If the sun disappears, will there still be four seasons on Earth?

Now the sun has not disappeared, and many places on the earth do not have four seasons throughout the year, but only rainy and dry seasons. If the sun is gone, I don't know if the earth is there, and there is nothing to do with you.

Well, if the sun disappears, I don't think there will be four seasons, because all the activities on the earth, including the rotation and revolution of the earth, are centered on the sun, and without the sun, I don't think it's even very likely that there will be living things.

There will be no more, and all solar receivers will be scrapped, water supply, power supply will become a big problem, and the plan for a solar flying car or something that will be launched in the future will come to naught, which is undoubtedly a huge blow to human scientific research.

Without the sun, even the white bars will disappear, and the earth will always be in a state of darkness, and naturally there will be no four seasons.

There will be no change of seasons, and the whole earth will be dark.

Without the sun, the earth would be dark and cold, and there would be alternating seasons.

There is already an answer in the ancient Chinese myth "Hou Yi shoots the sun", after Hou Yi shot down nine suns, the tenth hid and did not dare to show his face, so the world was dark, **There are four seasons? Later, the rooster crowed before he dared to come out, and the earth returned to normal. Although it is a "myth", there is some truth to it.

Immediately there was no going on, and it went straight into winter mode.

If the sun disappears, the Earth may not be able to exist properly.

The change of seasons that occurs on the earth is due to the rotation of the earth, which causes the earth to be at a different distance from the sun at different times of the day.

The change of seasons on the earth is due to the angle between the plane where the earth's rotation and rotation orbit are located, causing the earth to rotate obliquely.

The rotation of the earth produces the distinction between day and night, and the rotation of the earth produces the changes of the four seasons of spring, summer, autumn and winter.

The fundamental reason for the change of seasons is that the Earth's axis of rotation is not perpendicular to the plane of its orbit, and the angle of deviation is 23 degrees 26 minutes (yellow-red angle). Depending on the season, the northern and southern hemispheres receive unequal sunlight, with the sunshine being more in summer and the other half in winter.

<> from Copernicus. Proposed heliocentrism.

We all know that the Earth revolves around the star Sun.

The Sun is a non-sporadic burning star. There are four seasons on the earth, which are spring, summer, autumn and winter.

The change of seasons occurs because of the movement of light from the sun on the earth.

By scientists with warp and weft threads.

For the circumcision of the earth, we can know that the horizontal line is the weft line, and the longitudinal line is the meridian line.

The warp starts at zero degrees, and the weft also starts at zero degrees. The zero-degree parallels are called the equator. The earth is divided by the equator into the northern and southern hemispheres.

by zero degree warp.

The corresponding 180-degree meridian divides the eastern and western hemispheres.

As we all know, the Earth is an irregular sphere that produces the alternation of day and night and the seasons with its own rotation and revolution around the Sun.

The change of seasons on the earth is the result of the rays from the sun moving up and down the parallels.

First, the Earth revolves around the Sun at a certain angle of inclination. The first time of the year when the sun's rays appear on the equator is the earth's spring. The sun's rays rotate with the Earth.

There is a movement to the northern hemisphere, and after moving to the northern latitude line, it is summer in the northern hemisphere of the earth, and the time of daylight saving time is three months. Three months later, the direct point of sunlight returns to the equator in the Northern Hemisphere for autumn. After another three months, the direct point of sunlight moves southward under the rotation of the earth.

The direct point of the sun's rays until it moves to the Tropic of Capricorn, which is summer in the Southern Hemisphere. In this way, the earth receives the sun's rays and repeats the cycle of the seasons.

To sum up, this is my basic expression of the change of seasons that occur on the earth. It is also my explanation of why the earth has different seasons.

My explanation may not be comprehensive and specific, but it is my most basic and simple explanation of the alternation of seasons on Earth.

Of course, this explanation is because it is easy for everyone to understand. Obviously, the change of seasons on the earth is not as simple as I have explained, but in principle, it is probably like this.

In fact, the change of seasons on the earth is caused by the rotation of the earth and the revolution around the sun.

The main reason is that the earth's orbit and rotation orbit are different, and then different weather is formed, and it is also the distance from the sun that determines the change of seasons.

Under the circumstance of the earth's revolution, there are some angles between the ants and the orbit, so when it rotates, because the distance from the sun is different, it will be different in the climate.

The earth has four seasons because there is an angle between the earth's orbit around the sun and the axis of the earth's rotation, so when the earth is in different positions on the earth's orbit, the angle of sunlight on the earth will be different, and this difference will reach the maximum when the sun is about and around, and basically in the middle when the sun is about and around. The same place on the earth absorbs different amounts of heat in different locations, resulting in the four seasons that repeat themselves.

