[Reading guide (*.pdf)]
[CPS inquiry questions (*.pdf)]
[CPS review questions (*.pdf)]
- Describe and understand the common interior structure and processes inside of Jupiter and Saturn, the resulting exterior atmospheric features; and compare and contrast the differences between Jupiter and Saturn.
- Fig. 12.21 from Fix, Journey to the Cosmic Frontier, 4/e (*.gif)
Compare the relative sizes and amounts of gaseous and liquid metallic hydrogen of Jupiter and Saturn. And those are not giant tweezers holding Saturn!
- NASA Astronomy Pictures of the Day:
Note the difference in color and activity of the belt-zone and cyclonic weather patterns on Jupiter and Saturn.
- Provide and describe evidence of how and why Uranus and Neptune ("ice giants") are different from Jupiter and Saturn ("gas giants"); and compare and contrast the differences between Uranus and Neptune.
- NASA Astronomy Pictures of the Day:
Note the presence (or lack thereof) of prominent belt-zone and cyclonic weather patterns.
- Websites:
Understand how a giant impact theory may explain the tilt and lack of band-zone and cyclonic weather patterns on Uranus.
- Provide and describe evidence of the origin, composition, and maintenance mechanisms (gap, shepherd, and resonance satellites) of planet rings.
- Fig. 12.28 from Fix, Journey to the Cosmic Frontier, 4/e (*.gif)
Collisions between ring particles flattens their orbits (similar collisions between ring particles within a flat ring will also de-orbit the inner particle, while boosting the outer particle).
- Fig. 12.33, ibid (*.gif)
How a satellite will clear out ring particles from an inner resonance gap.
- Fig. 13.13, ibid (*.gif)
Comparing back-scattered and forward-scattered light from ring particles.
- NASA Astronomy Pictures of the Day:
Note the thick/thinness and simplicity/complexity of these rings systems, and whether these features are illuminated in forward- or back-scattered light.
- Websites:
Understand the connection between these ring features, and their interaction with the satellites that cause these features.
- Describe the evidence for and understand the causes of the geologic/hydrologic activity of satellites.
- Fig. 14.2, Fig. 14.1 from Fix, Journey to the Cosmic Frontier, 4/e (*.gif)
How the orbital resonance between Europa and Io distorts their orbits into ellipses, and how Io is especially distorted by Jupiter's tidal forces.
- In-class activity 12, Active Satellites (*.pdf)
Discuss the similarities and differences in the internal geological activity and exterior resurfacing features of these satellites.
- Landscape Comparisons--Galilean Satellites (605 KB, *.jpg)
Compare and contrast the relative impact crater densities and resurfacing features on Io and Europa (NASA Jet Propulsion Laboratory).
- Movie Showing Geysers on Triton (211 KB, *.mov)
Time-lapse images showing development of geyser, plume, and cast shadow (Solarviews.com).
- NASA Astronomy Pictures of the Day:
