What is the effect of the Earth's rotation on the apparent movement of stars?

The apparent movement of stars in the night sky is largely a result of the Earth's rotation. As the Earth spins on its axis from west to east, it creates the illusion of stars moving across the sky. This movement is observed as stars appearing to rise in the east and set in the west. This pattern is consistent due to the spherical shape of the Earth and its rotational direction.

The rotation causes observers located on the surface to see different portions of the sky at different times throughout the night. Consequently, this motion mimics the rising and setting of celestial bodies and is a fundamental aspect of our observational experience of the night sky.

The other options do not accurately represent this phenomenon: stars do not rotate around the poles in a way that reflects their appearance to observers, they do not remain stationary, and they do not rise in the west; these options misunderstand the relationship between Earth's rotation and the observed movement of stars.
