Question

Why are day and night not of equal direction throughout the the world?​

Answer 1

This is because the Earth is not spinning upright. ... Since we learned that the Earth's axis is tilted and hence the equator is not facing the Sun directly, different places on Earth would experience unequal length of days and nights—not exactly 12 hours of day and 12 hours of night all the time.

Answer 2

Answer:

because due to rotation of earth it changes its position and half part of it has sunlight (day) and half has night
