Question

why do some celestial constellations no longer touch the ecliptic plane? a) the earth rotating has caused the change. b) precession has caused the change. c) the earth revolving has caused the change. d) stars have rotated and changed their positions in the sky.

Explanation:

The precession of the Earth's axis causes a slow change in the orientation of the Earth - sky relationship over time. This results in the positions of the constellations relative to the ecliptic plane changing. Stars themselves do not significantly change their positions in the short - term due to their vast distances and slow proper motions compared to the effect of precession. Earth's rotation and revolution do not cause this specific long - term change in constellation - ecliptic relationships like precession does.

Answer:

B. Precession has caused the change.
