Earth's Rotation

About how much time does it take the Earth to complete one rotation?

• 24 hours

• 7 days

• 28 days

• 1 year

The Sun appears to move across the sky due to the -

• rotation of the Earth

• gravity of the Moon

• large size of the Sun

• movement of the tides

The change from day time to night time, and back again, is caused by –

• the position of the Moon.

• the movement of the tides.

• the brightness of the Sun.

• the rotation of the Earth.

The diagram shows the Earth rotating as it receives light from the Sun.

Which location on the Earth is about to experience sunrise?

• A

• B

• C

• D

In the morning, the Sun is low in the sky and by noon the Sun is much higher in the sky because -

• the Sun has increased its temperature.

• Earth has rotated on its axis.

• the Sun has turned to face Earth.

• the Earth has moved closer to the Sun.

About how long does it take for one rotation of Earth?

• 12 hours

• 18 hours

• 24 hours

• 48 hours

Which of the following takes about one day?

• One rotation of the Earth on its axis.

• One revolution of the Moon around Earth.

• One orbit of the Earth around the Sun.

• One rotation of the clouds across the sky.

The Sun appears to move across the sky because -

• the Sun orbits around Earth.

• Earth rotates on its axis.

• the Moon revolves around Earth.

• the Sun gets smaller in the evening.

Earth rotates on its axis giving us night and day. Earth’s axis is -

• the path of the Earth as it orbits the Sun.

• a line between light and dark parts of Earth.

• a band of clouds around the center of Earth.

• an imaginary line through the poles of Earth.

A student modeled the cause of day and night on Earth using a lamp and a baseball.

If one second equals one hour, how should the student model one day/night cycle on Earth?

• Move the baseball around the lamp in 24 seconds.

• Turn the lamp off and on for 24 hours.

• Spin the baseball 24 times in one hour.

• Rotate the baseball one time in 24 seconds.
