Which of the following is caused by Earth’s rotation?

• the seasons
• day and night
• the actual movement of the sun
• the moon’s revolution around Earth

What causes Earth’s day and night cycle?

• Earth’s revolution around the sun approximately once every year
• Earth’s rotation around the sun approximately once every year
• Earth’s rotation on its axis approximately once every 24 hours
• Earth’s revolution on its axis approximately once every 24 hours

A student creates a model of Earth’s path around the sun. Which word should she use to indicate that Earth “goes around” the sun?

• rotates
• revolves
• moves clockwise
• moves counterclockwise

In a drawing of Earth’s path around the sun, what would be the correct label for that path?

• rotation
• gravity
• orbit
• axis

What is Earth’s axis?

• the imaginary line that goes through Earth from pole to pole
• the imaginary line that separates day from night on Earth
• the imaginary line that separates warm weather from cold weather on Earth
• the imaginary line that goes through Earth from the continent of Asia to the Americas

A student did an experiment with a globe and a lamp. He wanted to see what would happen if Earth’s axis of rotation always pointed toward the sun. If he did the experiment correctly, what did he find?

• Earth would stop rotating to cause night and day.
• Each pole would be in darkness for about half the year.
• Earth’s entire northern half would always be in darkness and the southern half always in light.
• One pole would always be in darkness, and the other always in light.

From which direction does the sun appear to rise and in which direction does it set as Earth rotates?

• north to south
• west to east
• east to west
• south to north

When it is midday in Texas, it is light outside. What causes it to get dark at night?

• the rotation of Earth on its axis
• the gravitational pull of the sun
• the revolution of Earth around the sun
• the revolution of the moon around Earth

Earth orbits the sun, yet the sun appears to move across Earth’s sky, rising in the east and setting in the west. What causes this apparent movement of the sun?

• Earth’s revolution on its axis approximately every 24 hours
• Earth’s rotation around the sun approximately every year
• Earth’s rotation on its axis approximately every 24 hours
• Earth’s revolution around the sun approximately every year

Kate wants to build a model showing what causes the day and night cycle on Earth. What should she demonstrate in her model?

• Earth’s revolution around the sun approximately once every year
• Earth’s rotation around the sun approximately once every year
• Earth’s rotation on its axis approximately once every 24 hours
• Earth’s revolution on its axis approximately once every 24 hours
