Question

Quizplus · Accepted Answer

The subsolar point is at the Tropic of Capricorn when all latitudes above 66.5ºN experience 24 hours of darkness, which occurs during the December solstice. This is when the Southern Hemisphere is tilted towards the Sun, resulting in the longest day in the Southern Hemisphere and the longest night in the Northern Hemisphere.
