1. The earth's axis is a line segment imagined by human beings, set to describe the convenience of the earth's rotation, not an entity, and does not exist in reality. The earth's axis has been in flux, but the range of change is small, except for the impact on the evolution of the earth's celestial bodies and geological phenomena in millions of years, in daily life, it can be ignored;
2. **, the earth is happening all the time, it is an extremely natural geological phenomenon, we usually don't feel it, and what we feel belongs to the feeling**, very little. It's just that farting can break the heel, and the interaction between the earth's axes is not great.
3. The earth's axis, the center of the earth, and the earth's crust have been changing and moving since the birth of the earth and the earth's crust, so that they have formed the way they are now. Since the day of formation, the earth has been in a state of cooling, the crust is getting thicker and more stable, and after the heat in the earth's interior is dissipated, a solid rock sphere will be formed, and then you will be more at ease. Hehe, but that's 3 billion years from now.

It is not that the Earth's axis is tilted, but that the Earth's orbit around the Sun is parallel, and the Earth is tilted and rotated (and revolves in this way), and the angle between the Earth's axis and the ecliptic is 66 degrees 34 minutes.
If the Earth's orbital plane is used as the research center, and it is horizontal, then the ecliptic plane is oblique, and the angle between the Earth's axis and the ecliptic plane is 66 degrees 34 minutes. That is, the angle of yellow-red intersection is 23 degrees 26 minutes.
So the key to whether the Earth's axis is tilted or not lies in your reference (the research center).

The imaginary axis of the Earth's rotation...
The Earth is constantly orbiting this imaginary axis. Therefore, it is also called the earth's axis of rotation.
This axis connects the north and south poles through the center of the earth, and has an angle of 66°34 with the Earth's orbital plane.
The Earth's axis is always facing the North Star.
The plane that passes through the center of the earth and is perpendicular to the earth's axis is called the equatorial plane.
-
A fictitious axis connecting the Earth's poles perpendicular to the plane of the equator.
-
A virtual axis that passes perpendicularly through the north and south poles.

The change in the Earth's axis is almost negligible, and Japan** has slightly changed the Earth's mass distribution, causing the Earth's shape axis to shift by more than centimeters. However, the offsets associated with ** are smaller than those caused by the natural changes in the atmosphere and oceans. Will the shift in the Earth's axis of rotation lead to climate change?
In short, no.
-
No inclination almost no change throughout the year.
-
The tilt of the Earth's axis causes the direct sunlight to migrate between the Tropic of Capricorn, and the light received at the same place at different times is different, thus producing four seasons.
-
If it is not tilted, the direct point of the sun is fixed at the equator, the heating of all regions of the earth does not change all year round, the climate base does not change, and the climate change from the equator to the poles is summer--- spring (autumn) - winter, if there are four seasons at that time. Of course, this is the ideal situation, and if the earth does not tilt, the earth's atmospheric circulation and other cycles will completely change, and these are the things of experts and scholars.
-
If it is not tilted, then the direct point of the sun is always at the equator, and the temperature on the earth decreases from the equator to the poles.
-
Due to the tilt of the geographic axis, the angle of the sun's elevation at noon varies from place to place every day. When the solar altitude angle is the largest, the solar radiation received per unit area is more, and the temperature is the highest in the year, which forms the local summer. The opposite is winter. After one revolution of the earth, one cycle is completed, and the next cycle begins.
On the contrary, if the earth's axis is not tilted, then the height of the sun at noon every day of the year on the earth will not change, the solar radiation received every day is the same, and the temperature will be the same, there will be no difference between the four seasons, there will be only one season in each place, the equator and places within 30 degrees north and south latitude will always be summer, and places above 60 degrees north and south latitude will always be winter.
-
Because the seasons change, it moves.
-
The tilt of the earth's axis causes the direct point of the sun to not be fixed near the equator, but has a considerable range of changes, resulting in the earth's temperature changes in the four seasons, as well as the resulting changes in precipitation, wind, air pressure, climate, etc.

