Scientists think that the surface of Europa may well be explained with out an ocean underneath the crust, but with motions of solid ice within the moon itself. We all know that ice can flow. This is a picture of ice flowing at the south pole, or the Antarctic region of the Earth. Ice flows very easily, but very slowly.
Glaciers are perfect examples of the fact that ice can move. Glaciers flow with a speed of about 2 inches per year.
This means that the ice inside of a moon or a planet can easily flow, move, and change, if the moon or planet is heated from within.
