What are the phenomena produced by the rotation of the earth, and what are the 5 phenomena produced

The Sun also revolves around the center of the Milky Way in the Milky Way, and it takes more than 200 million years to make one revolution. So what happens as the Sun revolves around the center of the Milky Way?

The earth revolvesThe main phenomena are as follows:

1. According to the height of the sun.

The difference is divided into five bands.

Northern cold, northern temperature, tropical, southern temperature, southern cold;

2. According to the time difference of how much heat is obtained, the four seasons are divided: spring, summer, autumn and winter;

3. The change of the length of day and night;

4. Changes in the position of celestial phenomena; the phenomenon of biological growth law;

5. Changes in the height of the sun at noon.

Revolution and rotation.

1. The rotation of the earth is an axis rotation The observation over the North Pole is in a counterclockwise direction, and the observation over the South Pole is in a clockwise direction, which is customarily called a rotation from west to east. The rotation period is one day. Angular velocity of rotation.

for 15 degrees per hour, linear speed.

For example, the equatorial sea level is 464 ms, the altitude increases or decreases by 100 m, and the linear velocity increases or decreases by 26 m; The two poles are zero.

2. In addition to rotating around its axis, the earth also revolves around the sun in a certain orbit The period of revolution is one sidereal year, about 365 days, 6 hours, 9 minutes and 10 seconds. The direction of revolution is also from west to east, and the orbit is an ellipse with an oblateness of 1 60. The perihelion of the orbit is 100 million kilometers, and the aphelion is aphelion.

is 100 million kilometers, the average distance from the sun is 59 minutes per day, the average speed is kilometers per second, and the surface velocity is 14 square kilometers per day. The first two of these have seasonal variations.

Four seasons change, four seasons change, four seasons change, four seasons change.

The earth only rotates because the sun rotates at high speed. The equatorial plane of the solar system space body of the solar system, which is rotated by the gravitational pull of the sun due to the rotation of the sun, does not rotate itself.

The rotation of the earth is due to the fact that the gravity of the earth body has a heavy region and a light region, so that the heavy region presses on the light region and rotates. It's like a ball on an inclined plane rolling down. The difference is that the ball on the inclined plane rolls down and is a condition given by the inclined plane.

The rotation of the earth is the reaction of the sun's light and heat with the water on the surface of the earth and the expansion of the earth into qi and leaving the ground, making the sphere the lightest during the day. At night, the water vapor that expands into gas by the interaction with the sun's light and heat increases the weight of the sphere at night, and the area of the sphere is the heaviest every morning, and the heavy side presses the light side to rotate. It can be seen that the rotation of the earth is not the effect of the gravitational force of the sun, nor is it the effect of inertia, it is not rotation at all, but the movement of energy.
