It is rumored that the axis of the earth was deviated when the Three Gorges was built, is it true?

A large amount of water storage on the earth's land, the relative reduction of water in the ocean, will inevitably produce a displacement of the original center of gravity on the earth, therefore, the speed of the earth's rotation and revolution will inevitably change, the Three Gorges Dam may have an impact on the earth's rotation center, but there are still a lot of water conservancy projects like the Three Gorges in the world, the Three Gorges water storage can not even enter the top ten, and a Three Gorges reservoir cannot fan any "wind and waves" on the earth.

The mass distribution of the Earth itself is uneven, moving away from the Sun at a certain rate every year, and the rotation speed is gradually slowing down, but this is due to many factors. The earth's crust itself is constantly moving, causing the earth's center of mass to constantly change, which is much more powerful than the change of center of mass caused by human engineering. Besides, although the current operation of the earth is gradually changing, it is very slow, and it may be that all human beings are gone, and her operation will not change much.

The flood level of the Three Gorges Dam is 160 meters, and it can't be lower, it's all money. Normal at 172 meters. Three Gorges Dam managers are conducting a 175-meter experiment.

It is expected to reach 180 meters in the future. 160 meters of water level, the Earth's offset reaches centimeters. The 170-meter water level Earth offset will reach centimeters, the 175-meter water level Earth offset will reach centimeters, and the 180-meter water level Earth offset will reach a staggering centimeter.

At the water level of 162 meters, the earth's offset is already the first in the world, and the current offset of 175 meters has far exceeded the foreign centimeter record, and the offset of 175 meters will not be overtaken in the next 50 years!

The construction of the Three Gorges Dam has indeed caused a large number of water bodies to converge, which has increased the mass of some areas, which may have a certain impact on the mass center of gravity of the earth, but there are still many water conservancy projects like the Three Gorges Dam in the world, such as the Hoover Dam in the United States. The Three Gorges is just a little bigger. When it comes to human impact on the earth, the most important thing is the atmosphere, water pollution, and land solid waste pollution.

It's still not a big deal for the planet, it's just not a good thing for the creatures of the planet. How many countries in the world have such a vast land area and such a rich water system? The Amazon River is rich in water, but it is a bit too abundant, and the construction of water conservancy projects on the main trunk is too complicatedThe difficulty is too high; Only the Yangtze River and the Yellow River in China and the Mississili River in the United States can meet the needs of large-scale hydropower projects, and at the same time have the strength to complete, or at least be located near a famous river on a continent.

Some countries with weather forecasts of "rain in the whole country" have no chance of building such a project.

According to the results of the survey, the Earth deviates from the sun's rays at a certain rate every year. This is definitely not just because of the Three Gorges Dam project.

Moreover, the amount of water in the Three Gorges Dam is equivalent to the impact of a drop of water on the entire sea compared to the amount of water on the earth, which is not the main reason for the displacement of the earth.

This is true, but it is not as exaggerated as people say, only a little off.

Not necessarily, there's no scientific basis for this, there's no evidence to prove it.

It is possible that our Chinese have the most ability to break the world record.

This is supposed to be fake, and there is no scientific basis to prove it.

This statement is false, this is just a rumor from people.

I don't know if this rumor is true, but the completion of the Three Gorges has had a great impact on the migration of fish.

This is not actually the case, this is just a rumor of people.

Earth science is called earth science as long as it is related to all spheres of the earth, mainly including physical geography (including soil science and remote sensing), geology, geophysics, geochemistry, atmospheric science, ocean science and space physics, as well as new interdisciplinary disciplines (earth system science, geoinformation science) and other sub-disciplines.

Geography, on the other hand, is the study of the earth's surface, which is closely related to human beings.

Geography focuses on the surface of the earth and the environment related to human existence, and a bit on the human aspect. Geology, on the other hand, studies the physical and chemical state and movement changes of the earth's various spheres, and focuses more on nature.

Therefore, many universities recruit liberal arts graduates in geography, and science graduates in geology, geophysics, geochemistry, oceanography, geophysics and other majors.

Geography is the study of topography and cultural landscapes above the surface.

Earth science is the study of the formation and evolution of the earth, including geological structure, plate drift, magmatic composition, etc.

Earth science is mainly the study of the geological structure of our earth, geography includes this, as well as human geography, physical geography, interdisciplinary and physical space, interdisciplinary and historical geography, etc., in short, the scope of geography is larger than that of earth science.

Geography includes the humanities, while earth sciences are studied with the structure and nature of the earth, with geography biased towards the liberal arts and earth sciences biased toward the sciences.

(1) Wind direction: northeast wind (2) In a rainy position: p Analysis:

The first question is crucial"Contour lines"This kind of question needs to draw a few more contour lines, mark the numbers, and you will see it at a glance! It is high pressure in the north, and the northeast wind blows by the geostrophic deflection force (right). Question 2.

On the basis of the first question, it is obtained: n is the ridge of high pressure, and p is the trough of low pressure ((rainfall) is affected by the northeast wind as a cold front, and the precipitation front is behind).

1.The wind direction is perpendicular to the isobar, you cross n to do the perpendicular line of the isobar, the wind direction is high pressure refers to low pressure, according to the latitude and longitude, so n is the northwest wind.

2.Or at N, M and P are respectively in the center of high pressure and low pressure, and a single air mass is controlled, and the weather is sunny, so MP is excluded; The rainy weather should be at the frontal position, and the isobar at n is flattened and close to the low-pressure trough line, so the weather at n should be frontal and rainy. Q is inside the high pressure and far away from the low pressure trough line, so it should not be rainy weather.

1 Northerly or northeasterly wind. If the n pressure is higher than the p, the north of the isobar line is high pressure. Wind direction high pressure refers to low pressure, and the northern hemisphere is biased to the right. Combined with the warp, it can be judged. The second question on the first floor is very clear. The edge of the ridge is a front. Most of the fronts have rain and snow.

Earth science is a basic discipline that studies the processes and changes of the earth system (including the atmosphere, hydrosphere, lithosphere, biosphere and solar-terrestrial space) and their interactions. It mainly includes sub-disciplines such as geography (including soil science and remote sensing), geology, geophysics, geochemistry, atmospheric science, marine science and space physics.

To put it simply, it is a discipline that studies the earth and the solar system on a macroscopic scale.

Geography is mainly the study of nature (climate, geology, etc.), and belongs to the category of natural sciences, rather than humanities and social sciences. This can be proved by the geography-related majors in the university, compared with the middle school, the knowledge of the university is wider, more comprehensive, and more practical, so it can be concluded that the study of geography belongs to the natural sciences, so it is a science.

However, in middle school, we classify geography as a liberal arts subject, and the college entrance examination for liberal arts and sciences is also a liberal arts student who takes geography, but when it comes to college, geography is classified as a science subject, and the related majors are all science majors such as address exploration and remote sensing mapping.

As for Earth Sciences, I can tell you for sure that it's a humanities discipline because I'm from the Earth Sciences Department
