STUDY GUIDE FOR TEST 3

	
			 


		Chapter 8:  The Jovian Planets
	
	Terms to know:	Jovian planets
				Metallic hydrogen
				Belts
				Zones
				Great Red Spot
				Internal heat source
				Zonal winds
				Voyager
				perturbations
				Herschel
				Leverrier

				Review Questions

	1.  Compare and contrast the terrestrial and the Jovian worlds.  
	2.  Describe the process that leads to the origin of Jupiter's zonal winds.
	3.  Describe the interior structure of the four Jovian planets.  
	4.  Describe the possible causes of Jupiter's and Saturn's internal heat sources.  Why is 
	     Saturn's internal heat source more efficient?
	5.  How is it that storms in Jupiter's atmosphere are able to last so long?
	6.  List at least 3 characteristics about Uranus that make it different than all three of the 		     other Jovian planets.
	7.  How was Neptune discovered?
	8.  Describe the seasons on Uranus.
















			Chapter 9:  Moons, Rings, and Pluto

	Terms to know:	Galilean satellites
				Co-orbital satellites
				Lagrangian points
				resonance
				Roche limit
				shepherd satellites
				Charon
				Tombaugh
				occultations

	Review Questions:	1.  Compare and contrast the four Galilean satellites of Jupiter.  
				     Describe the correlation that exists between the distance of 					     these satellites from Jupiter and geologic activity.  Why should
				     such a correlation exist?

				2.  Why is Io so extremely geologically active?

				3.  Describe the atmosphere of Titan and contrast it with the 
				     atmosphere of the Earth.

				4.  Describe the process by which two co-orbital satellites actually
				     switch orbits.

				5.  Describe Miranda's unusual geology.

				6.  Describe the evidence that Triton has active volcanism and an
				     atmosphere. Compare and contrast the atmospheres of Triton 
				     and Titan.

				7.  Describe the features that are unusual about Triton's orbit.  How
				     may it have ended in this strange orbit?

				8.  Briefly describe the main rings of Saturn. 

				9.  Compare and contrast the rings of Saturn, Uranus, Jupiter, and
				     Neptune.  

				10.  Describe the role that resonances play in creating the intricate
				       structure we see in Saturn's rings.

				11.  Describe the circumstances leading to the discovery of Pluto.

				12.  Describe how study of interactions between Pluto and its 					       moon Charon teaches us so much about both worlds.

				13.  With what solar system objects is Pluto most like?

		Chapter 10:   Asteroids, Meteoroids, and Comets

	Terms to Know:	Asteroids
				Meteors
				Meteorites
				Meteoroids
				Irons
				Stones
				Stony-Irons
				Widmanstatten patterns
				carbonaceous meteorites
				Asteroid belt
				Apollo asteroids
				Trojan asteroids
				Kirkwood gaps
				comets
				Oort cloud
				nucleus
				coma
				dust tail
				ion tail
				hydrogen cloud
				meteor shower
				radiant
				
	Review Questions:	1.  Describe how astronomers use occultations, observations of 					     reflected visible light, and visible light to determine asteroid 					     sizes.

				2.   Compare and contrast the main asteroid classes (C, S, M).

				3.  Describe the evidence that Iron meteorites may have formed 					     inside of a larger parent body.

				4.  Describe how resonances could create gaps in the asteroid belt.
		
				5.  Describe the origin of meteor showers.

				6.  Describe the structure of a comet when it is near the Sun.

				7.  What are the major constituents of a comet?  

				8.  Why is it believed that comets could yield clues about the early
				     history of the solar system?
