What would happen if the Earth's rotation suddenly stopped?
Do you feel that time is getting slower and slower, don't say that the editor is alarmist, because it is a fact. Everyone knows that there are 24 hours in a day now, but in the Jurassic period, there were only 23 hours a day, and 13 years ago, the earth's day was only 18 hours.

In addition to the longer time, the moon is also moving away from us day by day. After observation and calculation, astronomers found that the moon is moving away from the earth at a rate of 4 centimeters per year. If hundreds of millions of years pass, future humans may see the moon as we see it now Like the stars.
In fact, all of this is inseparable from the tidal phenomenon brought by the moon to the earth. First of all, let’s understand what the tidal phenomenon is. In layman’s terms, the tidal phenomenon is due to the position changes between the moon, the sun and the earth. Gravity will change accordingly.
The oceans on Earth will be affected by this, and the oceans will move violently under the influence of tides. And it is fixed twice a day, which is what we often call the ebb and flow of the tide. France also gave this phenomenon a romantic name, "breathing of the sea".

The ocean, which is affected by tidal phenomena, consumes the energy of the earth's rotation all the time. If the energy decreases, the earth's rotation speed will definitely slow down.
According to research by scientists, the earth will increase by 1.7 milliseconds every day. What is the concept of 1.7 milliseconds? One second is equal to ten seconds, one minute and second is equal to ten centiseconds, and one centisecond is equal to ten milliseconds. Not as much as we blink once, but under the influence of time?
According to the research data of scientists, the time of the earth will increase by 1.7 milliseconds every day. If things go on like this, the day in the future will become longer and longer. This has a lot to do with the rotation speed of the earth. In addition to the influence of the lunar tide phenomenon, There is another very important reason.

When the earth is traveling in the universe, space dust and meteorites of all sizes in the universe will also come to the earth under the influence of gravity. Scientists have speculated that the earth will attract about 40,000 tons of matter every year. Invisibly affects the rotation speed of the earth.
So if one day in the future, the earth suddenly stops spinning, what will happen?
To know what will happen, we need to understand the rotation speed of the earth, which is about 465 meters per second.

Fold in half, and the earth stops suddenly at a rotation speed of 200 meters per second. At that time, all objects on the earth's land will fly out at a speed of 200 meters per second under the influence of inertia.
Just like a large truck that is traveling at a speed of 60 kilometers per hour and suddenly brakes suddenly, the goods on the vehicle will fly forward quickly due to inertia.
Back to the topic, not only objects on land are affected by inertia, but seawater in the ocean will also move at this speed, and finally form the strongest tsunami in history. The huge tsunami will wash away all objects in coastal cities, even if they are 100 meters away. Tall buildings, then the coastal areas would be bare.

The next thing to be affected is the atmosphere. Some people said, what big waves can be caused by the gas, but you are wrong, the power of the air is much stronger than you imagined.
The atmosphere will also move along with the rotation of the earth. If the rotation stops suddenly, the atmosphere will move forward at a very high speed due to inertia, and there will be strong winds with a speed of more than 1,600 kilometers per hour on the earth. You know, so far, the earth The maximum wind is only 407 kilometers per hour.
Under the raging wind, the houses on the earth are blown away, and everyone on the ground will be taken up to a high altitude, and then fall down hard, even if you are a 200-jin fat man.

Part of the atmosphere may also break away from the earth, the atmosphere will become thinner, and the radiation in space will become stronger. Life on the earth will be devastated. One hour after the earth stops rotating, all volcanoes will be destroyed by underground magma. The shaking erupted.
The erupted volcanic ash entered the remaining atmosphere, blocked the sunlight, and the surface temperature dropped sharply. After a long time, the earth will enter the next ice age.

Volcanic ash will fall to the surface sooner or later. At that time, the entire earth will be buried hundreds of meters deep in the volcanic ash. At the same time, the side facing the sun will welcome the long-lost sunlight. It will be higher, and half of the earth will be shrouded in high temperature.
The situation on the side facing away from the sun is also not good. Due to the long-term absence of sunlight, the temperature has become extremely low. This half of the earth is still covered with ice and snow, and the other side is like two worlds.

Even if human beings are not extinct due to the strong inertia at the end of rotation, this high temperature and low temperature environment is not suitable for human survival. Human beings may be completely extinct, or they may evolve again.
Of course, this is just an assumption. Although the rotation speed of the earth is slowing down, we will not see it stop in our lifetime.
