This is a great question that often leads to confusion! Here's the breakdown:

* The Sun appears to move across the sky, but that's an illusion caused by the Earth rotating on its axis. The Sun itself is actually stationary relative to the Earth.

* Clouds move due to wind. The wind currents in the atmosphere push the clouds along.

So, in reality, the Sun doesn't move, and clouds do move.
