Our planet's rotation goes almost unnoticed in our day-to-day lives, but what would happen if it stopped spinning altogether? Or span in the opposite direction?

Earth rotates at around 1,670 km/h, but how important is this rotation to our lives? If this stopped suddenly the effects would be catastrophic, as Maddie Moate from Earth Unplugged explains. We and everything else not attached to the planet would be thrown sideways. Oceans would maintain momentum and a giant tsunami would spread water inland within a minute.

But what would happen if the planet gradually came to a standstill? And what would happen if Earth started spinning in the opposite direction. Watch the video to find out.
