The reason why the earth rotates slower in winter and faster in summer is because of the cyclical nature of the earth's rotation, and the speed of rotation is the sameTidal phenomenaMatter.
The National Institute of Standards and Technology (NIST) observed a slow trend towards the Earth's rotation speed over a long period of time.
Accelerated from 1999. NIST's timer.
It's called the Time Atomic Clock.
In the 27 years from 1972 to 1999, a total of 22 standard Earth clocks were added. But there was no leap second after 1999 because the speed of rotation of the Earth increased. <>
From the beginning of the 20th century, an important astronomical discovery was the confirmation that the Earth's rotation speed was uneven. There are three variations in the speed of the Earth's rotation: a long period of deceleration.
This change increased the length of the day by about 1-2 milliseconds in a century (about 1 second every 35,000 years) and slowed the time measured in 2000 by more than 2 hours, as measured by the Earth's rotation period. The main reason for the slow rotation of the Earth is tidal friction. Scientists have found that during the Middle Devonian period 100 million years ago, the Earth lasted about 400 days a year.
Cyclical changes. Through the analysis of astronomical time measurement data in the 50s of the 20th century, it is found that the earth's rotation speed has the characteristics of seasonal cycle change, slow spring, fast autumn and semi-annual cycle change. The annual variation is about 20 25 ms, which is mainly caused by seasonal changes in wind.
Irregular changes. There are also irregular changes in the rotation of the Earth. The reasons for this need to be further analyzed and studied.
The factor of conservation of momentum should be the main reason for the slow rotation of the Earth at present. <>
Changes in the Earth's rotation speed are closely related to human activities. It's like an artificial Earth satellite.
of the launch, its reaction force.
Causes the Earth's rotation to be directly slowed down.

Winter, summer, autumn and winter have nothing to do with the rotation of the earth, only with the revolution. The rotation speed is the same. The Relativity Time Study will be happy for you!! Thank you.
-
In winter, the earth rotates fast. That's why we feel like winter time flies. This is because our time is essentially a physical representation of the Earth's rotation. The earth rotates slowly in summer. It's because the earth is moving away from the sun.
-
It's the same, except that the Earth is not the same as the distance from the Sun, and the Earth's orbit around the Sun is an ellipse.
-
Maybe, but that's for the future, and it won't happen yet.
-
The Earth's rotation is getting slower and slower, will the **peak come earlier? Is there a scientific basis?
-
Yes, time and space are closely linked to the movement of objects, and for me personally, time is the product of the movement of objects, and space is the state of motion of objects, because of the presence of the sun, there is a diurnal variation, as I said above. Time is the product of the motion of an object, and the amount of this product is certain, if the speed of the object's motion changes, then the time it can produce will also change, it is precisely because of the existence of the sun, which limits our thinking, even scientists are no exception, the famous physicist Albert Einstein said in his special theory of relativity, the speed of the object increases, and even time will slow down.
For example, if you are interested in the content of the lesson, the lesson will pass quickly, and if you are not interested and you just want to get out of the lesson, the lesson will pass slowly.
So yes, the slower the Earth's rotation speed, the faster time becomes.
-
The Earth's slow self-rotation makes the Earth's day-night time longer, and the Earth's self-transformation slows down by about one hour every 200 million years.
Other words; 200 million years later, the Earth has 25 hours of day and night.
-
The rotation of the earth slows down, and time slows down, because the earth revolves around the sun, and the rotation speed slows down, and the change of day and night also slows down, and time slows down. Thank you.
-
No, it's just an extended day.

It should be a question about Einstein's theory of relativity, when an object has traveled close to the speed of light, it can go to the future.
It needs to be understood that when you fly at the speed of light, you will feel that one second is a long time, but at normal speed, we will feel that one second is very short, but this will create a time difference, if you fly at the speed of light, after a second, the world at normal speed may have passed a few minutes. Now, scientists have also put forward the idea that the greater the gravitational pull, the slower time passes, for example, if a person stands on the ground and another person stands on a very tall building, then I will see people on the ground, walking very slowly, but this effect is very weak, because the earth is very weak and weak relative to the black hole, so weak that you don't believe it. In the end, we came to the conclusion that when the earth's self-rotation slows down, the gravitational force we experience will increase, because the centripetal force will decrease, our time will slow down, and the slowdown is because we look outside the earth, but we think that the watch is normal, and the things outside the earth will become faster, so the time will become shorter, because the sun sets very quickly, and the day is less than 24 hours, and this change is very weak, just a few microseconds of change!
At this time, there is a fallacy, why? According to our common sense, the earth's self-transformation is slow, the sun will shine on the earth for a longer time, our 24 hours a day, it will no longer be, maybe it will become an hour a day, in this way, the time will become longer!
-
First of all, time is relative, so due to the slow self-transformation of the earth, resulting in an extra second in a year, we can only reduce the time of each day to digest this extra second.

