What would happen if the Moon disappears
Source:Ask yourself the question: what will happen to Earth if the sky will disappear the Moon? Is it even possible? What impact will expect our planet? Many will remember the influence of the moon on the tides. In fact, the influence of the natural satellite of our planet is much more serious.
How was the Moon?
According to the most popular to the researchers, shortly after the formation of Earth (about 4.5 billion years), it hit on a tangent kind of celestial body the size of a planet. As a result of the impact part of the substance of this object and part of earth's mantle was thrown into orbit. Of debris eventually formed the Moon, starting to turn in its orbit with a radius of about 60 000 km.
When can the Moon fall to Earth?
Since its formation the Moon was annually away from our planet. Gradually, the speed of separation has increased and now stands at 3.8 centimeters per year. If so, how can the Moon fall to Earth? You will not believe, but among scientists there is an opinion that such a scenario is possible. Fortunately, it will happen very soon.

A Couple of years ago, the American planetary scientist Jason Barnes said that the Moon could fall to Earth in 65 billion years. The opinion he explained that by the time the rotation speed of the earth's axis very slow. According to various estimates, this could occur in about 50 billion years, when the heavenly bodies will be in the mutual spin-orbit resonance. As a result, the Moon will not move away and be attracted to our planet. Interestingly, this will be able to help our Sun. How?
In About 5 billion years in our Sun runs out of hydrogen, which is the energy source of stars. Our star will move to a new stage of its evolution, becoming a so-called red giant. The luminosity of the star will increase the pressure inside her increase, and the outer shell begins to expand. Powerful emission from the atmosphere of a red giant can quickly change the orbit of the moon, forcing the latter to begin to move slowly to the Ground. But, will there be a clash?
If you think that we are talking about the clash head-on like in the video above, then no. It will not. When the convergence distance between the Moon and Earth will be about 18,000 km (), the tidal interaction of the planet with the satellite will break the last on a huge pile of rubble. Part of them forms around the Earth a system of rings. Through time, most of the rings will begin to break down, and the remainder to collide with Earth.
In any case, by this point life on Earth will be already impossible. Like any other planet in the Solar system. Even when turning the Sun into a red giant the atmosphere of the star expands so that you can reach the current borders of the Earth's orbit. Of course, this will be completely destroyed the two closest planet from the Sun – mercury and .
Let's get out of this chain of events would exclude the presence of a red giant. In this case, it will affect the Earth the disappearance of the moon?
would Not have solar and lunar eclipses
Without the moon there would be eclipses – would not object capable of at least partially obscures the solar disk. You can also add that the night will become darker.
Change of tidal power
The moon and the Sun are responsible for tides. The reason for these processes is the heterogeneity of the gravitational field of these heavenly bodies, which is reflected in the fact that in different parts of the earth for the same mass of water have different gravitational forces. The disappearance of the moon would cause the tides significantly weakened, as the only celestial body that affect the world's oceans, will be the Sun.
The Tidal forces of the moon influence on the earth's crust. If the Moon will disappear, the main change is that within a few stops of tectonic and volcanic activity.
will the axis of rotation of the Earth?
The moon's Influence on the stabilization of the Earth's rotation axis is exaggerated. Although this influence is definitely the place. Previously it was thought that if the Moon disappeared, the axial rotation of the Earth would be totally chaotic. This in particular would result in unpredictable change of seasons.
How is the disappearance of the moon affect animals?
The disappearance of the moon will also strongly affect many species of animals and plants. First and foremost, the consequences will impact on those sea creatures, whose life cycle is somehow tied to the tides.
