Europa Ice Flows

This is an example of terrain of Europa which has been flooded by fresh water which subsequently re-froze on the surface. The edges of the flow are "lobate" meaning rounded like a puddle of water.

This is evidence of icy-volcanism. The water of Europa may have flowed out of the ground the way lava flows out of a volcano on Earth.

Clearly, as shown in the image, the flowing water covered over some ridges on the surface which were already in place.
