What slowed the earth down?

The disparity between the bump’s position and the moon’s pull creates a torque on both the Earth and moon with the end result that the Earth slows down gradually. That rotational energy is transferred to the moon, which is moving away from the Earth ever so slowly, at a rate of about an inch and a half every year.
