The sun’s rays can be vertically overhead only up to 23½° north and south latitudes because
Answer: D
Because the earth's axis is inclined at 66½° to the plane of its orbit.
That inclination is the same as a tilt of 23½° from the vertical, so as the earth revolves the vertical rays move only between 23½°N and 23½°S. Those two limits are the Tropics of Cancer and Capricorn, and the tilt is also what gives us the seasons.
