Why does the earth rotate Help me

The reasons for this are complex ......Meteorite impacts account for part of ......But you don't need power to turn it.

The last one doesn't seem to be valid.

Depending on what the reference object you are looking at, if the reference object is a person on the ground, the earth does not rotate, but all the objects are always moving, absolutely not stationary, so no matter what is moving, rotation is one of the reasons.

The rotation of the earth due to the action of the sun's gravitational field and rotation also has its own laws. Since**

This has to do with 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.

1. Revolution of the earth.

The rotation of the earth follows the laws of the earth's orbit, the earth's orbital plane, the yellow-red angle, the period of the earth's revolution, the speed of the earth's revolution and the effect of the earth's revolution. The time it takes for the earth to revolve is one year. There are two distinct cycles in the process of the Earth's revolution, which are the return year and the sidereal year, and the time of the return year is not the same as the sidereal year.

The one-year time difference between the two is called precession.

2. The rotation of the Earth.

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 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. Male**

The reason why the earth rotates once in 24 hours is that it orbits the sun at a speed of more than 100,000 kilometers per hour, and encounters the lateral thrust of the solar wind on the way, which causes a plasma westerly circulation in the upper air, which in turn pushes the westerly winds on the ground and the ocean currents that swell eastward, and then pushes the earth to rotate from west to east.
