Which lists the jovian planets in order in increasing distance from the Sun? a. Jupiter, Saturn, Uranus, Pluto b. Saturn, Jupiter, Uranus, Neptune c. Jupiter, Saturn, Uranus, Neptune |
C. Jupiter, Saturn, Uranus, Neptune |
|
|
why does Neptune appear blue and Jupiter red? a. neptune is hotter which gives bluer thermal emission b. methane in Neptune's atmosphere absorbs red light c. Neptune's air molecules scatter blue light, much as Earth's atmosphere does |
B. Methane in Neptune's atmosphere absorbs red light |
|
|
Why is Jupiter denser than Saturn? a. it has a larger proportion of rock and metal b. it has a larger proportion of hydrogen c. its higher mass and gravity compress its interior |
C. it's higher mass and gravity compress its interior |
|
|
some jovian planets give off more energy than they receive because of a. fusion in their cores b. tidal heating c. ongoing contraction or differentiation |
C. ongoing contraction or differentiation |
|
|
the main ingredients of most satellites of the jovian planets are a. rock and metal b. hydrogen compound ices c. hydrogen and helium |
B. hydrogen compound ices |
|
|
why is IO more volcanically active than our moon? a. Io is much larger b. Io has a higher concentration of radioactive elements c. Io has a different internal heat source |
C. Io has a different internal heat source |
|
|
What is unusual about Triton? a. it orbits its planet backward b. it does not keep the same face towards it planet c. it is the only moon with its own rings |
A. it orbits it's planet backward |
|
|
which moon shows evidence of rainfall and erosion by some liquid substance? a. Europa b. Titan c. Ganymeade |
B. Titan |
|
|
Saturn's many moons affect its rings through a. tidal forces b. orbital resonances c. magnetic field interactions |
B. orbital resonances |
|
|
Saturn's rings a. have looked basically the same since they formed along with Saturn b. were created long ago when tidal forces tore apart a large moon c. are continually supplied with new particles by impacts with small moons |
C. are continually supplied with new particles by impacts with small moons |
|

Dark/ red bands = |
High pressure/low altitude |
|
|
Light bands = |
low pressure/high altitude |

|
Jupiter's 4 main moons |
1. Io 2. Europa 3. Ganymeade 4. Callisto |
|
|
Saturn's main moons |
Titan Mimas Enceladus |
|
|
Uranus's main moon |
Miranda |
|
|
Neptune's main moon |
Triton |
|
|
Io |
Most volcanically active in the solar system Hot because of tidal heating elliptical orbit because of orbital resonance |
|
|
Europa |
Covered with water ice Warm interior melts water and smooths surface Water Volcanism Tidal heating |
|
|
Ganymeade |
Largest moon in solar system Icy surface, not smooth though Volcanism Less tidal heating |
|
|
Callisto |
Heavily cratered Icy surface Very little tidal heating Didn't differentiate Magnetic field |
|
|
Titan |
Has atmosphere 90% nitrogen, rest is methane and ethane Liquid methane and ethane caused erosion Hydrocarbon geology No tidal heating |
|
|
Mimas |
Giant crater, looks like Death Star, called Darth Crater |
|
|
Enceladus |
Water volcanism warm interior Second place for life |
|
|
Miranda |
It got hit, dispersed, then came back together. Jagged |
|
|
Triton |
Only large moon in retrograde orbit Probably captured dwarf planet One of coldest surface because of reflectivity Use to have internal heat, but not now |
|
|
Saturn's rings |
Millions of icy particles orbiting planet Within the rings are moons |
|
|
Shepherd moons |
hold a ring in place |
|
|
Cassini division |
largest gap, caused by Mimas (moon) pulling rings |
|
|
Uranus' rings |
Around the equator, but because of tilt, it is vertical Saw rings because of stellar occultation (trying to observe atmosphere when passed in front of a star) |
|
|
Neptune's rings |
As Triton approaches Roche limit and gets closer to Neptune, it was be damaged and create a lot more rings. Enough to put Saturn to shame. |
