What would happen if the Earth stopped rotating?

In the 1951 film, The Day Earth Lived Again, an alien named Klatu and his robot friend Gort simultaneously disable nearly all electronic equipment on Earth using their advanced alien technology.

Cars, factories, television equipment, and many other things ceased to function, and the planet settled into a kind of eerie stillness. But imagine an alien possessing an even more powerful tool that could stop the Earth from spinning.

The consequences would be far more devastating. We may not realize it, but the rotation of our planet underlies some of the most fundamental processes that occur on Earth. In fact, if Earth were a stationary planet, we humans probably wouldn't be here.

If the Earth were to stop spinning instantly, it would be extremely catastrophic for most of the planet's surface. Although we don't feel it on a daily basis, we all move with our rotating planet.

At the Equator, this speed is about 1600 km/h. If the planet were to stop suddenly, everything on it would also fly due to inertia towards the east. Imagine a moment people, houses, trees, stones and many other things moving at a speed of hundreds of kilometers per hour.

After that, high-velocity winds, at a speed as fast as the planet's rotation, will sweep away everything above the Earth's surface. If the slowdown were to occur more gradually, the effects would still be dramatic, but would develop over a longer period of time.

The first thing we might notice would be the fact that the Sun no longer travels across the sky during a day. The apparent motion of the Sun comes from the rotation of the Earth. So if the planet were stationary, this would make a single day last half a year (although we could expect some very long sunsets).

Without the 24-hour days we're used to, our biological circadian rhythms would get out of control. The rhythmic cellular processes that tell our bodies when to sleep and when to wake depend in part on regular changes in sunlight to function. Many creatures on Earth, from bees to trees, rely on circadian rhythms to carry out their normal life functions. Changing these cycles can use normal behavior patterns.

Atmospheric patterns on Earth are also related to the rotation of the planet. If the planet were to stop rotating, it would also greatly change the way the air currents move (since the 1,600 km/h winds would disappear).

The wind patterns we see today play an important role in driving precipitation and temperatures across the globe. Any change in air currents can cause deserts to be created where forests are currently located, or for example frozen tundra to become habitable.

We are already seeing something similar, albeit on a much smaller scale, as climate change is significantly altering global weather patterns. And the consequences can be catastrophic for organisms that depend on specific environments.

An Earth without rotation around its axis and around the Sun would also mean the end of hurricanes. Storms of this type are created by the 'Coriolis' forces, which are created precisely by the rotation of our planet.

Winds drawn into the low pressure area of ​​a growing storm rotate clockwise in the Northern Hemisphere, and counterclockwise in the Southern Hemisphere, causing the typical spirals and central "eye" of the storm. that define a hurricane. This process is one reason storms can grow so powerful — so cutting them off could be one of the rare benefits of stopping the planet from spinning.

But a stationary planet would also mean the end of our magnetic field. Although scientists are still unclear on the exact mechanisms, it is thought that the magnetic field is created by the movements of Earth's liquid metal core. Scientists call this a dynamo, and the end result is a network of invisible magnetic field lines that arc around the planet.

The effects of losing this field would be far worse than simply not being able to orientate via compass. This is because the Earth's magnetic field protects us from cosmic rays and electromagnetic storms from the Sun.
