The movement of the Earth and the Moon

The movement of the Earth

The Earth is constantly spinning on its axis. The spinning motion of the Earth on its axis is called rotation. The axis is an imaginary line through the Earth linking the North and the South poles. The Earth takes 24 hours to complete a full rotation on its axis.




The Earth rotates from the west to the east. So, the Sun rises in the east and sets in the west. As the Earth spins about its own axis, it also moves around the Sun. The Earth moves around the Sun in a fixed path known as the orbit.

It takes the Earth one year to make a complete journey around the Sun.
