The consequence of the sudden stop of rotation is to tear, heavy rectification, accumulation

The earth rotates as stable as a gyroscope. So what would happen if the earth suddenly stopped rotating?
If you stop it from the turn, the angular motion of each object on the earth will tear the surface, causing a very, very bad day.
"This is just an imaginary experiment," said James Jinbelman. He is a senior honorary geological scientist at the Smithsonan National Aerospace Museum in Washington Special Economic Zone. "No natural forces can stop the earth. This is also part of the reason that this planet has been rotating since the formation, which is also very impressive. "
Rotate the earth.
Jin Bellman pointed out that the earth's winding axis completely rotated for a week. It cost 23 hours, 56 minutes, 4.09053 seconds, and converted to the road. The land movement speed was 1,100 miles per hour, that is, 1770 kilometers per hour, and the polar speed was 0. If the earth stops suddenly, the air that gives the air along the equator, the angular driving volume of water and even rocks will continue to exercise at a speed of 1100 miles per hour. Such games will be scrued and tear the surface, and the fragments are sent to the top of the atmosphere or even the outer space.
But what is angular momentum?
Let's take a step back. Linear momentum is the product of the quality and speed (direction and rate) of an object. A sudden passenger on a driving car will continue to move forward due to linear momentum.
Corner volume is a rotation form of linear momentum. The angular volume is the multiplier of the inertia (rotating power required for rotation quality) and the charging of the angle speed. When the four -point guard raised his football into the air and throw it into an outer person, he gave the football angle momentum.
"One of the basic theorems of physics is to keep the angle and conservation." Jin Belman told Live Science, "If an object is rotating, you must apply the same size in the opposite direction to make it allow Stop rotating. "
But if the earth stops rotating, it will not be lost.
Reorganize, reorganize, accumulate.
Jin Bellman said that when the earth and its residuals continue to rotate around the sun, the fragments that fall off from its surface will also rotate again. In the end, the earth will be unexpectedly pulled back to the fragmented aura.
"Newton used classic mechanics to help us discover: constantly accumulating and close fragments will release their own energy to heat the object," Jin Bellman said.
"You can imagine it as a meteor across the sky. In the end, the wreckage of the outermost and outer space of the atmosphere will be attracted to the surface under the action of geographical gravity and releases energy when impact. Make the crustal liquefied into a melting 'rock ocean' ", Jin Bellman said," The fragments generated by the final impact were re -absorbed into this melting ocean through the process of absorbing the accumulation "
Jin Bellman said that this rapid and devastating change can also evaporate most of the water on the surface of the earth. Most of the evaporation water will be lost, but there may also be absorbed into the newly formed ore, such as olives.
In the end, not all fragments can be re -absorbed by the accumulation. The fragments of the earth will be swept by the gravity of the moon, bombard them, and form countless meteorites on its surface.
related information
Earth rotation is a solid earth rotating around its own axis, and the direction is from west to east; so the earth rotates from west to east. From a bird's -eye view of the Arctic of the sky, the earth rotation is rotating counterclockwise; from the point of view of the Antarctic point, it is rotated clockwise.
The cycle of the Earth's rotation is a star day, and its current value is 23:56 minutes. However, in recent years, the earth's rotation cycle has increased slowly (that is, slowly decreased speed), which requires adjustments to global timers. For example, the global watch on December 31, 2005 will be uniformly added for a second. Such adjustments are called leap seconds.
