Which satellite of Jupiter is volcanically active?

io

what feature dominate the surface of Callisto?

large craters, densely spread over the entire surface

the inner two Galilean satellites of Jupiter differ from the outer two by having

much higher average densities and almost crater-free surfaces

what features dominate the surface of Ganymede?

old, dark, highly craters polygons separated by younger, lighter, grooved terrain

the rotation period of Jupiter is

relatively short, on the order of 10 hours.

what is the basic structure of the planet Jupiter

rocky core, liquid hydrogen mantle, gaseous atmosphere

what is the physical appearance of Jupiter as seen from the Earth or a spacecraft?

series of dark belts and light zones parallel to the equator

the major chemical constituent of the layers of material continuously being deposited on the surface of Io, the innermost moon of Jupiter, by "volcanic" action is

sulfur

how are the relative ages of the different types of terrain on Ganymede estimated?

the denser the cratering, the older is the terrain

Jupiter's satellite Ganymede

which of the following spacecraft did NOT visit Jupiter?

Viking

the Great Red Spot is

a large, long-lived storm system in Jupiter's atmosphere

Jupiter's satellite Europa is believed to be made up of

a metallic core and a rocky mantle covered by a liquid water ocean whose surface is frozen

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
