Why does the earth rotate on its axis?
That's interesting. Does the earth's rotation ever change?
Yes, the earth's rotation is gradually slowing down due to tidal effects. As the earth rotates, the gravitational pull from the moon causes tides to form in the oceans. This tidal friction acts as a braking force on the earth's rotation, causing it to slow down by around 1.8 milliseconds every century.
