What if the Earth rotated from north to south?

If you turn from north to south, the earth will still have a difference between day and night because of the revolution, and the orbit of the revolution is also from west to east, so the sun will rise in the east and set in the west, but one day = one year, and at the same time, due to the change of the geostrophic deflection force, the atmospheric circulation and the ocean circulation will change significantly, and the change in the length of day and night will also cause great changes in the environment.

Aren't you talking about Uranus?

The following ** is from the encyclopedia.

The axis of rotation of the planet can be said to lie on the plane of its orbit, with an angle of inclination of up to 98°, which makes his seasonal changes completely different from those of other planets. The rotation of the other planets is facing upwards relative to the orbital plane of the solar system, and the rotation of Uranus is like a ball that has been overturned and rolled over. When Uranus is near the solstice, one pole will point continuously towards the Sun and the other will be facing away from the Sun.

The rapid alternation of day and night can only be experienced in a narrow area near the equator, but the position of the Sun is very low, as if in the polar regions of the Earth. When running to the other side of the orbit, the other pole of the axis is pointed towards the sun; Each pole will have a polar day that lasts for 42 years and a polar night for the other 42 years. As the Sun faces Uranus' equator as it approaches the equinox, Uranus' day-night cycle will be similar to that of other planets, and on December 7, 2007, Uranus will pass through the equinox.

Solar terms on Uranus:

Northern Hemisphere years Southern Hemisphere.

Winter solstice 1902, 1986 Summer solstice.

Spring equinox 1923, 2007 autumn equinox.

Summer solstice 1944, 2028 winter solstice.

Autumnal equinox 1965, 2049 vernal equinox.

One consequence of this axis pointing is that over the course of a year, Uranus' polar regions receive more energy from the Sun than from the equator, but Uranus' equator is still hotter than the polar regions. The mechanism that causes this outcome is still unknown; The reason for Uranus' anomalous tilt is unknown, but the common assumption is that a protoplanet the size of the Earth hit Uranus at the time of the formation of the solar system, causing the tilt of the direction. In 1986, when Voyager 2 flew by, Uranus' south pole was almost facing the Sun.

The marking of this pole as the South Pole is based on the definition of the International Astronomical Union: the North Pole of a planet or moon is pointed above the invariant plane of the solar system (not determined by the direction of rotation).

That is, half of the earth will always be day, and half will always be night, and this is the biggest change. The premise is that the revolution does not change.

If we continue to take the Earth's axis of rotation as an indicator of the north-south direction, and still think that the direction of the Earth's rotation is from west to east, if these stubborn concepts are not first discarded, then no matter how the direction of the Earth's axis changes, we can only come to the only conclusion that the Earth rotates from west to east.

What would the world become if the earth rotated from east to west?

Because the north and south poles are viewed from above.

The Earth is constantly rotating from west to east on its axis, with the northern end of the axis pointing above Polaris. When viewed from the North Pole, the Earth's rotation is counterclockwise, whereas from the South Pole, it is the southern end of the Earth's axis, opposite to the northern end, so the Earth's rotation is clockwise.

Observing the rotation of the earth in different directions, the direction of the earth's rotation is of course different.

For example, if you stand on the side of an east-west road and look at passing traffic, if you stand on the south side of the road, the traffic from west to east is moving from left to right. If you look from the north side of the road, the car from west to east is going from right to left.

The Earth's rotation is the same when viewed from both poles. No matter how the Earth rotates, the direction is from west to east. But when you look at the North Pole, it's counterclockwise from west to east. And when viewed from Antarctica, this direction is clockwise.

The Earth rotates from west to east, so from the South Pole, it is clockwise, and from the North Pole, it is counterclockwise.

Using a globe as an analogy, it should not be difficult to understand that when it rotates from west to east, it is counterclockwise over the North Pole and clockwise over the South Pole.

The direction of rotation of the Earth does not change, i.e. from west to east. If viewed from the North Pole, it is counterclockwise, and if viewed from the South Pole, it is clockwise.

The Earth rotates from west to east on its axis of rotation, rotating counterclockwise from the North Pole and clockwise from the South Pole.

Let's look at a ping-pong ball or something that's round, and we'll get to the point.

When viewed from above, when the sphere rotates counterclockwise, when viewed from underneath the sphere, it rotates clockwise.

We know that almost all celestial bodies in the solar system, including asteroids, rotate according to the law of the right-hand rule, and the rotation of all or most celestial bodies is also the right-hand rule. Why? The predecessor of the solar system was a dense cloud, driven by a certain force that attracted each other, and this accretion process made the density gradually larger, which accelerated the accretion process.

