Earth - Sun Relationships

What happens when it's spring in the Southern Hemisphere?

• It's fall in the Northern Hemisphere
• It's summer in the Northern Hemisphere
• It's winter in the Northern Hemisphere
• It's spring in the Northern Hemisphere

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

The length of one year is the time it takes

• the moon to complete its phases.

• Earth to complete 12 rotations around its axis

• Earth to complete one revolution around the sun.

• the moon to complete one revolution around the Earth.

It is necessary to add a day to the calendar every four years because

• the axis of Earth is tilted.

• the gravitational pull of the Sun affects Earth's revolution.

• the revolution of Earth is not exactly 365 days.

• the axis of Earth’s orbit is parallel to its orbit

The seasons are caused by Earth’s tilted axis as it travels around the sun. What causes winter in the Southern Hemisphere?

• The North Pole tilts away from the sun

• The equator receives more direct light

• The South Pole tilts away from the sun

• Earth moves further away from the sun

32. Which of the following is a direct result of Earth’s rotation?

• Lunar eclipses

• Winter weather

• Daylight and night

• seasons

What controls the length of a day?

• the amount of time it takes Earth to complete a

  turn on its axis

• the amount of time it takes Earth to complete an

  orbit around the sun

• the amount of time it takes the moon to complete

  an orbit around Earth

• the amount of time it takes the sun to complete

  a turn on its axis
