The earth tilting on its axis causes

• day and night
• 365.25
• 24 hours
• seasons

Which movement causes day and night?

• revolution
• rotation
• radius
• momentum

How much time does it take the Earth to complete one revolution?

Imaginary line through the center of the earth (from the north pole to south pole)

• axis
• orbit
• pole
• tilt

The path around the sun

• orbit
• rotation
• season
• equinox

Why is summer warmer than winter?

• The hemisphere experiencing summer is tilted more directly toward the sun
• The entire planet is closer to the sun during summer
• The sun radiates more energy during the summer
• The earth spins slower on its axis during the summer

The sun appears to move across the sky each day.  What causes this?

• the spinning of the Earth's axis
• The path of the sun around the Earth
• the production the nuclear energy around the sun
• the tilt of the Earth on its axis
