Question

Lauren went outside with her telescope to study the constellations. While observing the night sky, she notices that the big dipper appears to have moved during the night. What causes this constellation to appear to be moving?

A) Stars revolve around the Earth all throughout the day.
B) Constellations are moving across the sky as hours pass.
C) The big dipper appears to move because of the Earth's rotation.
D) The constellation appears to have moved because Lauren's position has changed.

Answer 1

Answer: C

Explanation: C is the most logical. D is technically true, but this answer is talking about her position on Earth, not in space. As Earth rotates and revolves, constellations will move throughout the year in a pattern.

Hope this helps :)
