About 350 million years ago, a day on the Earth was around three hours shorter than today. The Earth slowed down because of the Moon. Aren’t you surprised?
The Moon can slow down the Earth, even with its weak gravitational and magnetic field. This happens when there’s a force of friction between the surface of the Earth and the tidal bulges.
During its rotation, the Earth drags the tidal bulge directly under the Moon. This causes friction between the Earth’s surface and the tidal bulge. The friction generated during this action slows down the rotation of the Earth on its axis. This results in a longer day and even a longer month.
