The Evidence of Earth's Rotation

The video explains Earth's rotation, which occurs at about 1600 km/h at the equator. Despite this speed, we don't feel the motion due to Earth's size. Evidence of this rotation includes the cycle of day and night. The Earth spins around an axis running from the North Pole to the South Pole, completing one rotation every 24 hours. This rotation causes the sun to appear to rise and set, creating the day and night cycle. At night, the sun is on the opposite side of the Earth, and as the Earth continues to spin, the sun reappears in the east at sunrise.
