What Happen if the Earth stopped spinning?

Well, it kind of is.

The rotation of the earth is gradually slowing down.

And by gradually, we mean.. the length of a day currently increases by about 1.8 milliseconds every century.

So, not really much to worry about there.

But what if it…. just… stopped?

Ok, the probability has been described by scientists as practically zero, but let’ not let that stop us from learning.

What happens?

The earth currently spins at 1770 km/h (1100mph) at the equator, as it orbits the sun.

If that just stopped instantly, it would be... chaos.

Anything on land that was not attached to bedrock, would go flying.

That would mean, rocks, soil, trees, buildings, animals, people would be swept away.

This would also include the oceans, which would be forced sideways, at terrifying speed.

Tsunamis would form.. so high you couldn’t see the top.

Just a gigantic wall of water racing at nearly 2000 km/h.

All of that would be catastrophic.

But wait, there’s more.

Deadly storms

The Earth may stop suddenly, but the atmosphere would continue to spin, which would cause winds and storms travelling at the speed of an atomic blast.

Ok, so that’s what would instantly happen.

If anyone happens to survive those catastrophes, things are about to get a little more interesting.

The current spin of the earth means there’s a bulge of water at the equator, caused by a centrifugal force

If the earth stops spinning, the bulge would flatten, and the water would spread out towards each pole, where gravity is strongest, filling up the Arctic and southern ocean.

That would leave this mega continent, wrapped around the equator of the planet.

In the north, Canada’s gone, as well as the north of Asia and Europe.

Spain, however, would mostly stay above water. Ole!

Down south, the Southern Ocean would start on a line roughly through Canberra, and would see Australia join New Guinea and Indonesia.

Time change

Right, so on the new, still Earth, one day would cease being 24 hours long.

And instead, be 365 days long.

Half of the planet would be locked, facing the scorching heat of the sun, in permanent daytime.

While the other half would be in the permanent, freezing, darkness of nighttime.

The only theoretically habitable part of Earth would be a tiny, twilight strip of land between the two halves.

The poor people who are making their home in the new, tiny strip of land are about to face even more trouble.

Deadly rays

Over time, the lack of earth’s movement would mean that Earth’s protective magnetic field would decay and eventually disappear.

Soon, our atmosphere would disappear as well.

Which then leaves us exposed... to deadly cosmic rays with practically no chance of survival.

Unless we move deep underground, which would pose its own set of challenges.

Look this is all pretty grim, but don’t stress.

Scientists say that this is not going to happen for at least a billion years.

So, we don’t have to worry, as we won’t be around anymore.

Most of us, anyway (Elon Musk and Keith Richards excluded)

Any way you look at it, it spells disaster.

Have you ever wondered what would happen if the Earth stopped spinning?  You can probably guess that it would not result in anything good, in fact, it would be disastrous.  If the Earth stopped spinning suddenly, most people on Earth would die.  If the Earth slowed down gradually, it would be absolutely devastating, but there is a chance some people could survive.  Here is what would happen.

If Earth Suddenly Stopped Spinning

Our atmosphere is rotating at the same rate Earth is spinning: approximately 1050 miles per hour at the equator, with the speed decreasing the further north or south you go from the equator.  The rotation is effectively zero at the north and south pole.

ALSO SEE: What Would Happen if the Sun Disappeared?

If the Earth suddenly stopped rotating, the atmosphere would still continue moving at 1050 miles per hour, and anything not attached to bedrock would be ripped off the surface of the planet.  This includes rocks, trees, buildings, people — all thrown sideways at a speed of 1050 mph (at the equator).  Could you imagine the oceans being pushed inland with that speed?  Oceans would travel approximately 17 miles (28 kilometers) inland in just 60 seconds.  Yikes.  If you are undergound far enough, such as a subway, or at either pole, you might be okay.

If Earth Gradually Stopped Spinning

You may be thinking that, if Earth gradually stops spinning, we won’t be flung around like rag dolls and everything will be okay.  Wrong!  It would be a disaster.

Oceans

Our Earth is not a sphere; it is bulbous, meaning it bulges at the equator (Earth is 26 miles larger around the equator than it is from pole to pole), all thanks to its spinning motion.  If the Earth gradually slowed, the bulging water from the oceans would begin to move away from the equator towards the poles.  Once Earth stopped spinning completely, leaving it as a sphere, the oceans would flood most of Earth leaving one giant megacontinent around the middle of the planet.

Atmosphere

The atmosphere rotates in sync with the Earth, however with Earth’s rotation slowing, the atmosphere begins to follow the flow of the oceans toward the poles.  This flow would eventually lead to air being thicker at the poles and thinner at the equator.  There would exist only four spots around the mid-latitudes where humans could survive.

Geological Disturbances

Earth is comprised of three main layers — the core, the mantle and the crust.  Since each layer is composed of different material, as the Earth’s rotation slows, each layer will slow at a different rate, creating massive friction between the layers.  This friction would result in earthquakes where there had never been earthquakes before and enhanced volcanism, especially on the ocean floor.  Once earth stopped spinning, the geological disturbances would decrease.

Solar Radiation

Scientists believe that Earth’s magnetic field is formed because of Earth’s rotation and the composition of its core — metallic iron.  If the Earth stopped spinning, the magnetic field would disappear leaving us unprotected against the Sun’s harmful ultraviolet radiation and deadly solarwinds.

Length of Day

The length of a year doesn’t change since Earth still rotates around the sun, however if Earth ceased to spin, each day and night would last six months.  Could you imagine?  This could result in extreme temperatures of 135 and -67 degrees Fahrenheit during the day and night respectively.

Weather

If Earth stopped spinning, the atmosphere would also settle and with it the weather.  The weather would become extremely predictable, as it would be controlled only by the sun.  It would result in massive storms on the sunny side of the planet.

The Moon

Currently, the rotation of Earth is faster than the moon, which results in the moon slowly moving away from Earth.  If the rotation stops, the moon will start to move towards Earth, and it would eventually cause Earth to start rotating again.  Unfortunately, the moon would continue to move closer to the Earth until it either collides with it or Earth’s gravity breaks the moon apart.

Although most humans would not survive if the Earth stopped spinning, some people would.  Many animals would go extinct, but others would flourish, especially cold water ocean life.

It turns out that Earth’s rotation is, in fact, going to stop spinning one day, but not for billions and billions of years.  So don’t worry about it!
