SC404.01 February 5, 2008 Page 249 Review Questions Chapter 8 5. Briefly describe Jupiter’s cloud layers. How do the cloud layers help explain Jupiter’s colors? Why are Saturn’s colors more subdued? Why are Uranus and Neptune blue? Jupiter’s cloud layers include at the highest altitude its cold enough for ammonia clouds to condense to form clouds, the next layer is slightly warmer but cold enough for ammonium hydrosulfide to condense to form clouds, and the closest layer is cold enough for water to condense to form clouds. Saturn’s colors are more subdued because less light penetrates to the depths at which Saturn’s clouds are found, and the light they reflect is more obscured by the atmosphere above them. Uranus and Neptune are blue because they are made of methane gas which absorbs red light allowing blue light to penetrate the surface. 6.

The other jovian planets also have dramatic weather patterns with faster and stronger winds then those of Jupiter. The Great Red Spot is a gigantic storm located on Jupiter. 7. What are rings? What are they made of, and how do they differ among the four jovian planets? Briefly describe the effects of gap moons and orbital resonances on ring systems. Rings are particles bunched up in some sort of orbital distances and being forced at others. They are made of particles ranging from small dust grains to boulders. Saturn’s rings are made of vast numbers if icy particles circling Saturn according to Kepler’s laws. The gravity of gap moons effectively keeps the gap clear of small ring particles and orbital resonances perform periodic nudges to reinforce one another and clear a gap in the rings....
