The Evidence of Earth's Rotation

The video explains that Earth spins at about 1,600 km/h at the equator, which we don't feel due to Earth's size. This rotation causes day and night. The Earth spins around an axis from the North to the South Pole, completing one rotation every 24 hours. The apparent movement of the Sun across the sky is due to Earth's rotation. During the day, the Sun appears to rise and set because of this spinning motion. At night, the Sun is on the opposite side of the Earth. The video uses a toy spinning top to illustrate Earth's rotation and explains how this rotation results in the day-night cycle.
