Exam 13: Jupiter and Saturns Satellites of Fire and Ice

What conclusions were reached about the nature of the four Galilean satellites in orbit around Jupiter when images were first sent back from exploring spacecraft?

The numerous small black spots on Jupiter's satellite Io appear to be:

How many large, spherical satellites are in orbit around Jupiter?

What are the physical characteristics of the "other" (non-Galilean) satellites of Jupiter?

Volcanoes on the surface of Io are distributed:

Io has a large magnetic field. About how much of this field is created by induction rather than being generated independently by Io itself?

What would be a typical weather forecast on Titan, Saturn's largest satellite?

The surfaces of Ganymede and Callisto appear to consist of:

The spacecraft Galileo and its predecessors left many questions about Callisto unanswered. Which one of the following questions was answered by these flyby missions?

What is estimated to be the annual thickness of the layer of sulfur-laden material laid down by the "volcanoes" on Jupiter's Galilean satellite Io?

Saturn's moon Tethys shows evidence of at least one large lava flow on its surface. Based on other characteristics of Saturn's satellites, what is the most probable composition of this lava?

The densities of the four Galilean satellites of Jupiter are:

What features dominate the surface of Callisto, one of Jupiter's satellites?

Which of the following statements describes the surface of Callisto, the outer Galilean satellite of Jupiter?

Amalthea, the largest of the four innermost satellites of Jupiter, has a distinct reddish color. What is the origin of this?

Three of the Galilean satellites of Jupiter have orbital periods that are in the ratio 1:2:4. The Galilean satellite that does NOT have such a relationship is:

In order to ignite nuclear fusion in its interior, Jupiter would have to have a mass about how many times its present mass?

Europa does not generate a satellite-wide magnetic field of its own. Each of the following contributes to the lack of such a field, EXCEPT one. Which is the exception?

Saturn's satellite Titan has a size:

Which Galilean satellite shows evidence of an intrinsic (rather than induced) magnetic field?
