Originally Answered: Why is the Moon drifting away by 1 cm each year? Because of tidal forces between moon and Earth. As Earth and moon pull each other, bulges are created on the surface.
The tide will be permanently in on that side of the Earth, and permanently out on the other. And the forces currently causing the moon to spiral outward at a current rate 3.8 cm per year will, just as its rate of departure is doing, dwindle and fall to nothing, leaving the moon in a stable orbit.