The existence of the yellow-red angle is of great astronomical and geographical significance. The yellow-red angle is one of the causes of the precession of the earth's axis, and it is also the main reason for the annual variation of the length of the solar day. The yellow-red angle is the fundamental reason for the change of the four seasons and the distinction of the five zones on the earth.

The yellow-red intersection angle, also known as the ecliptic intersection angle and the yellow-red elongation, is the intersection angle of the earth's orbital plane (ecliptic plane) and the equatorial plane (celestial equatorial plane). The Earth's yellow-red angle is about 23°26'。The yellow-red angle is not constant, it has been changing slightly, but it is negligible for a short time because the change is small.

In the process of the earth's revolution, due to the tilt of the earth, the sunlight regularly shines directly or obliquely on a certain place, so the temperature changes regularly, forming the four seasons.

Because of the tilt of the Earth's rotation, the direct point of the Sun alternates back and forth between the north and south degrees of the equator (Tropic of Capricorn), so the Earth has four seasons.

It's because of the revolution of the earth.

The change of seasons is because the Earth's orbit is at an angle to the plane of the orbit, causing it to rotate sideways. The Earth's orbit is approximately a perfectly circular ellipse, with the Sun roughly at one of the focal points. The Earth's autobiography always maintains a certain angle relative to the Sun, so at different times of the Earth's rotation, the angle of the Earth and the Sun at a certain point is different, which leads to differences in the amount of heat received and the time and length of day and night.

That's the season of the year. In the same way, the tropics only have summer, because the sun's rays always shine directly near the equator. For the same reason, the poles of the earth have polar day and polar night.

Seasonal changes on Earth are due to nuclear changes that occur inside the Sun, while the accumulated and erupted energy radiates to the Earth's surface. For the different energies received by different regions of the earth's surface, the changes in the seasons have been generated. Differences in energy reception lead to differences in the seasons in different regions.

The place where the sun absorbs the most energy, it is called the direct point of the sun, it is the intersection of the center of the earth and heliocentrism, and it is also the hottest place. On the side of the point where direct sunlight hits, the temperature becomes lower and lower until the lowest temperature reaches the extreme.

It is the rotation of the earth that causes the changes in the seasons on the earth. However, once the laws of the Earth's revolution change, the changes in the seasons will naturally have an impact. According to relevant scientists, the reversal of the earth may lead to the reversal of the four seasons in the original normal order of the earth, that is, spring, summer, autumn and winter become winter, autumn, summer and spring, and the earth's revolution is reversed, and the earth's four seasons are reversed.

Of course, this is only a speculation and a hypothesis, and some scholars believe that the return of the earth will not have a great impact on the four seasons, will not change the order of the four seasons, it is still spring, summer, autumn, and winter, because the law of growth is unlikely to change that point, therefore, as long as the earth is arranged in the order of autumn, winter, summer and spring, it will not rule the change of the four seasons. The Earth's "counter-revolution" will also have a huge impact on the Earth's climate. If the Earth were to change its orbit, the natural environment on Earth would be very different from what it is now.

On top of that, if there is a sudden change in the Earth's revolution, there is a high chance that violent volcanic eruptions, tsunamis, and other natural disasters will occur on Earth. The occurrence of this natural disaster is likely to be the most serious crisis for mankind at present. Since the earth's access to solar energy is relatively fixed, the earth's atmosphere, soil, water, and these three things will not change greatly, and there can still be a basic living environment for human beings.

However, due to the reverse rotation of the earth, the overall environment of the earth has changed, which is impossible, and once the direction of the revolution really changes, it is also unknown whether it will bring catastrophic disasters to human beings.

The main reason is that the earth revolves around the sun all the time, and the direct point of the sun is different in each season, so there will be a change of seasons.

How can the earth not turn?!

The rotation of the earth includes both rotation and revolution.

If the Earth's rotation had stopped, then there would have been no day or night – the side facing the sun would always be day, and the side facing away from the sun would always be night! What's more serious is that after the earth stops rotating due to inertia, people and other objects on the ground will be thrown out!

If the rotation of the earth had stopped, then there would have been no change in the seasons! What's more, when the Earth stops orbiting, the Earth will be sucked into the Sun by a huge gravitational pull! (The Earth and other planets are not drawn into the Sun by gravity because this gravitational force is the centripetal force for the Earth and the other planets to revolve around the Sun!) ）

Inertia. By the universe big ** theory: after **, the universe is full"Gas"These gases rotate locally and are brought together by gravity, because angular momentum is conserved, and the formed planet is also rotating.

If there is no interference from other planets, the earth will rotate at a uniform speed, but this is the theory. The specific mechanical effects analysis is complex and can be understood in terms of the overall energy, such as the gravitational pull of the moon to cause tides, which will inevitably undergo energy conversion. Also, the distance between the four seasons and the sun changes, winter is near and summer is far away (yes, you will know if you have studied geography in high school), and so on.
