Exam 12: Jupiter and Saturn: Lords of the Planets

There are some very narrow features in Saturn's ring system that have distinct colors. This suggests all but one of the following. Which is the exception?

When viewed in the infrared light emitted by the clouds, the brightest parts of Jupiter are:

Cassini's division in the rings of Saturn is thought to be due to gravitational forces from the moon Mimas. The orbital period of Mimas is 22.6 hours. What is the orbital period of any particles that exist within Cassini's division?

The source of Jupiter's intense magnetic field is:

In 1895 James Keeler used the Doppler shift to investigate the motions of Saturn's rings. If you look at the rings edge on, you observe a:

The reason why the individual particles within Saturn's rings have not combined together by mutual gravitational attraction to form one or two moons is that:

How do we know the nature of the white ovals in Jupiter's atmosphere?

The rings of Saturn are composed of very many small particles because they:

The relationship between the Saturnian moon Mimas and the Cassini division in the rings of Saturn is that:

The dark, reddish bands across the surface of Jupiter are known as:

Saturn's magnetosphere contains many fewer charged particles than does Jupiter's magnetosphere. Which one of the following is NOT part of the reason for this difference?

Because its interior is so hot, Jupiter radiates about twice as much heat as it receives from the Sun. How does this fraction compare with the excess energy radiated by Earth as a fraction of the energy Earth receives from the Sun?

An astronomer detects a new feature in Jupiter's atmosphere. Subsequent observation shows that this feature is brighter than its surroundings when observed in infrared light. We can conclude that this feature is a:

Which of the following exhibits differential rotation?

How permanent are the features we observe in Jupiter's atmosphere?

The distribution of mass inside the planet Saturn is believed to be concentrated more centrally than it is in Jupiter. The most important observation supporting this conclusion is that Saturn:

The oblateness of Saturn, due to its composition and rapid rotation, is:
