earth has its geoid shape due to the nature of its movement. Now it is slightly flattened at the poles and expanded at the equator. But if the planet stops, its shape will become spherical.
7. In one hemisphere it will become hot, like in the desert, and in the other, cold, like in Antarctica
If the Earth continues to make only one revolution around the Sun, only half of it will heat up. This means that the temperature here will become too high, especially at the equator. The second hemisphere will turn into a kingdom of eternal night and arctic cold. NASA has another version: The Earth may stop rotating as a whole, and not just around its axis, which will lead to alternating 6 months of heat and 6 months of cold.
8. The magnetic field that protects the Earth from dangerous cosmic radiation will disappear
The magnetic field is formed mainly due to the outer core (which consists of iron) and the movement of the planet around its axis. But if the Earth stops moving, the magnetic field will also disappear, as Sten Odenwald predicts. The field protects us from the solar wind - these are charged particles from the Sun, fatal to any living creature.
9. If people can survive, then only on the border of heat and cold
Humanity will be able to adapt to new conditions only at the border of day and night. People will have to live underground and come to the surface only in protective suits due to radiation.
10. The moon will eventually fall to Earth, but it won't be anytime soon.
Professor Vaughan Pratt of Stanford University says the Moon will gradually slow down and its distance from Earth decrease. Over time, it will probably just fall onto our planet.
In fact, the Earth is actually slowing down. In her youth, she rotated much faster: the day lasted only 6 hours. The Moon's gravity causes ebbs and flows, which gradually reduce the planet's rotation speed. NASA calculated that every 100 years, the length of the day increases by 2.3 milliseconds. Most likely, after billions of years, the days will become so long that the Earth will stop rotating completely.
That the Earth is constantly spinning around own axis Why the change of day and night occurs is known today, perhaps even junior schoolchildren. But physicists talked about what would happen if our planet stopped rotating. In our review, the most incredibly catastrophic scenarios for the development of events
1. People will feel like they're on a roller coaster.
The Earth's rotation speed 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 won't be able to fly into space.
Some science fiction films claim that if the Earth stopped moving, people would fly into space, subject to inertia. But since the Earth's speed in space is 40,000 km/h, the inertial force would not be enough to “fly away” from the planet.
3. A global hurricane will destroy most cities
Considering that the Earth's atmosphere moves along with it at an identical speed (1,674 km/h), an abrupt stop would lead to the formation of a destructive 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 unless it is acted upon. external force. Since all the oceans on Earth are in constant movement, when stopped, the force of inertia will lead to a tsunami rising in the oceans, which will sweep away everything 27 km from the coast in less than a minute.
5. Earthquakes will begin
The various forces of nature are so perfectly balanced that stopping the rotation of the planet will upset this delicate balance. Earthquakes will begin everywhere.
6. Numerous fires will occur
Quick change The wind speeds and rising hurricanes mentioned in paragraph 23 will lead to spontaneous fires starting everywhere.
7. GPS will stop working
Global positioning systems (GPS) use satellites whose orbits are carefully calculated. If our planet stops rotating, all calculations will go wrong. But GPS is used in all airplanes.
8. The night sky will become more static
If the Earth stops, most of the stars will “froze” in their places. At the same time, 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 moving, the Moon will slowly approach the planet and eventually crash 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 six months. At the same time, the other half of the planet will be plunged into pitch darkness for six months, which will lead to the death of plants.
11. The poles will remain almost undamaged
Since the speed of the Earth's rotation is most noticeable at the equator, if the Earth stops, polar bears and penguins on the plus side will notice little change.
12. Sunlight will not reach the surface of the Earth
The dust and debris that will rise into the atmosphere when the Earth stops will likely darken sunlight. Also, one should not forget about volcanic eruptions, which can begin after the balance of natural forces is disrupted.
13. The sun will move differently across the sky
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
Due to its rotation, the Earth has a geoid shape - it is more convex at the equator and flattened at the poles. If the Earth stops rotating, it will become round, and sudden changes in altitude of up to 8 km will lead to flooding of many low-lying regions.
15. Oceans will be redistributed
When gravity becomes stronger at the poles, the oceans will concentrate around the North and South Pole, and a single supercontinent is formed in the equator region.
16. The winds will change completely
Modern winds move parallel to the equator, but when the planet's rotation 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 dusty water
Hurricane-force winds will spray the surface layer of any body of water, including oceans, creating splashes and a suspension of water above the water, and also cause waves that will capsize any ships.
18. Marine life will die
The movement of the oceans towards the poles, as well as their churning at the surface, will lead to the fact that any oxygen-breathing creatures will not survive.
19. Global temperatures will begin to fall
