Do you know that the speed of rotation of the earth is decreasing
The Earth’s rotation is gradually slowing down over time. This is a natural process, primarily caused by tidal friction, which occurs due to the gravitational interaction between the Earth and the Moon. As the Moon’s gravity pulls on the Earth’s oceans, it causes tidal bulges that exert friction on the Earth’s rotation, slowly causing it to lose rotational energy.
This process is very slow. For example, Earth’s day lengthens by about 1.7 milliseconds per century. In the distant past, the Earth had a much shorter day. Around 600 million years ago, days were only about 21 hours long. In addition to tidal friction, other factors like the redistribution of mass on Earth like; such as the melting of glaciers or changes in the atmosphere can also affect the Earth’s rotation, but tidal friction is the primary driver. Over long periods, these small changes add up, but for human time scales, the impact is not noticeable.
Earth’s rotation
The Earth’s rotation is slowing down gradually due to tidal friction caused by the gravitational pull of the Moon. This slows the Earth’s spin by about 1.7 milliseconds per century. Over millions of years, this results in longer days.
