  1. Question 14 PointsPlanetary rings are
    1. All of these
    2. composed of a large number of individual particles that orbit their planet in accord with Kepler’s third law.
    3. orbiting in the equatorial plane of their planet.
    4. known to exist for all of the jovian planets.
  2. Question 24 PointsWhich of the jovian planets has/have rings?
    1. All of these
    2. Saturn
    3. Neptune
    4. Uranus
    5. Jupiter
  3. Question 34 PointsWhich of the following best explains why many jovian moons have been more geologically active than the Moon or Mercury?
    1. Because of their greater distances from the Sun, the jovian moons receive much less heat from the Sun.
    2. Jovian moons are made mostly of ice that can melt or deform at lower temperatures than can the rock and metal that make up the Moon and Mercury.
    3. The jovian moons probably have far more internal heat generated by radioactive decay than do the Moon or Mercury.
    4. The jovian moons are considerably larger than the Moon and Mercury and therefore have retained much more internal heat.
  4. Question 44 PointsWhich of the following best explains why we see horizontal “stripes” in photographs of Jupiter and Saturn?
    1. The dark and light stripes correspond to alternating bands of different chemical composition.
    2. There are three different color stripes corresponding to the three different types of clouds found on these planets.
    3. Dark stripes are those in which there is a stratosphere and light stripes are those with no stratosphere.
    4. The light stripes are regions of high clouds, and the dark stripes are regions where we can see down to deeper, darker clouds.
  5. Question 54 PointsWhat kinds of moons orbit the Jovian planet?

    2. It is material left over from the interstellar cloud that never contracted with the rest of the gases to form the solar nebula.
    3. It is made of planetesimals formed in the outer solar system that were flung into distant orbits by encounters with the jovian planets.
    4. It is made of planetesimals between the orbits of Mars and Jupiter that never formed into a planet.

    1. It is about the size of a terrestrial planet.
    2. It is no larger than a typical mountain on one of the terrestrial planets.
    3. It is a little less than half the diameter of our Moon.
    4. It is smaller than the jovian planets but larger than the terrestrial planets.
  12. Question 124 PointsWhat is a meteorite?
    1. a small moon that orbits one of the giant planets
    2. a streak of light caused by a small particle from space burning up in Earth’s atmosphere
    3. a streak of light caused by a star moving across the sky
    4. a fragment of rock of an asteroid from the solar system that has fallen to Earth’s surface
    5. a comet that burns up in Earth’s atmosphere
  13. Question 134 PointsHow do asteroids differ from comets?
    1. Asteroids and comets are both made of rocky and icy material, but asteroids are larger in size than comets.
    2. Asteroids are made of icy material. Comets are made of rocky material.
    3. Asteroids and comets are both made of rocky and icy material, but asteroids are smaller in size than comets.
    4. Asteroids are made of rocky material. Comets are made of icy material.
  14. Question 144 PointsWhy do asteroids and comets differ in composition?
    1. Asteroids and comets formed at different times.
    2. Asteroids formed inside the frost line, while comets formed outside.
    3. Comets are much larger than asteroids.
    4. Comets formed from the jovian nebula, while asteroids did not.
    5. Asteroids are much larger than comets.
  15. Question 154 Points Each white dot in this figure represents the location of a small body in our solar system. The donut shaped ring of white dots just beyond Neptune’s orbit represents the part of our solar system that we call:  A diagram of the region beyond Neptune. 
    1. the asteroid belt
    2. the Kuiper belt
    3. the solar nebula
    4. the Oort cloud
  16. Question 164 PointsJupiter’s colors come in part from its three layers of clouds. Which of the following is not the primary constituent of one of Jupiter’s cloud layers?
    1. clouds of sulfuric acid
    2. clouds of ammonia
    3. clouds of ammonium hydrosulfide
    4. clouds of water
  17. Question 174 PointsWhy do the jovian planet interiors differ?
    1. They differ due to giant impacts at the late stages of planet formation.
    2. The more distant planets had longer to form than the closer planets, since the solar nebula lasted longer at greater distances from the Sun.
    3. Accretion took longer further from the Sun, so the more distant planets formed their cores later and captured less gas from the solar nebula than the closer jovian planets.
    4. The more distant planets formed in a cooler region of the solar nebula and therefore contain a greater proportion of ices than the closer jovian planets.
  18. Question 184 PointsAccording to our theory of solar system formation, why did Uranus and Neptune end up to be much less massive than Jupiter and Saturn?
    1. The Jovian planets farther from the Sun took longer to form and captured less hydrogen and helium gas and there was less time to pull in gas before the solar wind cleared the nebula.
    2. The size differences are thought to be a random coincidence.
    3. Ices were able to condense at the distance of Jupiter and Saturn, but only rock and metal could condense at the distances of Uranus and Neptune.
    4. The colder gas in the outer regions of the solar nebula had less gravity and therefore could not gather up into such large balls as it could closer in.
  19. Question 194 Points What is the name of the feature indicated by the arrow in this photo?  A gas giant planet. 
    1. the lo torus
    2. the Cassini Division
    3. the Great Dark Spot
    4. the Great Red Spot
  20. Question 204 PointsWhy does Jupiter have several distinct cloud layers?
    1. Clouds form randomly, so on average there are always several layers.
    2. Different layers represent clouds made of gases that condense at different temperatures.
    3. Winds prevent clouds from forming at some altitudes, so we see clouds only at the other altitudes.
    4. Different gases are present at different altitudes in Jupiter’s atmosphere.
    5. Different layers represent the various regions where the temperature is cool enough for liquid water to condense.
  21. Question 214 PointsHow do the size and mass of Jupiter’s core compare to the size and mass of Earth?
    1. It is the same size and mass.
    2. Jupiter doesn’t have a core—it is made entirely from hydrogen and helium.
    3. It is about the same size but is 10 times more massive.
    4. It is about 10 times larger both in size and mass.
    5. It is about 10 times larger in size and the same mass.

    1. weak
    2. strong 
    3. it does not have
  23. Question 234 PointsWhat evidence led astronomers to conclude that the Oort cloud is a spherical distribution of comets?
    1. the observation that comets enter the solar system from random directions
    2. Astronomers did not draw that conclusion; the Oort cloud is shaped like a flat ring in the same plane as the planets.
    3. direct observation of comets orbiting the sun in the Oort cloud
