    • Liquid carbon dioxide

    • Liquid hydrocarbons (eg. methane)

    • None of the above

    Correct Answer

  • 6. 

    The "rocky" cratered surface of Callisto is believed to be mainly:

    • (conventional) rock

    • Ice

    • Dry ice

    • Linoleum

    • None of the above

    Correct Answer
    A. Ice
  • 7. 

    Jupiter's Galilean moons are called a "minature solar system" because:

    • Their orbits are nearly circular and lie in a plane

    • Their revolution direction (about Jupiter) are all the same

    • The average densities decrease with increasing distance from Jupiter

    • All of the above

    • None of the above

    Correct Answer
    A. All of the above
  • 8. 

    Unlike our moon, on Ganymede:

    • Light colored areas are younger and dark colored areas are older

    • Light colored areas are older and dark colored areas are younger

    • Light and dark areas are equally cratered

    • None of the above

    Correct Answer
    A. Light colored areas are younger and dark colored areas are older
  • 9. 

    Evidence  for "ongoing" volcanic activity on Io are:

    • Photos from Voyager I showing erupting volcanoes

    • Io's lack of craters is consistent with almost constant "resurfacing" by molten flows

    • Io's thin atmosphere of sulfur dioxide is consistent with recent volcanic emissions

    • All of the above

    • None of the above

    Correct Answer
    A. All of the above
  • 10. 

    If Io is "tidally locked" to Jupiter, how can gravitational energy be "pumped" into its surface?

    • Indeed; thus it must be natural radioactivity in Io's Core that "powers" the volcanic activity

    • Indeed; and it is the additional tidal interaction with Europa that "powers" Io's volcanic activity

    • Indeed; but Io's non-circular orbit means Io's tidal buldge "wobbles" back and forth as Io fails to point perfectly toward Jupiter at all points in its orbit

    • None of the above

    Correct Answer
    A. Indeed; but Io's non-circular orbit means Io's tidal buldge "wobbles" back and forth as Io fails to point perfectly toward Jupiter at all points in its orbit
  • 11. 

    It is theorized that Europa's ocean remains liquid because of:

    • Remnant heat from the formation of the moon

    • Gravitational and magnetic forces from Jupiter

    • Meteorite impacts intensified by the proximity of Jupiter

    • All of the above

    • None of the above

    Correct Answer
    A. Gravitational and magnetic forces from Jupiter
  • 12. 

    Unlike our moon, "resurfacing" on Ganymede is thought to be outflows of:

    • Magma(molten rock)

    • Water

    • Liquid carbon dioxide

    • Liquid hydrocarbons (eg. liquid methane)

    • None of the above

    Correct Answer
    A. Water
  • 13.

    • Evidence for possible tectonic motion seen in grooves and ridges

    • Vast areas with no craters

    • All of the above

    • None of the above

    Correct Answer
    A. Evidence for possible tectonic motion seen in grooves and ridges
  • 15. 

    Europa is like Io in:

    • Showing clear "ongoing" volcanic activity

    • Showing almost no cratering consistent with recent "resurfacing"

    • Having a vast network of lines crisscrossing bright, fields of water ice

    • All of the above

    • None of the above

    Correct Answer
    A. Showing almost no cratering consistent with recent "resurfacing"
  • 16. 

    The surface of Ganymede resembles our moon's suface in:

  • 17. 

    Callisto appears similar to Ganymede but with:

    • More craters and fewer fault(grooves and ridges) lines

    • Fewer craters and more fault(grooves and ridges) lines

    • Several large "basins"

    Following the variations from Terrestrial to Jovian planets:

    • Io and Europa are believed to have rocky mantles and iron cores

    • Callisto is thought to have a large, outer icy mantle with a smaller inner rocky mantle and an iron core

    • All of the above

    • None of the above

    Correct Answer
    A. Io and Europa are believed to have rocky mantles and iron cores
  • 19.

    • All of the above

    • None of the above

    Correct Answer
