What happens if the earth stops?


As we know, everything in our world rotates. The Earth is around its axis and around the Sun, and it revolves around its axis and at the same time around the center of the Galaxy, which also moves around the center of the local accumulation of galaxies. We are unable to stop it. But let’s just imagine that the Earth stopped his rotation around the axis. What happens to life on earth?

In nature there are planets that seem to not rotate. These planets are always turned one side to their star. This is due to the fact that the gravitational interaction (tidal forces) between the planets and their stars can gradually slow down the rotation speed of the planet until the period of rotation around its axis coincides with the orbital period. For the very reason, the moon is always turned to one side to us.

The same situation is also on many exoplanets, especially on those who are very close to their stars, where the tidal effect is stronger. As a result, one side is extremely frozen, and the other is riveted.

The rotation of our planet slows down by about 1.7 milliseconds per century. It is so small that this slowdown is absolutely unnoticed and unlikely to stop completely all the time that the solar system remains. But let’s imagine that the land stopped sharply.

If the Earth instantly ceased to rotate, it would be a catastrophe. We do not feel this, but at the equator, the speed of rotation of the Earth reaches about 1600 km / h. If the land stops sharply, all objects on the inertia will fly to the east. People, houses, trees and everything else will continue their movement at hundreds of kilometers per hour (1600 km / h at the equator, the closer to the poles, the less speed). What happens when you meet with the nearest hill at such a speed I think to everyone understand. In addition, the atmosphere rotating along with the Earth will clean up almost all of its surface with the strongest hurricane wind, the exception will be only polar regions that rotated much slower.

If the earth will stop gradually, the consequences will still be disastrous, although they will unfold slower. Without 24-hour days, we are accustomed to all animals, all biological rhythms would be shot down, which would lead to the death of many species of animals and plants. Over time, the climate on Earth will change, because the day will become equal to the year and the surface will freeze, then it will be split every year. Only a few microorganisms and the inhabitants of the depths of the ocean will be able to survive in such conditions. Some scientists believe that the end of our magnetic field would also come, which protects the planet from cosmic rays, however, it is believed that the rotation of the planet is not so significant in the formation of a magnetic field.
