Question: Some of Mars'water is frozen in the soil and the ice caps and some was lost due to solar wind stripping but much of the original water is thought to have been lost through another mechanism. What happened to this "lost"water?
 A. it was stripped away by the magnetic field when it rapidly decreased in strength
 B. it was broken into hydrogen and oxygen by ultraviolet light and the hydrogen was lost through thermal escape
 C. it was consumed by a civilization of thirsty Martians
 D. it was vaporized during a period of intense volcanism and was lost to space through thermal escape

 B. The Kuiper belt; short period comets tend to come from random directions indicating a spherical distribution of comets called the Kuiper belt.
 C. The asteroid belt; short period comets have orbital periods similar to asteroids like Vesta and are found in the plane of the solar system just like the asteroid belt.

Question: Why isn't there a planet where the asteroid belt is located?
 A. A planet once formed here but it was broken apart by a catastrophic collision.
 B. There was not enough material in this part of the solar nebula to form a planet.
 C. There was too much rocky material to form a terrestrial planet but not enough gaseous material to form a jovian planet.
 D. Resonance with Jupiter prevented material from collecting together to form a planet.
Answer: D

Question: Why is Mars red?
 A. Because the surface is covered with heavily oxidized ("rusted") minerals.
 B. Because the atmosphere scatters more light at bluer wavelengths transmitting mostly red light.
 C. Because Mars is covered with ancient lava flows which are red in color.
 D. Because flowing water on Mars's surface altered the surface minerals several billion years ago.
Answer: A
