Why do the stars and the constellations in the sky appear to change positions throughout the night and throughout the year? (1 point)
• The Earth's tilt changes its position relative to the stars and constellations as the Earth rotates and orbits.
• The stars and constellation have tilted and are also moving in space.
• The Earth's tilt changes its position relative to the stars and constellations only because the Earth rotates around its axis.
• The location angle of the Earth's tilt relative to the stars and constellations remains the same throughout the year.
The Earth's tilt changes its position relative to the stars and constellations as the Earth rotates and orbits.
The correct answer is: The Earth's tilt changes its position relative to the stars and constellations as the Earth rotates and orbits.
Explanation:
Throughout the night and throughout the year, the stars and constellations appear to change positions in the sky due to the rotation and orbit of the Earth. The Earth rotates on its axis once every 24 hours, causing objects in the sky to appear to move from east to west. This rotation gives the illusion that the stars are moving across the sky.
Additionally, the Earth's orbit around the Sun causes a yearly change in our perspective of the stars and constellations. As the Earth moves along its elliptical orbit, the direction of our view of the night sky changes. This leads to different constellations being visible at different times of the year.
The Earth's tilt also plays a role in the changing positions of the stars and constellations. The Earth's axis is tilted relative to its orbit around the Sun. As a result, the angle of the Earth's tilt changes as the Earth revolves around the Sun. This changes our perspective of the stars and constellations over the course of the year.
In summary, the apparent change in positions of the stars and constellations is a combination of the Earth's rotation on its axis, its orbit around the Sun, and the tilt of its axis.
The Earth's tilt changes its position relative to the stars and constellations as the Earth rotates and orbits.
