What would be the impact if there was only night and no day?

If the earth has no magnetic field, the biggest change in life is that there is no life, and human beings will be extinct. The magnetic field resists the solar wind, which is an important reason why the earth can retain the atmosphere, and the atmosphere would be destroyed without a magnetic field.

The earth's magnetic field is formed due to the flow of liquid iron-nickel outside the core area of the iron core and the iron core, the magnetism can deflect the charged particles, the solar wind is wrapped in a large number of charged particles, if there is no magnetic field, the charged particles will have a fierce effect with the earth's atmosphere, ionizing a large number of gases, evaporating the ground water, and the earth's environment is no longer suitable for human survival. Mars is thought to have had a lot of flowing water, but due to the gradual cessation of core activity, the disappearance of the magnetic field, the atmosphere is stripped by the solar wind, and a large amount of water has evaporated, and the heat of the sun can no longer be retained, the temperature may become very low at night, and the temperature is higher during the day due to the sunlight directly reaching the ground.

The magnetic field also plays an important role in the earth's organisms, and there are many animals that may rely on the earth's magnetic field to identify the direction, such as birds, whales, etc., without the magnetic field, their activities will be affected, and a large number of organisms will become extinct, bringing about the deterioration of the global ecosystem. The earth's magnetic field extends far beyond the earth, protecting the entire earth's environment, and if the magnetic field disappears, the electronic equipment and satellite communication equipment made by humans can no longer work normally. When the sun erupts, it has some effect on the satellites in the Earth's orbit.

However, for life on earth, the most important thing may be liquid water, all life on the earth is inseparable from water, the magnetic field disappears, the atmosphere is stripped away, liquid water evaporates a lot, and the global life is gone.

In the absence of a geomagnetic field, a strong stream of charged particles (commonly known as the solar wind) emitted from the sun would not be deflected by the geomagnetic field and would hit the Earth. Under the bombardment of such energetic particles, the composition of the Earth's atmosphere may not be what it is now, and life will not be able to exist. Therefore, the "umbrella" of the geomagnetic field is very important to us.

There are many impacts, the most important of which is that plants and food cannot photosynthesize and grow, resulting in reduced food production and famine.

Human life becomes irregular and the body changes. The earth's environment and climate have changed dramatically, and many plants and animals will face extinction. The Earth has lost its main energy **, and it is possible that soon the Earth will become a dead planet.

Without daylight, there is no sun, no photosynthesis, plants cannot grow, and without plants, they cannot absorb the exhaust gases emitted by humans, which will affect the quality of the air.

The night of the earth is formed by the rotation of the earth, because the earth turns to the dark side of the universe, and the sun does not shine in this place, so the night appears.

The night on the earth is formed by the rotation of the earth, and the rotation of the earth will form the alternation of day and night.

Because the earth is round, when the sun hits one side of the earth, darkness forms on the other side, so night is formed.

According to the analysis of the program flow carried out by the computer simulation system, it can be seen that when the earth responds to the sun, one side is always day, and the other side is always night, so it can be seen that it will cause a large temperature difference, and there will be obvious thermal convection under the temperature difference, prompting the wind to blow from night to daytime

It will lead to a lack of photosynthesis in plants, which will make many things inconvenient at all and prone to traffic accidents.

The sudden disappearance of a day will cause panic in humans for a short time, but it will not affect much and will continue to maintain normal activities.

So as I just said, if the rotation and revolution reach the same time, there needs to be a phenomenon that occurs, that is, tidal locking, which is actually common in the universe - such as the moon, if the earth exists long enough, then the earth will eventually be tidally locked by the sun, so now it seems that it is because the moon is gradually moving away from the earth and absorbing part of the earth's rotation, so the earth's rotation speed is further simplified and accelerated, and it is tidally locked by the sun.

All this seems very beautiful and reasonable, but the habitable area of this continent is not large, because the atmosphere can only cover the area above 30 degrees north and south latitudes, and most of this continent is a plateau above 10,000 meters above sea level, if the earth is locked by the sun tides, it will gradually become a standard spherical shape, so that the sea water and the atmosphere can return to the lower latitudes, but the mantle is a solid with a high viscosity value, so this process must be very long.

