|
|
Term
|
Definition
A system with many variables highly dependent on initial conditions.

|
|
Term
| List the properties of a gas giant. |
|
Definition

Term
|
Definition
| The East/West deflection of a North/South moving object on a spinning object. |
|
|
Term
|
Definition

Term
|
Definition
When the solid, liquid, & vapor form of a molecule can exist at the same time.
EX: Titan: moon of Saturn with Methane at the Triple Point. |
|
|
Term
| Discuss Titan. What makes it interesting. |
|
Definition
| Methane @ Triple Point: this means that Titan has an "ocean". This gives a moderation of temperature that makes life "possible". |
|
|
Term
| List the three most likely places in our solar system (other than Earth); give a pro and a con for each place. |
|
Definition
- Europa:
- Pro: Substantial water with ice insulation
- Con: Jupiter's Magnetic Field
- Mars
- Pro: Thin atmosphere; probable sub-surface water
- Con: No atmospshere
- Titan
- Pro: Triple Point
- Con: Very cold

|
Definition
1) Rotation axis is tilted by 90°
2) Rotation & magnetic field axis are not aligned.
3) Miranda: moon that appears to have reassembled |
|
|
Term
|
Definition
|
|
Term
| Draw at least three diagrams showing how a major gravity event could explain Uranus. |
|
Definition
|
|
Term
| Discuss why Jupiter should have a magnetic field. |
|
Definition
1) Spin: ≈10 hours
2) Free electrons: hydrogen under pressure acts like a metal. |
|
|
Term
| Discuss the volcanoes of IO. How are they useful? |
|
Definition
1) Due to tidal effects, IO is heated.
2) This produces volcanoes.
3) The ejecta can escape.
4) It interact with Jupiter's magnetic field which allows us to measure it. |
|
|
Term
Draw a graph of stellar occultation. How did this impact the study of Neptune.
It showed that we can only see rings on one side of Neptune! |
|
Definition
|
|
Term
| Discuss the difficulties of taking data at Neptune. |
|
Definition
1) Low light levels
2) Fast speed at close approach
3) (Astronaut's favorite) speed of light =8 hour delay |
|
|
Term
|
Definition
| A region of comets/asteroids beyond Pluto. Source of short period comets. (Short orbits.) |
|
|
Term
|
Definition
| A region of comets/asteroids beyond Pluto. Source of long period comets. (Long orbits.) |
|
|
Term
| What evidence suggests a major impact hit the Earth ≈60 million years ago. |
|
Definition
1) Crater off Mexico of the correct age.
2) Crater size is large.
3) Iridium is found at the site
4) Quartzite is found around the site |
|
|
Term
| Draw a diagram explain why mass extinction could be explained. |
|
Definition
|
|
Term
|
Definition
| A heavy atom found with volcanoes & meteor impacts. |
|
|
Term
| Discuss how a major impact could eliminate most life on Earth. |
|
Definition

2) Salt: Destruction of seaside habitat
3) Nuclear Winter |
|
|
Term
| Blake's Ridge (Blake's Nose) |
|
Definition
| An area in the Atlantic (off the coast of Charleston) that indicates a tidal wave went over Florida. |
|
|
Term
| Discuss why Pluto should NOT be considered a planet. |

Definition
1) Orbit is inclined WRT the ecliptic
2) Passes inside Neptune's orbit
3) Barycenter is outside Pluto's surface
(4) There is a 3:2 resonance in the orbits of Pluto & Neptune. |
|
|
Term

Definition
|
|
Term
| Discuss what properties suggest Neptune had a major gravity event. |
|
Definition
1) Triton: is in retrograde orbit
2) Neried: is in a highly eliptical orbit
