what is the pattern followed by the average densities of the Galilean moons of Jupiter with increasing distance from the planet?

average density decreases with distance from the planet

The dark, reddish bands on Jupiter are called

belts

one of the most important sources of heat in the interiors of moons that orbit close to gift planets is
