How does the Earth rotate?

Our universe exists about 13 billion years. The first chemical elements that formed in it were called hydrogen and helium. Later, the emergence of nuclear reactions led to the formation of new elements. Existing stars exploded and dispersed in outer space clouds of dust and gases, which 5 billion years ago led to the condensation of one cloud. This cloud thickened, it grew larger until it flared up and formed a star, which we now call the Sun.

solar system

The sun is a star that plays a central rolein the solar system. This star is also the largest and most massive object in the solar system, which contains more than 95% of the mass of the entire solar system. The rest of the weight of the solar system falls on other objects that revolve around the Sun: Jupiter, Saturn, Uranus, Neptune, Pluto, Earth, Venus, Mars, Moon, Mercury. Because of its huge mass, the Sun has a powerful gravitational field that can hold together all the bodies of the solar system and control the movement of the planets around the Sun in its orbit.

Formation of the planets began about 4.6 billionyears ago. They were formed from a substance that was closest to the Sun. The planets are divided into stony and gas. The stony planets include Mercury, Venus, Earth and Mars. The gas planets include Jupiter, Saturn, Uranus and Neptune. And Pluto - a planet that was furthest from the Sun, is completely unusual, since it is a solid ice planet with a stone core inside.

Our Earth

The planet Earth is a very unusual planet,which was formed from a disk-shaped cloud, dust and gases, a stellar matter left after the birth of our Sun. Planet Earth is one of the nine planets that are in the solar system. How does the Earth rotate? This is a very interesting process, since the Earth rotates not only around its axis, but also around the Sun, thanks to which we can observe the day, year and seasonal temperature changes on our planet. The second question immediately arises: at what speed does the Earth rotate?

We are referring to observers, it seems thatThe sun and the stars themselves move in the sky according to the earthly hour. It seems, it seems, if the day, the Sun is at the very center of the sky, in another way this is called the hottest time of the midday Sun - the sun. And if it is evening, then it descends to the horizon. Almost the same situation occurs with the stars. But in fact, it turns out that the Earth is spinning swiftly, making one full turn around itself within a day. Thus, in that part of our planet that is turned towards the Sun, the day comes, and in that which is closed from the Sun, it is night. So it turns out that morning, day, evening and night last for 24 hours. During this time, the Earth makes a complete revolution around its axis, and then everything is repeated anew.

But, as we remember, the Earth also rotates aroundThe sun. But how, I wonder, she does it? How does the Earth rotate around the Sun? This process is long enough if it is measured in terrestrial time, as one complete revolution around the Sun the Earth performs for 365.25 days, which, in turn, is one full earth year. Depending on the position of the Earth relative to the Sun, we can observe 4 seasons on our planet: spring, summer, autumn and winter.

If the Earth stops

One of the most relevant and at the same time complexquestions is this: when the Earth stops rotating? But in addition to the fact that this issue is very complex, it still has no answer. Scientists find it difficult to predict when this can happen.

And if we hypothetically imagine that our Earth will stop, what will happen then? Let's try to imagine.

If the Earth abruptly stops spinning aroundits axis, then there will be many catastrophes. The fact is that under the layer of the earth's crust there is an extensive layer of magma, which, in turn, when the Earth stops, does not immediately stop its movement. The magma layer will continue to move for some time, and this will cause damage to the earth's crust, a powerful pressure on it, which will cause earthquakes and volcanic eruptions. In addition, in the atmosphere there will be a huge force of wind, which will destroy everything in its path.

In the case of a slow stopping of the Earth's motion around its axis, there will be a redistribution of land and the World Ocean. The continents will aspire to the equator, and two oceans - the north and the south - are formed.

If the Earth stops its movement around the Sun,which is also difficult to imagine, it will descend from orbit and rush towards the Sun. The solar wind will destroy the atmosphere of the planet and dry all the water of the Earth, then our planet will go to the side of the giant planets, which, perhaps, just "tear" it into pieces. In general, having descended from the orbit, the Earth will lead to confusion in the entire solar system, and other planets will also descend from their orbits.

But do not be scared. Such scenarios are unlikely or even completely impossible, in the near future, for sure, therefore this information is presented exclusively in a hypothetical context.
