Question: Where do most short-period comets come from and how do we know?
 A. The Kuiper belt; short period comets tend to be in the plane of the solar system just like the Kuiper belt.
 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:
Question: Why are the inner planets made of denser materials than the outer planets?
 A. In the beginning when the protoplanetary disk was spinning faster centrifugal forces flung the lighter materials toward the outer parts of the solar nebula.
 B. In the inner part of the nebula only metals and rocks were able to condense because of the high temperatures whereas hydrogen compounds although more abundant were only able to condense in the cooler outer regions.
 C. Denser materials were heavier and sank to the center of the nebula.
 D. When the solar nebula formed a disk materials naturally segregated into bands and in our particular solar system the denser materials settled nearer the Sun while lighter materials are found in the outer part.

Question: Why is Saturn almost as big as Jupiter despite its smaller mass?
 A. Jupiter's greater mass compresses it more thus increasing its density.
 B. Saturn has a larger proportion of hydrogen and helium than Jupiter and is therefore less dense.
 C. Jupiter's strong magnetic field constrains its size.
 D. Saturn is further from the Sun thus cooler and therefore less compact.

Answer: D

Question: Where do most short-period comets come from and how do we know?
 A. The Kuiper belt; short period comets tend to be in the plane of the solar system just like the Kuiper belt.
 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.
 D. The Oort cloud; short period comets tend to be in the plane of the solar system just like the Oort cloud.
Answer: A

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.
