• The angle at which sunlight reaches the Northern Hemisphere changes.

• The angle that Earth is tilted on its axis changes.

• The amount of energy that is produced by the sun changes.

• Mars takes almost twice as much time as Earth to orbit the sun once.

• Mars takes more than half as much time as Earth to rotate once on

  its axis.

• Mars takes almost twice as much time as Earth to rotate once on its axis.

When it is winter in the Northern Hemisphere, it is summer in the Southern Hemisphere. Which reasoning best supports this claim?

• When the Northern Hemisphere is tilted away from the sun, the

  Southern Hemisphere is tilted toward the sun.

• When the Northern Hemisphere is tilted toward the sun, the

  Southern Hemisphere is tilted away from the sun.

• When the Northern Hemisphere is closer to the sun than the

  Southern Hemisphere is, the Southern Hemisphere is relatively far from the sun.

• When the Northern Hemisphere is farther from the sun than the

  Southern Hemisphere is, the Southern Hemisphere is relatively close to the sun.
