The rotation of the Earth. A week is a day, or a day.
The Earth's rotation period has sidereal days and solar days.
Points. In sidereal days, it takes 23 hours, 56 minutes and 4 seconds for the Earth to rotate once; In solar days, the time of one rotation of the Earth is 24 hours.
The sidereal day is the true rotation period of the Earth. The sidereal day is 3 minutes and 56 seconds shorter than the solar day.

The time it takes for the Earth to rotate around is 23 hours, 56 minutes and 4 seconds, which is about 24 hours a day. The Earth's rotation is an important form of motion of the Earth, with an average angular velocity of rotation in degrees and a linear velocity of 465 meters and seconds at the Earth's equator.

That's twenty-four hours a day.

It takes 23 hours and 56 minutes for the Earth to rotate around and increases or decreases by 3 to 4 thousandths of a second every 10 years. 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. Various theories about the rotation of the Earth are still hypotheses. The Earth's rotation is an important form of motion of the Earth, with an average angular velocity of rotation in degrees and a linear velocity of 465 meters and seconds at the Earth's equator.

The Earth's rotation period is one day longer than its orbital period. Rotation period, an astronomical term, astronomyally refers to the time it takes for a celestial body to rotate once along its axis of rotation. For example, the dichotox, the alternation of day and night, and the length of day and night are all natural phenomena inherent in the earth, and although they all involve diurnal conditions, their causes are different.
The dichotomy is a stationary concept that does not involve the movement of the Earth, but is determined by the Earth's characteristic that it is an opaque sphere.
Orbital revolution refers to the circular motion of an object along a certain orbit centered on another object; The orbit can be circle, ellipse, hyperbola, or parabolic. In astronomy, it is generally used to describe planets, comets and other stars orbiting stars; satellites, artificial satellites, etc. orbiting planets; Small-scale galaxies, nebulae, cosmic dust, etc., orbit large-scale galaxies; and larger-scale intercelestial orbital motions.

23 hours, 56 minutes, 4 seconds. 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.
Various theories about the rotation of the Earth are still hypotheses.
The Earth's rotation is an important form of motion of the Earth, with an average angular velocity of rotation in degrees and a linear velocity of 465 meters and seconds at the Earth's equator. It takes 23 hours and 56 minutes for the earth to rotate around the earth, and the rotation period increases or decreases by 3 thousandths to 4 thousandths of a second every 10 years, so it is estimated that 400 million years ago, the earth rotated in only 22 hours.
The role and significance of the rotation of the earth:
1. Alternate day and night.
The earth is opaque, and the sun can only shine half of the earth at any one time, making the difference between day and night on the surface. If the Earth only rotates and does not rotate, then the cycle of day and night will not be one day but one year. In this case, everything that is associated with the heat balance on the surface will change radically differently from what it is now.
2. Deflection occurs in the direction of horizontally moving objects.
Coriolis first discovered the deflection force of a moving object in the case of the Earth's rotation, hence the name Coriolis force.
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
No, the Earth's rotation is slowing down.
Even if the Earth's rotation speed does not change, this is not true due to the precession of the Sun's perigee and the existence of the yellow-red angle. >>>More
The circumference is 410,000 kilometers and the rotation time is 24 hours. >>>More
The Earth rotates from west to east around its axis of rotation. Earth's rotation is an important form of motion of the Earth, with an average angular velocity of rotation of radian seconds and a linear velocity of rotation at the Earth's equator of 465 meter seconds. >>>More
It is to generate a geostrophic deflection force, with the northern hemisphere shifting to the right and the southern hemisphere shifting to the left. In addition, the geostrophic deflection force is not a force, but has the effect of changing direction.
