tidal forces evident on Io and Ganymede

Io's volcanos are the result of tidal forces even stronger than Europa's.

Ganymede has a global ocean with evidence of overturning in the distant past, similar to Europa's evidence of overturning in the more recent past. Tides explain this ocean too.

Callisto also has an ocean. I suspect but don't know that it's kept unfrozen by tides.
