Why are summer days longer than winter days on Earth? (SC.8.E.5.9)

• During the summer, Earth’s rotational axis is parallel to the Sun’s rotational axis.

• During the summer, Earth is at the point in its orbit when it is closest to the Sun.

• The region of Earth experiencing summer rotates past the Sun more slowly than the region experiencing winter.

• The region of Earth experiencing summer is tilted toward the Sun while the region experiencing winter is tilted away from the Sun.
