Imagine you're on a merry-go-round, holding hands with someone across from you. When you both pull your hands together, the merry-go-round spins slower, just like how the Earth slows down over time. The Moon’s gravity pulls on the Earth's oceans and land, creating tides that act like brakes on the planet's spin. Over billions of years, this gentle tug makes the day longer by about 1.8 milliseconds every century.
Examples
- Imagine the Moon is a big hand pulling the Earth, each pull makes it spin slightly slower.
- Tides in the ocean are like tiny brakes that slow down the Earth’s spinning motion.
