• Yes, because the Earth is moving.

• Yes, but only internally due to biological processes.

• Only if you're on a vehicle or walking.

Why can't you feel Earth's movement?

• Because you're moving at the same speed and direction as Earth.

• Because Earth moves too slowly.

• Because of your tiny size compared to Earth's size.

• Due to the gravitational pull of the sun.

What does the merry-go-round analogy explain?

• The orbit of the moon around Earth.

• The rotation of the Earth around the sun.

• The gravitational forces acting on Earth.

• How objects in the sky appear to move due to Earth's rotation.

What is an axis?

• A point in space that Earth orbits around.

• A type of force that acts upon Earth.

• An imaginary line through the center of an object that is a fixed point of reference.

• The path that Earth takes as it orbits the sun.

How often does Earth make one full rotation around its axis?

• Every 24 hours

• Every 12 hours

• Once a week

• Once a month

What causes the apparent movement of the sun and stars across the sky?

• The actual movement of the sun and stars.

• The rotation of the sun around Earth.

• Earth's rotation on its axis.

• The movement of the moon.

In which direction does Earth spin?

• From east to west

• From west to east

• From north to south

• From south to north

What evidence can you see in a single day or night of Earth's rotation?

• The change in weather patterns.

• The phases of the moon.

• The movement of clouds.

• The appearance and movement of the sun and stars.

Why do constellations appear to move across the sky every night?

• Due to the rotation of the Milky Way galaxy.

• Because of the Earth's rotation on its axis.

• Because the constellations themselves are moving.

• Because Earth is moving in its orbit around the sun.

Why are different constellations visible in different seasons?

• Because Earth orbits the sun, changing our view of space.

• Because constellations move closer or farther from Earth.

• Due to changes in the Earth's atmosphere.

• Because of the Earth's tilt on its axis.
