2. During the day, the Sun appears to move across the sky.

13. But the Sun doesn’t move. It’s actually the Earth that moves. It spins on its axis.

14. The axis is an imaginary line that runs through the middle of the Earth from the North Pole to the South Pole. Earth’s axis

15. As you can see the Earth is on a slight angle to the Sun. Earth’s axis
