The Earth and Moon in Space

What causes day and night?

• Earth's movement around the sun
• The moon's movement around the Earth
• The tilt of the Earth
• The spinning of Earth around an axis

What evidence do scientists have that Earth spins around an axis?

• The sun looks like it is moving.
• They can see it from outer space.
• The Earth feels like it is moving.
• They do not have any evidence.

Why is a day on Earth 24 hours long?

• That is how long it takes Earth to spin around its axis one time.
• That is how long it takes Earth to travel around the sun one time.
• That is how long it takes the moon to travel around the Earth one time.
• That is how long it takes the sun to travel around the Earth one time.

Why is a year on Earth 365 days?

• because hat is how long it takes Earth to spin around one time
• because hat is how long it takes the Earth to travel around the sun one time
• because there are 12 months in a year
• because that is how long it takes the sun to travel around the Earth one time

How many degrees is Earth's axis tilted?

• 0
• 12.5
• 23.5
• 90

Which part of Earth receives direct sunlight for the entire year?

• North Pole
• South Pole
• Equator
• The entire Earth

What would happen if Earth was not tilted?

• There would be no seasons.
• Every place on Earth would have 12 hours of daylight for the entire year.
• NJ would be the same temperature for the entire year
• All of the above.

What causes seasons?

• Earth getting closer and farther from the sun
• Earth spinning around on its axis
• The Earth's tilt as it travels around the sun
• all of the above

What is an axis?

• 23.5 degrees
• an imaginary line that goes around Earth
• An imaginary line that goes from the North Pole to the South Pole
• the tilt of the Earth

The path an object takes as it moves around another is 

• rotation.
• revolution.
• orbit.
• trail.
