Temperatures in the southern hemisphere show a smaller annual range than the northern because

  • A.its atmosphere is a good deal thinner
  • B.the southern hemisphere is mostly ocean
  • C.it receives a good deal less sunlight overall
  • D.it is closer to the Sun in its summer

Answer: B

Correct answer: the southern hemisphere is mostly ocean

Land covers about two fifths of the northern hemisphere and only a fifth of the southern, so the south is dominated by water, whose great heat capacity damps the seasonal swing. It is the same continentality effect that separates a coastal from an inland station, applied at hemispheric scale.
