Why Is Earth's Rotation Actually Slowing Down?

💡 The Answer

• Earth's rotation is gradually decelerating due to tidal friction caused by the Moon's gravitational pull.
• On average, the length of a day increases by approximately 1.8 seconds every century.
• Around 600 million years ago, a full day lasted only 21 hours instead of 24.
• This slowdown also causes the Moon to drift slightly further from Earth each year.
