And, I suppose, the centripetal force caused by the rotation. But maybe that is the whole reason for earth being a spheroid? And correct me if I'm wrong, but the local depth of the sea should not matter, as water would fill the depth before the levels stabilized. But perhaps the local volume of the water affects the size of the effects of tidal forces and local land mass.
