Exam 7: The Outer Planets and Their Moons

Aurorae are formed when charged particles,spiraling along magnetic field lines,collide with atoms in an atmosphere.Where are the changed particles that produce Jupiter's aurorae believed to originate?

Seasonal variations over a full Uranian year at a particular point on Uranus would:

The overall interior structure of the Jovian planets is expected to be:

The eruptions observed on Io are thought to most clearly resemble:

The expected seasonal changes on Uranus because of its orbital and spin-axis alignments,compared with those on Earth,are:

What were the results of the impacts of the fragments of Comet Shoemaker-Levy 9 into Jupiter?

What appears to be the origin of the light,grooved terrain on the surface of Ganymede?

The physical structure of Saturn's rings is:

The composition of the atmosphere of Titan,a satellite of Saturn,is MOSTLY:

Earth,which is mostly rock and iron,has a density of 5515 kg/m³.Ganymede,Jupiter's largest satellite,contains much water and water ice and has a density of 1940 kg/m³.Io has a density of 3570 kg/m³.What conclusions have astronomers drawn from this?

How would Interplanetary Travel,Inc.,advertise a holiday on Titan,one of the satellites of Saturn?

Each of the following describes a result of comet Shoemaker-Levy 9 impacting Jupiter EXCEPT ONE.Which is the exception?

The surface of Europa,one of the Galilean moons of Jupiter,appears to be covered with:

Which characteristic is thought NOT to be true of Jupiter's moon Callisto?

What appears to have caused the extensive cracking and streaking of the surface of Europa?

Like Jupiter,Saturn gives out more energy than it receives from the Sun.But unlike Jupiter,much of Saturn's excess energy comes from:

What is the mass of Saturn compared with the mass of Jupiter?

Which planet is characterized by a blue-green appearance and white,high-altitude methane clouds surrounding dark storms?

The source of intense heating in the interior of Jupiter's moon Io causing continuous and intense volcanic activity is:

Tidal flexing from Saturn appears to be responsible for interior heating of Enceladus.Which is NOT a consequence of this internal heating?
