Possible Spreading Centers on EuropaThe surface of Europa shows many signs of that there may be a submerged ocean. For example, in this picture there are several dark bands that look like they could be joined at each edge. This may be a geologic feature that resembles what on Earth are called spreading ridges. Other signs of the potential for a submerged ocean include: * flooded terrain * 'freckles' * rafting, and * 'mushy' craters.
