We know that almost all celestial bodies in the solar system, including asteroids, rotate according to the law of the right-hand rule, and the rotation of all or most celestial bodies is also the right-hand rule. Why? The predecessor of the solar system was a dense cloud, driven by a certain force that attracted each other, and this accretion process made the density gradually larger, which accelerated the accretion process.
On the one hand, the centripetal accretion accumulation becomes the sun, and on the other hand, the gas gradually develops into a flattened shape, and in the process of development, the potential energy becomes kinetic energy, and finally the whole thing turns. At the beginning of the rotation, there are those who turn this way, and those who turn that way, after a certain direction prevails, they all become one direction, and this direction is the right-hand rule that is now discovered, and there may be other solar systems that are left-handed rules, but in our solar system it is the right-hand rule. The energy of the earth's rotation** is caused by the eventual transformation of material potential energy into kinetic energy, which ultimately means that the earth rotates on the one hand and rotates on the other.
The rotation of the Earth does not stop, although there is acceleration, it will get smaller and smaller, and it will not reduce the angular momentum to 0.
If only the Earth-Moon system is considered, the deceleration limit is the synchronous rotation of the Earth-Moon due to the conservation of angular momentum, as in Pluto. This is the reason why the moon always has only one side facing the earth, but because the moon is small, the earth is large, and the moon's tidal effect on the earth is small, so the earth is not relatively stationary now, but one day it will still be, and then there will be no tidal action between the earth and the moon. But don't forget that there is relatively no rotation between the Earth and the Moon, but there is still a rotation relative to the Sun, so the Earth's rotation will not stop.
Some of my previous explanations were wrong.
-
Interaction of forces.
Give a reason it doesn't turn.
-
The driving force of the earth's rotation lies in itself, inside the earth and not outside, and in the internal force it has rather than an external force. However, what is the cause of the Earth's rotation? The power of rotation is obtained from **?
Why did you choose the current direction, attitude, and velocity rotation? These are all problems that modern science has not solved so far.
-
It must be because the Earth is in the solar system, because most of the planets in the solar system rotate.
-
Ask God, for he made it.
-
Why does the Earth rotate?
-
The interior of the earth is liquid, and it rotates due to the imbalance of the internal density due to the influence of the earth's revolution!

Introduction: People often say that the earth is of great significance to human beings, and without the earth, human beings would basically not be born. The earth is constantly rotating and revolving, many people do not understand the meaning of the earth's rotation, and make assumptions that if the earth no longer rotates, what will change, let's understand it together.
What would happen if the Earth stopped rotating<>
At present, through research, it is known that the rotation speed of the earth is actually gradually slowing down, although we set a day for 24 hours, but in fact, the time of the earth's rotation for a day does not reach 24 hours, only 23 hours, 56 minutes and 4 seconds, but now it is found that the rotation speed of the earth is slowing down, and the rotation of the earth will take longer in the future, and eventually the rotation of the earth will stop, but this time is quite long, and human beings will not live that day.
What are the effects of the Earth's cessation of revolution on human beings?
If the earth stops rotating, if it stops suddenly, it will be a terrible thing for the life on the earth, all life will be extinct, and the earth may eventually cease to exist.
The Earth's equatorial dimension is relatively low, while the North and South Pole dimensions are very high, and the circumference of the Earth's equator is also the longest, with a speed of 1,600 kilometers per hour on the Earth's equator, and a slightly lower point at the North and South Poles reaching 1,300 kilometers per hour.
This speed is no joke, people must have been thrown out directly, although it will not be so exaggerated as it is to rush out of the atmosphere, but after falling, it is basically impossible to survive unless there is a parachute on the body, but at this time the earth is no longer rotating, even if people do not die immediately, but they are not long from death.
The earth's atmosphere also follows the earth's rotation, if the earth stops rotating, then the atmosphere is still rotating, which will produce a lot of powerful cyclones, itself all kinds of objects are flying in the sky, coupled with strong winds, and eventually the direct danger will increase dramatically.
In addition, if the rotation of the sun stops, the normal day and night will start to be abnormal, and it may take half a year during the day and half a year at night. It was even directly locked onMoonIn the same way, the direct half of the earth is always daytime and the other half is always night.
If the earth no longer rotates, it will be as terrible as the earth stops rotating, and it will be a catastrophe for human beings and all creatures on earth.
-
If the earth does not rotate, then it will cause the back of the earth to always be night, and the front side will always be day, although it will have an impact on the evolution of life, but life will still appear, because life on the earth is not afraid of eternal night, that is, it does not evolve eyes.

No. Because the earth's autobiography can continuously transmit thermal energy from the earth's interior to the surface, so that the earth's temperature can be maintained at a level suitable for life reproduction, providing energy for the birth of life, without the earth's autobiography, life may not appear.
-
No. If the earth does not rotate, then the earth's environment will not be as colorful as it is now, so there will be no life.
Of course, it's like an iron ball, because the blue part is gone, only the black earth remains, and the land area is only 30, which is pitiful.
The ocean covers 71 of the Earth's surface, and if all the water in the ocean were evenly spread on the Earth's surface, a 2,700-meter-thick hydrosphere would form on the Earth's surface. So some people say that the name of the earth is wrong, and it should be called "water ball". From the origin of life on earth to the formation of human society, from a primitive society with low productivity to a modern society with advanced science and technology, man and water have formed an indissoluble bond. >>>More
