Question

The equinox

Quizplus · Accepted Answer

The equinox occurs twice during the year, in March and September, and marks the point when day and night are equal in length, approximately 12 hours each, for all locations on Earth. Therefore, option B is the correct choice. Option A is incorrect because the equinox occurs twice, not four times. Option C is incorrect because the longest day of the year is the summer solstice, which occurs around June 20-22 in the Northern Hemisphere and December 21-22 in the Southern Hemisphere. Option D is also incorrect because the subsolar point is located along the equator during the equinox, not at one of the tropics.
