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 force of the Earth's gravity causes the Moon to accelerate toward the Earth. Fortunately, the Moon is also moving transversely to the line joining the Moon and the Earth. Thus, the Moon never impacts the Earth, but continually falls around it.
