What is the primary reason that the constellations we see in the night sky change throughout the year?

The rotation of the Earth on its axis.

The revolution of the Earth around the Sun.

The movement of the constellations themselves through the galaxy.

The tilt of the Earth's axis, which causes the seasons.

The text uses the analogy of the night sky being a "window." In this analogy, what causes the view out of the window to change from month to month?

The window itself getting bigger or smaller.

The stars moving past the window.

The Earth's orbit around the Sun.

the Earth's revolution around the Sun.

the stars of the Big Dipper moving through space.

the Earth's rotation on its axis.

changes in the Earth's magnetic field.

The Sun orbits the Earth once per year.

The Earth orbits the Sun once per year.

All stars are the same distance from Earth.

The Earth is the center of the galaxy.

The constellation Orion has moved to a different part of the galaxy by summer.

During the summer, Earth's position in its orbit causes Orion to be in the sky during the daytime, where it is obscured by the Sun's bright light.

Earth's daily rotation is slower in the summer, so Orion never rises above the horizon.

Increased humidity and clouds in the summer atmosphere always block the view of that specific constellation.
