Well, think of how water freezes on a cold lake. There's a sharp divide because water isn't still. Heat being generated at the core of the moon would ensure warmer fluid would move towards the ice barrier, and colder fluid would move towards the core. This cycle tends to keep 'slush' from forming.
Interesting...didn't think about that. I suppose what got me thinking of the slush idea was the sheer scale of the environment compared to ours here; the entire moon is frozen. Here's some info on theories about Europa's oceans: http://en.wikipedia.org/wiki/E...
And possibly evidence of slush, depending on how you interpret the word "ductile":
...it is predicted that the outer crust of solid ice is approximately 10–30 km (6–19 mi) thick, including a ductile "warm ice" layer...
Guess there's only one way to find out. I personally can't wait!
