icy surface of Jupiter's satellite, Europa
at what locations are auroras seen on Jupiter?
in oval regions around Jupiter's magnetic poles but only rarely, if ever, directly over these poles
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
the existence of the Great Red Spot of Jupiter has been known since
the time of Hooke and Cassini in the 1600s
Which of the Moons of Jupiter is characterized by an exceptionally smooth, icy surface, few craters, and many streaks and cracks?
Europa
which spacecraft dropped a probe into he atmosphere of Jupiter?
Galileo
the four giant moons of Jupiter were discovered by
Galileo,in seventeenth-century italy
what is the biggest planet in the solar system?
Jupiter
which is the largest planetary satellite, larger than Mercury, in the solar system?
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
one of the most important sources of heat in the interiors of moons that orbit close to gift planets is
continuous tidal distortion from the planet and other moons
what is the source of Jupiter's intense magnetic field?
electric currents in Jupiter's liquid hydrogen layer
jupiter's satellite io is predominately yellow and orange, but it also has numerous round black spots on it surface. what are these spots?
volcanic vents

The outer three Galilean moons of Jupiter differ from Io, the innermost such moon, by having surfaces composed predominantly of
water ice
what are the light colored bands on Jupiter called?
zones
