The earth has a fixed momentum moment at the time of the birth of BAI, and the gravitational pull of the sun during the movement of the earth is parallel to this momentum moment, and the DAO has an inherent periodic rotation due to the conservation of momentum moment.
But it has been proven that the Earth's rotation period is not only increasing, but very slow. This is mainly due to the effect of the gravitational pull of the moon, because there are three-quarters of the oceans on the earth, under the action of the gravitational force of the moon there are periodic tides, this large-scale movement of water bodies and the earth produce a certain friction, and the friction is perpendicular to the earth's self-sealing of the phoenix wet splashing moment of rotation, so it will change its angular velocity, making it slower and slower. Because the earth rotates in one day, and the moon rotates in one month, as long as their cycles are different, there will always be tidal phenomena.
The Earth's rotation period will continue to increase until the Earth's rotation period reaches one month, when the Moon will be stationary relative to the Earth, and will reach a stable state thereafter. Therefore, the final day on Earth will be a month now.

The law of the Earth's rotation is from east to west. Counterclockwise over the North Pole and clockwise over the South Pole. The rotation of the earth will cause the phenomenon of day and night, which will cause various motion rotation phenomena, and the earth will produce different latitudes and longitudes, and the time will vary by an hour every 15 degrees of longitude.
-
The law of the Earth's rotation is that the linear speed of the Earth's rotation decreases from the equator to the poles, and the Earth's rotation is one day.
The natural phenomena that do not occur when the earth's rotation is as follows: day and night, the hemisphere facing the sun is day, and the hemisphere facing the sun is night; time difference between the East and West regions; Where there are different places at different degrees of longitude, the longitude varies by one hour every 15 degrees.

The rotation of the earth is from west to east. The natural phenomenon is the alternation of day and night, and there is also a time difference, and there is also a geostrophic deflection.

The centrifugal force of the revolution is balanced with the gravitational force of the sun, so that the earth will not fall on the sun and burn up. Due to the effect of the sun's gravitational field and rotation, the rotation of the earth also has its own laws.
This is related to the formation of celestial bodies. The Earth rotates from west to east on its axis of rotation, rotating counterclockwise from the North Pole and clockwise from the South Pole. The Earth's axis of rotation is angled to the ecliptic plane, perpendicular to the equatorial plane.
Extended Materials. The Earth rotates from west to east around its axis of rotation with an average angular velocity of 15 degrees per hour. At the Earth's equator, the linear velocity of rotation is 465 meters per second.
The phenomenon of various celestial bodies rising in the sky rising in the east and setting in the west is a reflection of the rotation of the earth. The cyclical changes of the Earth's rotation mainly include changes in annual cycles, changes in monthly cycles, semi-monthly cycles, and changes in near-Sunday and semi-Sunday cycles.
The orbit of the Earth is elliptical, the semi-long diameter of the orbit is 149597870 km, the eccentricity of the orbit is 1 km, and the average orbital velocity of the revolution is km per second; The angle between the orbital plane (ecliptic plane) and the Earth's equatorial plane is 23°27', known as the yellow-red cross. The rotation of the earth produces the diurnal variation of the earth, and the rotation of the earth and the existence of the yellow and red angles cause the alternation of the seasons.

The phenomena produced by the rotation of the earth are:1. The difference between day and night and time in the northern and southern hemispheres.
2. The earth rotates from west to east, and the time of one rotation is 24 hours.
3. Time difference means that when the earth's rotation occurs in the place, the time in the east is earlier than the time in the west, and the local time difference is one hour every 15 degrees of longitude.
4. The direction of the horizontal motion of the object is biased. It is biased to the right in the northern hemisphere and to the left in the southern hemisphere.
5. Influence on the shape of the earth. The inertial centrifugal force generated by the rotation of the earth causes the earth to gradually expand from two stages to the equator, becoming a slightly flattened spheroid.
6. The sun, moon and stars rise in the east and set in the west.
The law of rotation. The movement of the Earth's axis on the ground is called pole shift.
There are two main reasons for pole shift, one is the result of the deviation of the earth's axis from the axis of inertia, with a period of about 14 months; The other is caused by the seasonal operation of the atmosphere, which has a period of one year. There are other secondary reasons, the amplitude of the pole shift is generally not more than 15 meters, and the result of the pole shift is a change in latitude and longitude on Earth.
To put it simply, the rotation and the revolution are all about getting rid of the attraction of the sun to the earth, and that's it.
The rotation of the Earth. A week is a day, or a day.
The Earth's rotation period has sidereal days and solar days. >>>More
No, the vernal equinox day refers to the day around March 21, and the vernal equinox day is the division of solar terms in China, which is divided into 24 solar terms. The date of the autumnal equinox is around September 23. The day of the vernal equinox belongs to spring in the Northern Hemisphere and autumn in the Southern Hemisphere. >>>More

You are so smart, tell you about it and you will understand: the earth starts to rotate 360 degrees from the time you are facing the sun, and at the same time revolves about 1 degree around the sun, you are no longer facing the sun, 23 hours, 56 minutes and 4 seconds is the time for the earth to rotate 360 degrees in the strict sense, in fact, you rotate a little more than 360 from this noon to the next noon. >>>More
