Answer:

Particles in the solar nebula were more spread out at greater distances, so that accretion took longer and there was less time to pull in gas before the solar wind cleared the nebula.

Question 2: Why do astronomers believe that Triton is a captured moon?

Answer:

Triton orbits Neptune in a direction opposite that of Neptune's rotation.

Question 3: Why does Jupiter have three distinct layers of clouds?

Answer:

The three layers represent clouds made of gases that condense at different temperatures.

Question 4: What would happen to Jupiter if we could somehow double its mass?

Answer:

Its density would increase but its diameter would barely change.

Question 5: Why is the radiation so intense in the region that traces Io's orbit around Jupiter (the Io torus)?

Answer:

The region is full of gases that become ionized after they are released from volcanoes on Io.

Question 6: Which jovian planet should have the most extreme seasonal changes?

Answer:

Uranus Question 7: All the following statements are true. Which one is most important in explaining the tremendous tidal heating that occurs on Io?

Answer:

Io orbits Jupiter on an elliptical orbit, due to orbital resonances with other satellites.Question 8: Jupiter and the other jovian planets are sometimes called "gas giants." In what sense is this term misleading?

Answer:

They actually contain relatively little material in a gaseous state.Question 9: Which of the following gases is not a significant ingredient of the jovian planet atmospheres?

Answer:

Carbon Dioxide Question 10: Which of the following best explains why many jovian moons have been more geologically active than the Moon or Mercury?

Answer:

Jovian moons are made mostly of ice that can melt or deform at lower temperatures than can the rock and metal that make up the Moon and Mercury.Question 11: Which of the following best why we see horizontal "stripes" in photographs of Jupiter and Saturn?

Answer:

The light stripes are regions of high clouds, and the dark stripes are regions where we can see down to deeper, darker clouds.

Question 12: According to current understanding, which of the following is required in order for a planet to have rings?

Answer:

The planet must have many small moons that orbit relatively close to the planet in its equatorial plane Question 13: Which of the following is not a piece of evidence supporting the idea that Europa may have a subsurface ocean?

Answer:

Astronomers have detected small lakes of liquid water on Europa's surface.

Question 14: Which statement about Saturn's rings is not true?

Answer:

The rings must look much the same today as they did shortly after Saturn formed.

Question 15: Which of the following is most unlikely to be found on Titan?

Answer:

lakes of liquid water in the warmer equatorial regions Question 16: Uranus and Neptune have methane clouds but Jupiter and Saturn do not. Which factor explains why?

Answer:

Temperatures on Jupiter and Saturn are too high for methane to condense.
