Question

Why do the constellations seem to move around in the sky? A. Gravity pulls them closer to Earth, and then lets them go. B. The Earth's rotation makes the constellations appear to move. C. People are moving around on the surface of the Earth. D. The sky rotates above us on its axis while the Earth stands still.

Answer 1

The answer is B. the Earth's rotation makes the constellations appear to move.

The Earth is not the center of the universe and its gravity doesn't reach the stars so A and D is wrong. C is wrong since the constellations will move even if people stand still.

Answer 2

The answer is B. we are revolving around the sun and so our view of the ski moves too.
