On Earth’s surface, when it is summer at point A, it is winter at point B. Which best explains why it is winter at point B?

• Point B is closer to a pole than point A, so it is always farther from the Sun.

• The elevation of point B is greater than that of point A, so it has less atmosphere to absorb sunlight.

• Point B is located in an area where ocean and atmospheric currents tend to circulate heat away

  from it.

• Point B is located in the Southern Hemisphere, so Earth’s axial tilt causes it to receive less

  sunlight than point A.
