Why is Jupiter so much larger than all of the terrestrial planets combined?

It formed in the outer solar system where water ice was

Where does Jupiter's large magnetic field come from?

Convection in a layer of ionized hydrogen may create the magnetic field.

What are some important characteristics of the atmosphere of Jupiter? (Select all that apply.)

-Jupiter's atmosphere formed by outgassing of solids in its interior.
-The clouds are made of ices of ammonia (NH3) and water.

This diagram shows the layered structure of Jupiter. Which letter labels the zone that consists of metallic hydrogen?

B

How are the rings of Jupiter related to the small moons Adrastea and Metis?

A

3A - 3D

This set of photographs shows various landscapes on Io and Europa. Which image shows that the surface of Europa has been tectonically deformed?

D

Which of the following is true about the subdued crater palimpsests on Ganymede?

The grooved terrain of Ganymede ______________

is younger than its cratered terrain

On Ganymede, grooved terrain formed by which process?

Tectonic disruption of heavily cratered terrain

How did the multiple rings of Valhalla on Callisto form?

Crustal breakage as impact shock waves traveled through the surface.

Differences in the appearance of multiring basins on the Moon with those developed on Callisto are thought to be a result of which of the following?

The difference in the behavior of ice and silicates when impacted.

What is the evidence that Ganymede and Callisto have more ice in their interiors than Io and Europa do?

Ganymede and Callisto have lower densities.

4

Which letter in this image of Ganymede labels an area of grooved terrain?

C

The composition of the surface of Ganymede is most like which of the other satellites of Jupiter?

Europa

The icy layers of Jupiter's satellites increase in thickness as one moves from Europa to Callisto because ____________________. (Select all that apply.)

-the outer satellites orbit farther from the Sun

-they accreted in a thermal gradient centered around Jupiter

-the larger satellites retained more of there accretionary heat

-the inner satellites didn't out gas as much as the outer satellites

they accreted in a thermal gradient centered around Jupiter

Which of the Galilean satellites of Jupiter has the most heavily cratered surface.

Callisto

If you were a solar system explorer in search of liquid water at or near the surface, which of the satellites of Jupiter would be most likely to have it today?

Europa

Why isn't Earth's Moon heated by tidal flexing? (Select all that apply.)

-The Moon is too far away from the Earth.

-The outer part of the Moon is too rigid to flex as a result of tidal forces.

-The tidal energy is dissipated by the rise and fall of tides in Earth's oceans.

-The orbit of the Moon is nearly circular.

-Earth only has one large moon, unlike Jupiter.

-The orbit of the Moon is nearly circular.

-Earth only has one large moon, unlike Jupiter.

Would you expect to find young basaltic lavas at the surface of Callisto? Why? (Select all that apply.)

-No, because it is too cold.

-No, because it does not have silicates near the surface that could melt.

-Yes, Callisto is strongly tidally heated to create magma.

-Yes, large areas of dark, smooth plains are evidence that there are young lavas on Callisto.

The two no's