The earth's axis itself is an imaginary axis, which refers to the axis around which the earth's rotation revolves, the intersection point of the north end and the surface of the earth is the North Pole, and the intersection point of the south end and the surface of the earth is the South Pole. This axis is not perpendicular to the Earth's orbital plane, but has an angle of 66°34. The position of the earth's axis in the earth is not fixed, but there is a slight movement, resulting in "pole shift", and this phenomenon of the earth's axis moving and tilting is called the earth's axis tilt.
Since the Earth's axis is an imaginary axis of the Earth's rotation, the most direct effect of the change in the Earth's axis tilt is to change the time of day of the Earth. Scientists say that due to the change in the weight distribution of the earth due to the large **, the earth's rotation speed has changed, and the Chilean ** has caused the earth's axis to move by 3 inches (8 centimeters) and the axis of rotation to shift milliarcseconds (milliarcsecond), thus shortening the human day by microseconds, that is, millionths of a second, although the change is minimal, but the change is permanent.
Similar changes have happened before. In 2004, Indonesia caused the Indian Ocean tsunami, which reduced the daily time by microseconds. In turn, events that lead to an increase in the number of hours per day are also possible.
If the Three Gorges Reservoir were fully filled, it would store 10 trillion gallons (40 cubic kilometers) of water, and the weight would increase by microseconds per day.
In addition, the angle of the Earth's axis shift also affects the polar day and night phenomena and the position of the Tropic of Capricorn.
At the same time, the researchers are also focusing on whether the shift in the Earth's axis of rotation has an effect on the Earth's gravitational field.

There will be no effect, and the impact of humans on the Earth's interior is negligible compared to the movement of the Earth's interior and the movement of the Earth's crustal plates. Unless there is a displacement of a very massive object on the Earth, the tilt of the Earth's axis does not change. Nowadays, a large number of automobile buildings have the most impact on the composition of the atmosphere and the microclimate of local areas, that is, they have an impact on the atmosphere, and have no effect on the earth's interior at all.

There are many factors that can affect the angular position of the Earth's axis, such as some extreme climate disasters, such as tsunamis, **, etc. Giuseppe Bianco, a geodesy expert at the Italian Institute of Space Technology, has found that the magnitude of the strong** and the resulting tsunami caused the Earth's axis of rotation to "shift". But scientists also believe that because the Earth's rotation cycle often changes slightly, the impact of the Indian Ocean on it may be short-term and not too significant.
Scientists at the National Aeronautics and Space Administration (NASA) of the United States say that the 2010 Concepción** magnitude in Chile may have driven the Earth's axis to shift. According to Richard Gross, a geophysicist at the Jet Propulsion Laboratory in California, USA, who used a computer model to estimate the effects of a strong earthquake in Chile, he said that a strong earthquake can displace hundreds of kilometers of rocks by several meters, causing changes in the mass distribution of the earth, which will affect the rotation of the earth. Gros said Chile's ** may have shifted the Earth's axis of rotation by milliarcseconds.
Researchers at the British Institute of Geological Research explain this phenomenon by referring to the "skating effect", saying that if the skaters turn their arms in as they spin their bodies, they will spin faster and faster. In the same way, the rate of rotation changes as soon as the mass distribution of the Earth changes during its rotation, but such small changes are difficult to detect.
If you want to start a business, it is recommended that you choose a suitable entrepreneurial project, see if you have the qualifications of the relevant project, and work hard after finding the right project. Of course, capital is also a problem to consider in the process of starting a business, and if you have limited start-up capital, you can solve it through small loans. >>>More

Feelings are a matter of two people, and you shouldn't think too much about other people's opinions. Of course, if it is a reasonable opinion of the family members, it should also be properly considered, that is, if two people feel that there is no big problem in both material life and spiritual life, there is no need to affect your relationship because of some words from others. The road to any relationship is not smooth sailing. >>>More
