Ganymede+Europa= icy surface with possible liquid interiors.

Io is covered in volcanos

Callisto is a mixture of water and C02 ice and silicate rock.

Ganymede, Europa and Io are in an orbital resonance, creating tidal heating and making the liquid interior of Europa possible.

For more details, Google them.  They are very interesting places.

Io is the closest moon to Jupiter and the second smallest in size. Yellow and reddish colored and is volcanically active.

Europa is the smallest and second moon from Jupiter. Smooth surface of ice with possibly liquid water below due to Geothermic activity.

Ganymede is the largest and third moon. Mottled gray surface with a mixture of ancient rocky and relatively young icy regions.

Callisto is the second largest and outermost moon, dark but heavily cratered and sprinkled with ejecta from meteor collsions.
