    C. 4, 1, 3, 2
    D. 2, 3, 4, 1
2. Massive catastrophic flood features and dry stream beds on the surface of Mars
indicate the existence of huge quantities of water in the past. Which of the following was
a likely source of this water?
     A. Volcanic gases.
     B. Organic activity.
     C. Large Martian oceans.
     D. Chemical reactions in the soil.

3. The most likely explanation for the cracks on the moon where lava has flowed through
is
    A. subduction boundaries
    B. bombardment of rocks from space.
    C. tectonic forces similar to those of Earth.
    D. expansion as the newly formed moon cooled.

4. The nebular theory of the solar system's origins explains why the
    A. outer planets are denser than the inner ones
    B. planets revolve in the same direction
    C. surface temperatures vary between the planets
    D. Earth and the moon have different origins

5. The shield volcanoes on Mars are larger that those found on Earth because Mars has
    A. no weathering
    B. less plate movement
    C. greater heat flow
    D. a thinner crust

6. Earth and Venus are two planets in the solar system on which plate tectonic activity is
suspected to continue today. This phenomenon is probably a result of their
    A. orbital velocity.
    B. similarity in age.
    C. similarity in size.
    D. distance from the sun.

7. What type of rock layer would you most expect to find at the rim of a lunar crater?
   A. Shale.
   B. Gneiss.
   C. Granite.
   D. Breccia.

8. The best reason for grouping the planets Jupiter, Saturn, Uranus, and Neptune together
is that they
     A. are closest to the sun.
     B. have Galilean moons.
     C. have rocky crusts and iron cores.
    D. have similar densities and compositions.

9. The planet most similar to Uranus in terms of mean surface temperature and equatorial
radius is
    A. Pluto.
    B. Saturn.
    C. Jupiter.
    D. Neptune.

10. A current theory for the formation of the moon suggests that a large Mars-sized
object struck Earth, ejecting a large amount of crustal and mantle material which later
condensed to form the moon. . This theory can be used to explain why the moon has a
    A. large iron core.
    B. strong magnetic field.
    C. lower density than Earth.
    D. large amount of water in its rocks.

11. The best reason for a lack of cratering on Venus, is that Venus has a(n)
    A. acidic atmosphere.
    B. weak magnetic field.
    C. variety of active geologic processes.
    D. weaker gravitational pull than Earth.

12. The most heavily cratered solid bodies in the solar system also have the
    A. deepest oceans.
    B. thickest atmospheres.
    C. least tectonic activity.
    D. highest internal temperatures.

Use the following sketch to answer questions 13 and 14.




13. The material in area X is
   A. ejecta.
   B. meteorite.
   C. lunar crust.
   D. lunar mantle.
14. Use the sketch of a cross section of a lunar crater to answer this question. The
material in area Z is
    A. of equal density to that in area X.
    B. of lower density than that in area X.
    C. of higher density than that in area X.
    D. not of measurable density.

    B. Dark, circular maria
    C. Craters with distinct rays
    D. Rough, irregular highlands
