The equinox

Quizplus · Accepted Answer

The equinox is a moment in time when the subsolar point is exactly at the equator, resulting in 12 hours of daylight and 12 hours of darkness for all locations on Earth. Therefore, option B is the correct choice. Option A is incorrect because the subsolar point is at the tropics during the solstices, not the equinox. Option C is also incorrect because the longest day of the year occurs during the summer solstice, not the equinox. Option D is incorrect because the equinox occurs twice a year, not four times.
