Term
| Give the special & general laws of relativity and what they mean. |
|
Definition
1) General: There is no experiment that can show a difference between gravity & acceleration. Mass & time are connected.
2) Special: All observers measure the same speed for the speed of light. Time ticks slower near a large mass. |

|
Definition
| x2 + y2 + z2 - c2t2 = constant |
|

|
Definition
|
|
Term
| Give the basic experiments that confirm relativity and what they mean |
|
Definition
1) Advance of the perihelion of mercury. Large mass.
2) Fast electron. Small mass; E=MC2.
3) Eddington. No mass; space is curved. |

|
Term
|
Definition
| A surface feature of Venus |
|
|
Term
| Draw a diagram & explain the greenhouse effect. |
|
Definition
|
|
Term
| Using atomic masses, show how/why Venus should have a high pressure atmosphere. |
|
Definition
Atomic masses: C=12, N=14, O=16
Earth: 80% N2, N2=28
Venus≈100% CO2, 12+32=44
A gas under pressure will compress. |
|
|
Term
| Draw a graph of polar densities & explain. |
|
Definition
|
|
Term
| What information suggests Venus once had as much water as the Earth. |
|
Definition
Deuterium ratios on Venus are almost as high as on Earth.
This suggests equal initial hydrogen levels. |

|
|
Term
| Discuss radar mapping. Draw a diagram. |
|
Definition
|
|
Term
| Discuss why Phobos & Diemos should NOT be considered moons OF Mars. |
|
Definition
1) Not Spherical.
2) Impact craters are as in asteroids.
3) Phobos will impact Mars in≈250 million years. (A regular moon's orbit won't degrade). |
|
|
Term
|
Definition
| A moon OF Mars. (A moon ON Mars is a smoking crater; a moon OF Mars orbits.) |
|
|
Term
|
Definition
| A moon OF Mars. (A moon ON Mars is a smoking crater; a moon OF Mars orbits.) |
|
|
Term
| Discuss dust storms on Mars. |
|
Definition
|
|
Term
|
Definition
| A planet wide reduction in temperature due to "dust" in the sky. The dust is carried by wind caused by temperature shift. |
|
|
Term
|
Definition
| First lander on Mars but it didn't see anything due to a dust storm on Mars. |
|
|
Term
| What evidence suggests water was once on Mars. |
|
Definition
1) Flow Plains: similar to scarps but made with water.
2) H2O movement during "Mars" seasons
3) Rock formations that require water. |
|
|
Term
| Using the year 2000 Mars probes, explain the landing method. |
|
Definition
(1) Rocket
2) Even at high speeds, the thin atmosphere allows parachutes to slow velocity
3) Rockets slow decent at≈1000ft
4) Beach balls bounce |
|
|
Term
| List the types of Asteroids. Discuss each. |
|
Definition
1) Apollo: passes inside Earth's orbit. Should not exist. EX: Icarus
2) Asteroid Belt: between Mar's & Jupiter's Kirkwood gaps. EX: Ceres
3) Trojan: At the LeGrange points, many asteroids. EX: Hector, Helen
4) Far: Beyond Jupiter, might be connected to comets. EX: Chiron |
|
|
Term
| Draw a truth diagram & show why Apollo asteroids shouldn't exist. |
|
Definition
|
|
Term
| Draw a graph & explain Kirkwood Gaps of the Asteroid Belt. |
|
Definition
|
|
Term
| Discuss Trojan Asteroids. |
|
Definition
|
|
Term
| Discuss the Far asteroids. Why are they interesting. |
|
Definition
| Far asteroids emit gases that are close to those found in comets. This suggests that Far asteroids may replace Apollos & that there is a source for comets. |
