Because each hemisphere faces a different part of space, and Earth’s curvature blocks the view of some constellations from the opposite side.

A student claims that stars move because Earth revolves around the Sun. Another student disagrees and says they move because Earth rotates.
Who is correct, and how could you design an observation to prove it?
Both are partly correct, but they describe different patterns:
Rotation causes stars to move across the sky each night.
Revolution changes which constellations are seen during the year.
