The magnetic field that protects the Earth from dangerous cosmic radiation will disappear
The magnetic field is basically formed by the process of the outer core (mostly made of iron) and the rotation of the planet. Astronomer Sten Odenwald predicted that if the Earth stopped rotating on its axis, the magnetic field would also disappear. Charged particles from the sun will destroy all living things on Earth.

The moon will slowly fall to Earth
Professor Vaughan Pratt from Stanford University said the Moon will also gradually slow down and the distance from Earth will decrease. Over time, it will probably fall to our planet.

All objects will fly to the East at very high speeds according to their own momentum
We won’t be able to feel the enormous speed at which the Earth is rotating around its axis. NASA astronomer Sten Odenwald said that if the Earth stopped spinning on its axis, everything on the Earth’s surface would be ripped from the ground and fly to the East at a very fast speed and would eventually fall back again. . At the equator, the speed will be greatest (about 1610 km/h) and near the poles it will reach 1288 km/h.

If humans survived, we would be on the border between hot and cold, day and night
Humanity will only be able to adapt to the new conditions at the border of day and night. Humans will have to live underground and only come out in protective clothing from radiation.

Huge tsunamis will appear
The force of momentum will cause the water in the seas and oceans to move forming powerful tsunamis that will move eastward and wipe out coastal cities from the Earth’s surface.

All the water on Earth will accumulate into 2 oceans and a new continent will form
Water gathers at the equator now due to centrifugal force. If the Earth stops rotating on its axis, the masses of land and water will redistribute themselves to form two large oceans at both poles. The land above the equator will rise and form a giant new continent that will cover the entire planet through the equator.

The earth will transform from a geoid to a sphere
The geographical shape of the Earth is due to its axial rotation. It is slightly flat on the poles and slightly bulges at the equator (see lecture by Professor Etienne Ghys from ENS de Lyon). If the planet stops, its shape will gradually become spherical.

A hurricane will rise
The atmosphere will continue to move, and the momentum of the atmosphere will cause it to orbit the planet – possibly several times. The initial airflow speed will be huge: more than 1771 km/h. And it is possible that Earth will lose part of its atmosphere.

One hemisphere will be as hot as the desert and the other as cold as Antarctica
If the Earth continues to revolve around the sun, half of it will burn up and always glow with the highest temperature at the equator. The second hemisphere will become a kingdom of eternal darkness and cold like Antarctica. NASA has another version: The Earth will stop rotating on its axis completely and a day lasts 6 months, followed by a night of the same length.

Volcanic eruptions, storms and earthquakes will begin to form
The enormous kinetic force of the Earth and its momentum would shake the planet to the Earth’s core. The results were predictable: massive hurricanes, volcanic eruptions, and earthquakes would destroy everything.
