Scientists have enough information to conclude that the face of Enceladus changes over time, with some vents opening and others closing due to tectonic forces similar to what occurs on the floors of some of Earth's oceans where volcanic material wells up to create new crust.
On Enceladus, however, the spreading is almost entirely in one direction, like a conveyor belt, rather than multi-directional like on Earth.
"We are not certain about the geological mechanisms that control the spreading," said Paul Helfenstein with Cornell University in New York.
"It's very unusual. You wouldn't find something like this on Earth."'' [source]
