One rotation of the Earth is equivalent to what?

One rotation of the Earth refers to the complete spin of the Earth on its own axis. This rotation takes approximately 24 hours to complete, leading to the cycle of day and night that we experience. As the Earth rotates, different parts of its surface move into and out of sunlight, which creates the transition between day and night.

Thus, the result of one full rotation is that one side of the Earth experiences daylight while the opposite side is in darkness. This cycle fundamentally defines our concept of a day, making the association between one rotation and one day and night on Earth clear and accurate.
