Earth's Rotation Day

Earth’s Rotation Day takes place on 8th January each year.

Do pupils know that the Earth rotates once every 24 hours?

This presentation looks at whether we are likely to experience a 25 hour day during our lifetimes, given that the rotation of the Earth is gradually slowing. Research has looked at Earth’s rotation over long periods of time so although occasionally the Earth’s rotation speeds up, the pattern over many years is that it is very gradually slowing down.
