The Sun doesn't move from north to south each day. It appears to move across the sky from east to west every day due to the Earth's rotation.

Here's the breakdown:

* Earth's Rotation: The Earth spins on its axis, completing one rotation roughly every 24 hours. This rotation is what causes the apparent movement of the Sun across the sky.

* East to West: As the Earth spins, it appears that the Sun is rising in the east and setting in the west.

* North-South Movement: The Sun's apparent path across the sky changes throughout the year due to the Earth's tilt on its axis. This tilt causes the Sun's path to shift north in the summer and south in the winter.

So, while the Sun appears to rise in the east and set in the west every day, its daily motion doesn't involve a north-to-south movement. That north-south movement is a seasonal change in the Sun's path across the sky.
