It is because Io is so close to Jupiter. This means "tidal forces" are caused on Io by Jupiter's gravitational field.
These forces cause distortions inside Io, leading to volcanic activity.
The moon Io is the most "volcanic" place in the solar system.
Yes, there is water on one, and volcanoes active on another.
jupiters ice moon is Io
we can't use jupiters moons for anything because fistly we can not get out that far to reach Jupiters moon and if we could it would take thousands of years and Jupiters Moons would be to big to do anything with anyway. so the answer to What could Jupiter's moons be used for? is....Nothing.
it's moons
