    How the night is formed Our earth is also a large atom, and the energy emitted by the contact surface of the active plate of the earth's crust and mantle is pushed by three different movements, and the heat energy emitted is also very different. On the one hand, when the energy accumulation is the strongest, it can also make the hard rocks on the contact surface of the earth's crust and mantle be transformed into lava that ejects volcanoes and other materials, and on the other hand, the photon energy emitted by friction and heat synthesis is preserved in the depths of the earth's crust to the maximum extent and can only escape from the active cracks or cavities. Ground light and aurora are generated, and when they are normally reflected and synthesized by the sun's ultraviolet reflector, those photons form the daytime and the hottest time is not at noon, but at 3 to 5 p.m. in the strong force surface field. When the small active plates on the crust move on the gravitational surface field, this field is moving upwards and has a tensile force, which makes it greatly reduce the internal temperature of the mantle when it decelerates, and only electrons can be produced after the evolution of frictional heating, which gradually loses the light, forming the coldest time of night and gradually decreasing temperature.

    And in the uneven rotation of the earth's inclined pole around the self-congregation, it also produces great changes in the cold and hot climate in spring, summer, autumn and winter.

    The reason why there is a difference between day and night on the earth is due to the rotation of the earth, which is a large ball that does not emit light on its own. For the Earth, the sun is stationary.

    The earth is constantly rotating from west to east, one revolution a day, so the earth is always half facing the sun and half facing away from the sun. When you receive sunlight towards half of the sun, it is day, and when you have half of the sun behind you, it is night.

    When the earth rotates in a circle, there is a change of day and night, and the earth is always constantly rotating, and day and night are always changing constantly and regularly.

    The night of the earth is because the sun is constantly revolving, and the earth rotates around the sun, so only half of the place will face away from the sun, and the side facing the sun is the night, which can explain why there is night on the earth, the earth's revolution and rotation are very regular, because the day and night of the four seasons of the year will become different in length with the change of seasons.

    The earth itself has revolution and rotation, the revolution is formed by the four seasons, and the rotation is formed by night and day.

    When you are on the side facing away from the sun, night is formed because the sun's rays cannot be directly hit (scattered).

    Turn your back to the sun and the world is the night! The Earth's alternation of day and night is due to rotation.

    At that time, I was young and didn't know what the road ahead was, so I was full of enthusiasm and hope for the future, and time passed like a white horse, and in a blink of an eye, I had entered the soul and gradually adapted to such a life. But the previous dreams gradually deviated from my track, and I felt that the years were like knives, smoothing our edges and corners. In the vast sea of people, he is neither humble nor arrogant, he moves forward cautiously, and he no longer dares to calm down his frustration attitude.

    <>On earth, there will be alternating day and night in a day, this is not man-made, people do not have such great ability. The cause of this phenomenon is the rotation of the earth.

    The sun is the center of the solar system, and the earth revolves around the sun, and the places where the earth is illuminated by the sun will become very bright, and the places that cannot be illuminated will become very dark.

    We know that the side that is trapped by Taiyou is daytime, and the side that is not illuminated is night. The rotation and rotation of the earth generally rotate regularly, so why do the days and nights of the year vary in length with the seasons?

    That's another question. Since the Earth's axis of rotation is tilted to the ecliptic plane, the length of day and night at a location changes as the Earth rotates. There is a regular pattern in the occurrence of seasonal changes.

    In the summer, the days will be longer, and in the winter, the daylight hours will be shorter. There are even more amazing phenomena in the universe, waiting for people to find out their secrets.

    Day and night are a combination of day and night. The alternation of day and night is a natural phenomenon formed by the rotation of the earth under the irradiation of the sun.

    We live on the earth with one half of the sphere facing the sun and the other half of the sphere facing away from the sun, and those who stay in the half of the sphere facing the sun live in the daytime, and those who stay in the half of the sphere facing away from the sun live in the night. Because the earth is constantly rotating, there is an alternation of day and night in every part of the earth.

    For example, we live in Guangzhou, China, and when Guangzhou is facing the sun, the citizens of Guangzhou are at noon. Since the Earth rotates from west to east, one cannot perceive the rotation of the Earth, but one can see the Sun slowly shifting from east to west. After 6 hours, the earth has turned 90 degrees to the east, and the citizens of Guangzhou are in the evening when the sun sets.

    The earth continued to rotate, and when Guangzhou turned to the position facing away from the sun, it was 0:00 a.m. in Guangzhou. After another 6 hours, the earth has turned 90 degrees, and the morning dawn is dawning in Guangzhou, and the day is coming. Later, when Guangzhou returned to the position facing the sun, the citizens of Guangzhou also returned to noon, thus completing a cycle of day and night.

    The rotation of the earth is responsible for the alternation of day and night. Because sunlight can only illuminate half of the earth, half of which is daytime and the other half is night, due to the rotation of the earth, there is an alternation of day and night.

    The sun is very far away from the earth, so it is fixed relative to the earth. When the Earth rotates from west to east every day, one time a day, half of the Earth is always facing the Sun and the other half is facing the Sun. Then, the half of the earth illuminated by the sun is day, and the half with the sun behind it is night.

    The combination of the Earth's rotation and revolution gives rise to the alternation of day and night, the changing seasons and the division of the five zones (tropical, north-south temperate, and north-south cold zones) on Earth. Since the Earth's axis of rotation is obliquely intersected with the plane of its orbit at an inclination of about 66°33, during the year when the Earth revolves around the Sun, sometimes the northern hemisphere of the Earth leans towards the Sun, and sometimes the southern hemisphere leans towards the Sun. The direct point of the sun always moves between the Tropic of Capricorn, so there is a change in the length of day and night.

    First, because the Earth is round and rotates, second, light travels in a straight line, and third, the closest stellar light source to Earth is the Sun. So the Sun can only illuminate half of the Earth, and other stars are too far away to use their light to bring the Earth to daylight brightness. So half of the earth is always daytime and the other half is night, and as the earth rotates, there is a day-night alternation.

    These problems are elaborated in secondary school geography textbooks, and they occur due to the different angles between the Earth's rotation and the Sun.

The formation of the primitive earth.

Before the formation of the earth, there were many asteroids in the universe revolving around the sun, and these planets collided with each other to form the primitive earth, when the earth was still a hot fireball, and as the collision gradually decreased, the earth began to cool slowly from the outside to the inside, producing a thin layer of hard shell - the earth's crust, at this time the earth was still in a hot state. A large amount of gas is ejected from the inside of the earth, which carries a large amount of water vapor, which forms a circle of atmosphere surrounded by the periphery of the earth, the position of the earth from the sun is not too close to the water vapor is evaporated by the sun, and the size of the earth itself has enough gravity to pull the atmosphere, so the earth will have a unique atmospheric environment, and the atmosphere begins to rain after the formation, and the original ocean is formed. >>>More