Therefore, from the above point of view, assuming that the rotation speed of the earth is gradually slowing down, and it must be gradually and slowly slowing down - otherwise due to the sudden loss of its own weight, the speed is accompanied by inertia, everything on the surface of the earth will be thrown into the air, then it can be determined that animals and plants will basically be extinct, and the direct point of the sun must stay at the equator. The air near the equator is very thin, and the intense heat does not cause a strong flow in the atmosphere. In places where there is air, the heat of the sun is very limited, if this is the case of the day hemisphere, then the night hemisphere means that there is no sunlight at all, and because the night hemisphere is too far away from the direct point of the sun, the ocean heat input and output are relatively small, and the evaporation of seawater is also less, so there is no water vapor deep inland, so there is no precipitation on the inland It is very dry.

Eventually, the oceans will begin to freeze from the night hemisphere and gradually spread to this hemisphere, and it will be many years before the entire ocean will be frozen up, at which point the plants and animals on the planet, in our hypothesis, will be extinct for the second time, and it is uncertain whether there will be some surviving fish under the ice of the ocean.

This is the scene when the earth is always in the daytime, the species are extinct, the air is dry, the sea is frozen, and this is an extremely cruel world.

If there were only night left in the world, then life on Earth would be extinct on a large scale, and the Earth would be frozen in ice. Without food**, humans would also become extinct one after another.

If this were the case, then it is likely that many plants would die, because life would cease without the action of daylight, and then it would be time for us humans to perish.

Without daylight, people would not be able to correctly judge the 24 hours of the day, and they would definitely use too much electricity, with lights on when they go to work and street lights on the road.

Then our world will be dark, and many plants will die, because of the lack of photosynthesis, they will have a hard time growing, and we will also lack food, so we will also be very hungry, and we will not dare to imagine how we can spend the world without daylight.

It will make people lose hope of living. The day is a symbol of hope and the beginning of all good things, but the night gives people an endless sense of loneliness.

If there is only night left in the world, no, during the day I feel that people's lives will be disrupted, and there is only night life, which I can't accept.

There may still be many people who don't understand why there is day and night on the earth? Of course, this problem excludes the polar regions, because these two places have polar day and night phenomena in different seasons, because the earth does not exist in the universe upright, but in an oblique posture. The question of day and night comes down to the movement of the earth in the universe.

First of all, the Earth rotates all the time. What is the Earth's rotation? Earth's rotation refers to the Earth's rotation from west to east around its axis of rotation.

Because the Earth is approximately spherical, the Earth will face the Sun on different sides throughout the day, so there will be night and day. If you look at it from the North Pole, the Earth rotates counterclockwise, and if you look at it from the South Pole, it rotates clockwise.

It usually takes about 23 hours and 56 minutes for the Earth to rotate around in one cycle, which is why the day is 24 hours. Scientists have found that the speed of the Earth's rotation is not constant, and it increases or decreases by three-thousandths of a second about every 10 years. Such an error is not remarkable in a short period of time, but after millions or even tens of millions of years on the earth, the time of day on the earth will change relatively largely.

If the earth's self-transfer world has day and night, then the earth's revolution gives most of the world seasons. Like other planets in the solar system, the Earth orbits the Sun all the time. Because the Sun is not only the largest in the solar system, but also the most massive, the gravitational pull it generates binds the other planets to revolve around the Sun.

The Earth's orbit around the Sun is about 356 days, 5 hours and 48 minutes, which is why there are 365 days in a year.

The rotation and revolution of the Earth do not receive much attention, but their existence is significant. Think about it, if the earth does not rotate and revolutionize, a certain part of the world will always be in the day or night, and it will always be in the terrible of a season.

Because of the Earth's autobiography, the side of the Earth facing the sun is day, and the side facing away from the sun is night. No place is always daylight, only the North Pole in the summer and the South Pole in the winter, but not all the time.

The earth rotates to produce day and night. Within the Arctic and Antarctic Circles, it may always be daylight, known as the polar day.
