What is the period of rotation of the earth, and the period of rotation and revolution of the earth

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 and increases or decreases by 3 to 4 thousandths of a second every 10 years.

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.

The cycle of the Earth's rotation.

Broadly speaking, the period of the Earth's rotation is 1 day. The measurement of the Earth's rotation period requires finding a reference point in the extraterrestrial sky that is beyond the Earth's rotation. There are three types of astronomical days in length, which are sidereal days, solar days, and lunar days, with the vernal equinox, the sun, and the moon as reference points, respectively.

What is commonly referred to as a day (day and night) refers to the solar day.

The celestial globe is a reflection of the Earth's rotation. Thus, the period of the Earth's rotation can be determined from the period of the solar movement of the celestial bodies. A sidereal day is a cycle in which the same star is in the same place twice in a row.

In the same way, the solar day is the time it takes for the Sun to be in the same place twice in a row. A lunar day is the time that the Moon experiences twice in a row in the same earth.

Of the above three cycles, only the sidereal day is the true cycle of the Earth's rotation, that is, the time elapsed by the Earth's rotation of 360°, because stars are often regarded as fixed points on the celestial sphere.

The Earth's rotation period is 23 hours, 56 minutes and 4 seconds.

The earth revolves. A week is about a year (days), the orbit of the Earth's revolution is elliptical, the semi-major diameter of the orbit is 149597870 kilometers, the eccentricity of the orbit is 1 km, and the average orbital velocity of the revolution is kilometers per second; The orbital plane of the revolution (ecliptic plane.

The angle to 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 Earth's rotation period is one day (23:56:4 seconds), and the Earth's rotation has a day and night cycle.

According to the sidereal year, the Earth's orbital period is: days, or 365 days, 6 hours, 9 minutes, and 10 seconds.

According to the return year, the Earth's orbital period is: days, or 365 days, 5 hours, 48 minutes and 46 seconds.

According to sidereal days, the Earth's rotation period is: 23 hours, 56 minutes and 4 seconds.

The Earth's rotation period is 24 hours.

The Earth's rotation period is generally written as one day (the exact time is 23:56:4 seconds), and the Earth's orbital period is generally written as one year (the exact time is in days).

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.

The rotation period of the Earth is 23 hours, 56 minutes and 4 seconds.

A rotational astronomical noun that refers to the time it takes for a celestial body to rotate around its axis of rotation. Typically, the rotation period is equal to the length of the sidereal day of that celestial body. 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 day-night cycle is a dynamic concept, mainly generated by the movement of the earth's rotation, because the light source comes from the sun, so the cycle of day-night cycle is a solar day, that is, 24 hours. The Earth's rotation period is 23 hours, 56 minutes, and 4 seconds, also known as a sidereal day, rather than 24 hours, because the Earth's rotation is also revolutionary, which causes the relative position of the Sun to the ground to change.

Introduction to Earth

The Earth's atmosphere is mainly made up of nitrogen and oxygen. The tropics receive more solar energy than the polar regions and redistribute it through atmospheric and oceanic circulation. Greenhouse gases also play an important role in regulating the surface temperature.

The climate of a region is determined not only by latitude but also by factors such as altitude and proximity to the region and the ocean. Severe weather such as tropical cyclones, thunderstorms, and heat waves often occur in a wide area and have a great impact on life.

The Earth's gravitational pull interacts with other objects in space, especially the Moon, which is the Earth's only natural satellite. It takes about a few days for the Earth to revolve around the Sun. The Earth's axis of rotation is tilted relative to its orbital plane, thus producing seasons on Earth.

The gravitational interaction between the Earth and the Moon causes tides that stabilize the direction of the Earth on its axis and gradually slow down its rotation.
