What would happen if Earth’s rotation started to slow down?
Earth is already slowing down and has been doing so for billions of years. At the present time, our planet is slowing down by about .002 second per century. The slowing occurs mainly because of friction between solid earth and ocean tides. Earth’s loss of rotational energy is transferred to the Moon, which goes into a wider orbit, thus lengthening the time between successive full Moons.
