The rotation of the Earth on its axis is the main cause of day and night. As the Earth rotates, different parts of its surface are exposed to or hidden from the Sun's light, resulting in the alternation between day and night.
During one complete rotation of the Earth, which takes approximately 24 hours, each location on the planet has its turn toward the Sun, experiencing daylight. This side facing the Sun receives direct sunlight, causing it to appear bright and creating daytime. Meanwhile, the other side of the Earth remains facing away from the Sun, resulting in darkness and the observation of night.
As the Earth continues to rotate, the position of the Sun appears to change in the sky, giving rise to the movement of shadows and changes in illumination. This movement is responsible for the transition from day to night and vice versa. The regular cycle of day and night is integral to the concept of time and forms the basis for daily routines and biological rhythms.
