  1. The dark flat areas on the Moon are
    1. lava plains
    2. great dust accumulations
    3. areas melted during meteor impacts
    4. parking lots for flying saucers
  2. Large lava-filled impact craters found on the moon are known as:
    1. splash marks
    2. maria
    3. breccia
    4. lunar highlands
    5. rays
  3. The dark-appearing areas on the moon are called:
    1. oceans
    2. rays
    3. lunar highlands
    4. none of the above
    5. maria
  4. The maria lowlands on the moon are most likely:
    1. large lava-filled impact craters
    2. dried up ocean basins
    3. fault block basins similar to rift valleys on earth
    4. stream eroded basins
    5. none of the above
  5. The areas of the moon called maria by the early astronomers were thought to be:
    1. mountainous regions
    2. areas of dense vegetation
    3. seas
    4. high flat plateaus
    5. deep craters
  6. The length of daylight on the moon is about:
    1. 24 hours
    2. one month
    3. 48 hours
    4. one year
    5. two weeks
  7. Most of the moon's craters were produced by:
    1. the impact of debris (meteoroids)
    2. volcanic eruptions
    3. faulting
    4. radial implosions
    5. their origin remains unknown
  8. The mountains on the moon:
    1. are folded mountains not unlike the Appalachians
    2. are fault-block mountains like the Teton Range in Wyoming
    3. are a volcanic mountains range
    4. are rims of huge impact basins
    5. have an unknown origin
  9. Bright splash marks radiating outward from large young lunar craters are called:
    1. rays
    2. spokes
    3. continuous ejecta
    4. radiating dikes
    5. spicules
  10. The surface of the Moon is divided into: light-colored cratered regions and low-lying, dark-colored plains called:
    1. highlands and maria 
    2. fold mountains and shields
    3. basaltic and granitic crust
    4. igneous and sedimentary terranes
    5. cratons and polar caps
  11. The most widely accepted theory regarding the origin of the Moon involves:
    1. capture from an independent orbit
    2. formed in orbit around the Earth
    3. breaking off from the Earth during the Earth's accretion
    4. formation resulting from a collision between the Earth and a large proto-planet
    5. none of these
  12. The youngest lunar craters are marked by:
    1. rays
    2. central peaks
    3. terraces
    4. multiple rings
  13. Winding trenches in the lunar maria are called
    1. Gullies
    2. Ravines
    3. Canyons
    4. Rilles
  14. Lunar Rilles are believed to have formed
    1. By water erosion early in the Moon's history
    2. By fast-moving lava flows eroding the surface
    3. By the collapse of hollow tubes left as lava drained away
    4. By earthquakes opening fissures in the crust
  15. The youngest large crater on the Moon is named:
    1. Tycho
    2. Copernicus
    3. Kepler
    4. Plato
