Why is the earth so big and can turn, and why is the earth so big?

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.

And if you ask why the Earth is so big, I don't know Zuma, because the Earth is still pitifully small compared to other planets.

The power of the earth's rotation is external, it is the combined force of the solar wind and the walking wind that activates the earth's wind wheel and water wheel, and the earth rotates from west to east under the direct drive of the wind wheel and water wheel. The earth itself cannot rotate, nor can it not rotate, how it turns, how it turns, how fast it turns, and how it turns slowly, all depend on the vector and the resultant force of the outer circles, which is the real reason for the phenomenon of "the earth is rotating". To distinguish it from the theory that the earth rotates on its own, I will briefly call it the "wind blowing the earth and the earth turning".

See below for a detailed explanation.

It has a surface area of about 100 million square kilometres, a volume of about 1,080 billion cubic kilometres and a weight of about 60 trillion tonnes. If you go all the way south from its northernmost North Pole, it would be 20,000 kilometers to reach its southernmost South Pole. For such a long distance, if you walk 50 kilometers per day, you have to walk continuously for 400 days; If you take a jet that can fly 800 kilometers per hour, it will take you 25 hours to arrive.

And that's only half a circle of the Earth. If we follow its largest parallel, the equator, to the east or west, to fly a full circle, and then return to the original starting point, it will take more than 50 hours, and we will have to fly for more than two days in a row. It took nearly three years for the navigator Magellan to lead a fleet around the earth.

The size of the earth can be imagined. If we compare the area, the entire earth's area is equivalent to 53 times the area of China's territory and 2,000 times the area of the British mainland. But only 29% of the Earth's surface is land, and 71% is ocean.

Is the earth big, I don't feel it. It's just a small ball of the universe that houses more than 60 billion people.

All the planets rotate on their own, and some rotate slowly

My personal opinion is that when the Earth first formed, I had several violent impacts that caused the Earth to spin, and because of inertia, there was no resistance, so it kept rotating.

Why does the Earth rotate?What is the reason for the rotation?The power of rotation is obtained from **

Why did you choose the current direction, attitude, and speed rotation?These are all problems that modern science has not solved so far. It does not require the repetition of the proven natural phenomenon of "the earth is rotating", but it requires the understanding of the reasons behind the phenomenon of the earth's rotation, and the dynamics of the earth's rotation** and its constraints.

The "rotation of the earth by itself" is already explaining the reason for the rotation of the earth, and it is necessary to affirm that the driving force of the earth's rotation lies in "itself", in the internal force of the earth rather than outside, and in the internal force it has rather than the external force. To deny that "the earth rotates on its own" is not to deny the phenomenon that "the earth is rotating", but to deny that there is a power inside the earth that pushes itself to rotate, just as the power of the rotation of a water mill does not lie inside the grinding body.

Therefore, "the earth is rotating" is not the same as "the earth is rotating on its own", they are two different concepts, and if the two are carefully observed together, it is a kind of "misconception". All planets rotate.

The rotation of the earth is necessary to maintain the attitude of the earth. If the earth does not rotate, it cannot be in a stable orbit, and there may be no human beings on the earth.

The Earth's rotation, like other planets, is created by the impact of countless objects when it was formed. As you can imagine, a large pile of interstellar matter is gravitationally applied to many sides and hits the Earth's primordial sphere in a sideways direction. It's a lot like a child whipping a dhara.

How big is the Earth?It is estimated that many people will think that it is so big and big that the brain capacity is unimaginable.

But perhaps the right question is: how small is the Earth?

After reading the position of the earth in the universe, will you feel fear, will you feel that people are so small? Yes, Earth is an insignificant asteroid to the Milky Way.

But on our scale, all the stars you can observe are only within the confines of the Milky Way.

Let's take a look at what's in the other galaxies?

The space telescope, Hubble, points its lens at a small corner of the night sky.

Even all of this is just a wave of light. Each of us is a grain of sand in the universe, it seems so small and insignificant, compared to the vast universe, what is the point of our own troubles?

So be sure to live each day happily and don't let the worries distract you!

Because of the vastness of the earth, Earth is one of the eight planets in the solar system, ranking third in order of being from near to far from the sun, and it is also the terrestrial planet with the largest diameter, mass and density in the solar system, 100 million kilometers away from the sun. The Earth rotates from west to east while revolving around the Sun.

The Earth is not very big, and many planets are bigger than the Earth.
