Which of the following best describes the equinox?

Question

Quizplus · Accepted Answer

The equinox occurs twice during the year and marks the point at which day and night are approximately equal in length for all locations on Earth. This is because the tilt of Earth's axis is neither towards nor away from the sun, resulting in equal illumination of both hemispheres. Therefore, option B is the correct answer. Option A is incorrect as the equinox occurs twice, not four times. Option C is incorrect as the longest day of the year occurs during the summer solstice. Option D is incorrect as the subsolar point is at the equator during the equinox, not at one of the tropics.
