Exam 11: Planetary Adornmentsmoons and Rings

What are the two basic materials of which the moons in the solar system are composed? For each type of material, name an example of a moon whose surface is composed primarily of that material.

Based on the photo shown below, this moon:

The mass of all of Saturn's bright rings is comparable to the mass of:

How do Uranus's rings differ from the ring systems of the other giant planets?

Name three characteristics of a geologically active moon.

Two years after first being observed, astronomers reported that Saturn's rings vanished. What happened to them?

What leads astronomers to believe that many large moons associated with the giant planets have compositions that are roughly half water?

If a planetary ring had an inner diameter of 100,000 km, an outer diameter of 120,000 km, a thickness of 10 meters, and a density of 100 kg/m³, what would be the total mass of material in this ring?

Which of the following is FALSE?

Explain why it was difficult for the Voyager space probe to detect Jupiter's ring system as it was approaching the planet, but easy to detect the rings once it passed behind Jupiter.

Which of the following can be used as an indicator of the age of a moon's surface?

Large regular moons probably formed:

If you wanted to search for faint rings around a giant planet by sending a spacecraft on a flyby, it would be best to make your observations:

Which of the following planets has the most complex and magnificent ring system?

Europa is a very interesting moon that scientists are considering visiting with a spacecraft in order to search for signs of life. What is it about this moon that makes it so interesting, and what surface features give us clues about its interior?

Galileo discovered Saturn's rings and correctly concluded that they were formed by moons that had been tidally ripped apart.

Lakes of methane, ethane, and other hydrocarbons can be found on the surface of Saturn's moon Titan.

Which object has turned itself inside out numerous times, leading to a situation where lighter elements have escaped, sulfur compounds compose the crust, and primarily heavier elements make up its core?

What is the escape velocity from Europa, whose radius is 1,600 km and mass is 5 * 10²² kg?

What do astronomers believe causes the spoke-like features associated with Saturn's B ring?
