Abstract:
A rotating liquid body held together by gravity is not totally stable. That is, there will be differential forces acting upon the liquid in the body that cannot reach a perfect balance. Thus, the liquid within such a body will tend to move out from the center of the body to the equator, and from the equator, it will tend to flow towards the poles, where it will return towards the center of the body. Such a circulation can result in a variable and an uneven surface.
