Why do the stars and the constellations in the sky appear to change positions throughout the night and throughout the year?

1.The Earth’s tilt changes its position relative to the stars and constellations only because the Earth rotates around its axis.
2.The location angle of the Earth's tilt relative to the stars and constellations remains the same throughout the year.
3.The Earth’s tilt changes its position relative to the stars and constellations as the Earth rotates and orbits.
4.The stars and constellation have tilted and are also moving in space.

3. The Earth’s tilt changes its position relative to the stars and constellations as the Earth rotates and orbits.

This is because as the Earth rotates on its axis and orbits around the Sun, our perspective of the night sky changes. This causes the stars and constellations to appear in different positions at different times of the night and throughout the year.
