why it's spinning.

But what would happen if the Earth suddenly stopped rotating?

Keep in mind, this is totally impossible.

Still, I find topics like this super interesting to think about.

If the Earth actually stopped rotating instantly, it would be very *very* bad for everything

on the surface of the planet.

Consider this. If you're standing on the equator, you're traveling at 465 meters/second from

West to East.

If the Earth put on the brakes, your momentum would keep you flying at the same speed until

*friction* slowed you down.

Imagine the jumbled forests, oceans, buildings and unfortunate animals after that event - it

would be carnage.

The atmosphere is also turning at 465 meters/second with us. If everything suddenly stopped, it

would be like a simultaneous hurricane of epic proportions on almost every part of the

planet.

The closer you get to the poles, however, the less damage it would cause.

If you were standing on the North Pole, you'd hardly feel it.

Let's imagine the Earth slowed down more gradually, taking a few days to come to a halt that didn't

tear the landscape into fine mist of dirt, seawater and a variety of organic material.

The stars would hang fixed in the sky; only the planets would move around, continuing

their paths around the Sun.

A day on Earth would now last 365 days. In other words, it would take a full year for

Earth to fully orbit the Sun, bringing it back to the same location in the sky. Each

year would include one long day, and then one long night. You can imagine how that would

be devastating to plants and animals.

We get a hint of this at the poles, where you can experience weeks of permanent night

and then weeks of permanent day. But imagine 6 months of night, followed by 6 months of

day.

The planet's tilt gives us our seasons. As we define the Earth's tilt as its rotation

in relation to the Sun. A stationary planet would effectively have no tilt at all.

Without that tilt, there'd be no axis, and no seasons. Although we would still have North

and South poles.

Because of its rotation, turning once every day, the Earth is actually a flattened ball,

or if you prefer, an oblate spheroid.

Without that rotation the Earth would become a perfect sphere. This sounds interesting

and probably harmless, but it's actually a *big* problem.

Because of the Earth's bulge in the middle, the oceans are held out at the equator by

8 km. On perfect sphere Earth, the world's oceans would redistribute, flooding many regions

of the planet with an immense volume of water.

We'd end up with a single continent around the middle of the planet, with oceans surrounding

the north and south poles.

Let's assume that if the Earth stopped turning, the Earth's core would stop rotating within

it as well.

This natural dynamo generates the magnetic field that surrounds our planet and protects

life from radiation from space.

Whatever life still alive would be irradiated from the Sun and cosmic rays if it didn't

live underground.

So, if the Earth suddenly stopped turning, it would be very bad, even catastrophically

bad.

Fortunately, it's completely impossible for this to happen.

Thanks for watching.