On the one hand, the centripetal accretion accumulation becomes the sun, and on the other hand, the gas gradually develops into a flattened shape, and in the process of development, the potential energy becomes kinetic energy, and finally the whole thing turns. At the beginning of the rotation, there are those who turn this way, and those who turn that way, after a certain direction prevails, they all become one direction, and this direction is the right-hand rule that is now discovered, and there may be other solar systems that are left-handed rules, but in our solar system it is the right-hand rule. The energy of the earth's rotation** is caused by the eventual transformation of material potential energy into kinetic energy, which ultimately means that the earth rotates on the one hand and rotates on the other.

The rotation of the Earth does not stop, although there is acceleration, it will get smaller and smaller, and it will not reduce the angular momentum to 0.

If only the Earth-Moon system is considered, the deceleration limit is the synchronous rotation of the Earth-Moon due to the conservation of angular momentum, as in Pluto. This is the reason why the moon always has only one side facing the earth, but because the moon is small, the earth is large, and the moon's tidal effect on the earth is small, so the earth is not relatively stationary now, but one day it will still be, and then there will be no tidal action between the earth and the moon. But don't forget that there is relatively no rotation between the Earth and the Moon, but there is still a rotation relative to the Sun, so the Earth's rotation will not stop.

Some of my previous explanations were wrong.

In the subject of geography, we will learn the knowledge of the rotation of the earth, because of the rotation of the earth, so there are a lot of rotation meanings, because the earth does not shine and is not transparent, so the alternation of day and night is the meaning of the earth's rotation. In addition, the meaning of the earth's rotation also includes local time and regional time, so is the direction of the earth's rotation from west to east?

1. The direction of rotation of the earth is from west to east. The rotation of the earth means that the earth rotates from west to east around the axis of rotation. The rotation of the Earth is an important form of movement of the Earth.

During the first attack on the Earth's rotation, if the Earth's rotation is seen above the South Pole, then the rotation is clockwise; If you are looking at the Earth's rotation from the North Pole, the direction of rotation is counterclockwise.

2. The rotation of the earth is an important form of motion of the earth, the average angular velocity of rotation is in degrees and seconds, and the linear velocity of rotation at the equator of the earth is 465 meters and seconds. It takes 23 hours and 56 minutes for the Earth to rotate around and increases or decreases by 3 to 4 thousandths of a second every 10 years.

3. The rotation of the earth also causes objects that move horizontally in any direction on the earth to deviate from the initial direction of their motion. If the moving object is oriented in the direction of travel, the horizontal object in the northern hemisphere is biased to the right, and the southern hemisphere is biased to the left.

4. The reason for the deflection of the direction of motion of horizontal objects on the surface is that objects have inertia and try to maintain their own speed and direction. As mentioned above, the horizontal direction of the earth is based on the meridian and the parallel, the direction of the meridian is the north-south direction, and the direction of the latitude line is the east-west direction.

5. However, due to the rotation of the earth, the meridians and latitudes, which are the standard of north-south and east-west directions, are deflected with the autobiography of the earth. As a result, the horizontal motion of an object that really maintains the same direction is deflected relative to the direction on the earth.

The above is an introduction to whether the direction of rotation of the earth is from west to east.

If one day our planet starts to rotate in the opposite direction, the Earth will continue to rotate from west to east around its axis, and it will no longer be the Earth as we know it. You don't notice that our planet rotates at the equator at a speed of 460 meters per second, which is very fast, and a sudden change of direction can cause catastrophic winds and huge waves, these abnormal weather conditions destroy almost everything on the ground. Let's skip this devastating shift and imagine that our planet reversed its course billions of years ago.

You will see the sun and moon rising in the west and setting in the east.

In the south, but none of them will be as dry as the Sahara Desert is now. There will be more vegetation on the planet. This will bring us more oxygen, but those who live in Western Europe will be hit, the Pacific current will push a lot of cold water, which will bring cold winters to the region, on the other hand, Russia will warm and take away the relief from the coldest country on the planet.

The Earth will also be different in the oceans Billions of years ago, cyanobacteria would dominate other phytoplankton species Oxygen-absorbing cyanobacteria invented photosynthesis and changed the atmosphere of our planet Probably more cyanobacteria on Earth would alter the atmosphere and even further fill us with too much oxygen to make us even exist.

Let's let the Earth rotate the way it is, you will never believe that the Sahara Desert is a desert How different our planet will be In short, the reverse rotation will make the Earth greener , This new rotation will change the winds and ocean currents, which will change the climate of the Earth entirely The oceans act as a global climate control system that spreads the heat of the sun all over the planet.