When discussing the duality of labor, Marx pointed out sharply that under the conditions of capitalist large-scale machine production, labor has a duality, creating beauty and non-beauty at the same time. “…Labor produces miracles for the rich, but abject poverty for the workers.
Labor produced the palace, but created sheds for the workers. Labor creates beauty, but it makes the worker deformed. Labor replaces manual labor with machines, but returns one part of the workers to barbaric labor and turns another part of the workers into machines.
Labor produces wisdom, but it produces dullness and dementia for the workers. Although Marx did not directly answer the question "what is beauty" or how labor creates beauty, it has already implied a logical premise: in order to answer the essence of beauty, we must first answer the essence of man and the nature of labor.
Here, Marx has raised the essence of beauty to the level of philosophical anthropology, thus establishing a higher-level logical starting point, and aptly determining the status of relevant aesthetic issues, including the proposition that "labor creates beauty", in the Manuscript. There is a famous philosophical fable in ancient Greece, the mystery of the Sphinx, which tells us to "know thyself". Since the beginning of human history, people have never given up the understanding and exploration of "self", and the continuous deepening of self-knowledge is also the continuous deepening of human self-consciousness.
Aristotle defined man as "the animal of the polis"; Thomas Aquinas said that "man is God's chosen people"; During the Renaissance, man was regarded as "the measure of all things", "the essence of the universe, the primate of all things", and so on. Regarding the essence of man, it is customary to quote Marx's two definitions, one of which is that "in its reality, the essence of man is the sum total of all social relations." "The other is:
The essence of man lies in the "conscious life activity", in which "man makes his life activity itself the object of his own will and his own consciousness." He has a conscious life activity.

I think the time should be longer, and the slower self-transformation will lead to longer days and nights. As a result, the day and night will be longer.

Because the Earth's axis is tilted, the Earth's rotation causes the Northern Hemisphere to have longer nights than days in winter. In the Southern Hemisphere, it is the opposite, the day is longer than the night in winter The earth has a yellow and red angle, yellow is the direct point of the sun, the red is the equator, because of this, there is a Tropic of Cancer 23 degrees 26 minutes, the direct sun point will move between the Tropic of Cancer throughout the year, in winter, the sun directly hits the beam limb point on the Tropic of Capricorn, at this time the Antarctic polar day, the North Pole polar night, and the equator throughout the year day and night silver manuscript bisect, in winter, the morning and dusk rubber line cut the earth as if a knife, at this time most of the northern hemisphere is covered by night.
Trouble, thanks!

How was the Earth's rotation discovered?
-
You might not expect that if the Earth were spinning faster, the Earth's climate would be milder – at night, before it reaches a realistic low, it will start to rise, and during the day, it will start to drop before it reaches a realistic high. Conversely, if the Earth's rotation is slower, the Earth's climate will be worse – at night, the temperature will drop lower than it is real, and during the day the temperature will rise and dissipate faster than it actually is.
Over the past 10 million years, the Earth's rotation speed has been largely stable, so the Earth's climate has always been pleasant. Nowadays, the earth often has extreme sock climates, and some processes are actually self-regulating processes of the earth's rotation speed.

The Earth is the solar system.
in the eight planets.
One orbits the solar system, and the time in it is called the revolution, which is commonly known as the time of the year. And the earth itself rotates along its axis of rotation, which is the time of our day. Among them, the revolution has little impact on a planet, and the biggest impact on a planet is the rotation of a planet.
If the speed of this rotation is faster, it will cause the day to be shorter, and if the rotation speed is slow, it will cause the day to be longer.
For example, our earth's rotation time has become faster and faster, but because we are in the earth, we are often unaware of it, so what will be the effect of the rotation becoming faster and faster? One of the biggest effects, of course, as mentioned above, is that time is getting shorter and shorter. However, it is not excluded that there will be other hazards, such as **, the latest research has found that the slow self-transformation of the earth will lead to more and more times every year.
Just last year's Geological Society, scientists on this move out of the record, with the display of these data, we can clearly see that with this year's rotation is getting faster and faster, this year there will be a number of strong earthquakes, the result is true, this year not only Japan and other ** multi-occurrence countries ** number of increases, even rarely appear ** Taiwan Strait.
There is also a **, and the level is not low, even the neighboring Guangdong Province and Fujian Province can feel the earthquake.
So as this continues, the level of ** may become more and more advanced, which is something we don't expect, so what is the reason why we are spinning faster and faster? Some scientists said: This may be the geomagnetism of our earth.
Place, but in fact this statement is not available to scientists.
Getting faster is its own behavior, and in the past, the time on Earth was only 18 hours, but now it is gradually exceeding 24 hours.
And in the process, along with the moon.
Gradually detached from us, the rotation speed of the earth, which has lost the tidal effect, is even more unlimited, so the reason for the faster rotation speed appears.
-
Yes. Because the faster the Earth's rotation, the shorter the time to rotate in one cycle, so the time of day will also become shorter.
-
Yes, we know that the time of day is determined according to the speed of the Earth's rotation, and if the rotation speed is getting faster and faster, then the time will definitely get shorter.
The reason why we generally feel dizzy on rotating objects is not because of the centrifugal force generated by the rotation of the object itself, but because the centrifugal force generated by rotation will be uneven and variable in magnitude and direction. >>>More
The sun is fast, it is the sun that catches up with the moon. Judging from the solar eclipse, it is the moon that begins to obscure the sun from the west. In this case, it's simply to shade the sun from above.

If the indoor ventilation is not good or the temperature is too low, the paint will dry slowly. At this point, you can open all doors and windows to promote ventilation, or put a heater in the room to increase the room temperature. If the problem persists, it may be that the painted surface is greasy. >>>More
Aloe vera prefers fertile and well-drained soil and can be grown with a mixture of 7 parts peat or humus and 3 parts perlite or river sand. In daily watering, we must remember not to water too often, follow the principle of seeing dry and wet, you can give it more direct sunlight in spring and autumn, and we had better put it indoors in a sunny place in winter.
