Explanation:
Detailed explanation-1: -The axial tilt of the earth’s rotation axis with respect to its orbital axis causes variations in the length of day and night on the earth’s surface from season to season.
Detailed explanation-2: -Explanation: The Equator receives direct rays of the Sun throughout the year, so the length of the day and that of the night experienced at the Equator never change.
Detailed explanation-3: -The duration of day and night is almost equal at the equator because the Equator lies exactly halfway between the two tropics and on the Solstices the Sun is directly over one of the tropics and on the Equinoxes the sun is directly over the equator.
