The Earth rotates on its axis, which is why we experience day and night. The Earth spins from west to east, making the sun appear to move from east to west across the sky.

Here's a breakdown:

* Earth's Rotation: The Earth spins on its axis, completing one rotation roughly every 24 hours.

* Apparent Sun Movement: As the Earth rotates, the sun appears to move across the sky from east to west. This is because our perspective changes as we rotate with the Earth.

* Actual Sun Position: The sun remains stationary, while the Earth rotates around it.
