Detailed explanation-3: -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-4: -The Earth and sun are part of the solar system, with the sun at its centre. An Earth day is 24 hours because the Earth spins on its axis once every 24 hours. At any one time half of the Earth’s sphere is in sunlight (day) while the other half is in darkness (night).
