How do the lengths of day light hours and nighttime hours everywhere on earth compare on an equinox?

Answer 1

On a solstice, there are the exact same amount of daylight hours and night hours. However on an equinox, there are either more daylight hours or night hours depending what equinox it is (summer or winter).

Answer 2

As the earth rotates around the sun, it tilts back and forth on its axis

Winter time the tilt is greater and the days are shorter

Summer the tilt is less and the days are longer

Fall and spring are transitional seasons

Nearly but not quite. The axial tilt relative to the Sun does change, but over many thousands if not millions of years, not annually. From our point of view it is constant.

The Earth could be considered as moving on the surface of an imaginary cone whose vertex is the point in Space to which the extended line o fits axis would reach all year round. Consequently the planet is always leaning toward or away from the Sun, and it is this that gives the alternating North-South Hemisphere seasons.

If the tilt was less, the Summer daylights would be shorter and the Winter daylights longer. If the tilt was 0º, i.e. the axis was perpendicular to the plane of its orbit, there would be no seasonal changes and sunrise and sunset would always be 12 hours apart.

Transitional seasons? Yes - you could call them that. The change is a sine function so the daily change in dawn and dusk accelerate and decelerates regularly, hence people saying "The nights are drawing in / out now" when the rate of change is higher so noticeable.

Answer 3

Summer solstice the days in the northern hemisphere are longest and the nights are shortest. But in the winter solstice in the northern hemisphere the days are shortest and the nights are longest.

Answer 4

The hours are different than usual, because the hours are equal. There are about 12 hours of daylight & about 12 hours of darkness everywhere on Earth.
