  1. The greenhouse effect on Venus is due to:
    1. water vapor.
    2. sulfuric acid droplets.
    3. methane.
    4. carbon dioxide.
  2. Venus’ atmosphere is mostly:
    1. Water Vapor
    2. Nitrogen
    3. Oxygen
    4. Carbon Dioxide
  3. Who landed the first (and only) spacecraft on Venus to send back pictures?
    1. The U.S.
    2. European Space Agency
    3. Japan
    4. Russia
    5. China
  4. Why is Venus So Hot?
    1. Volcanism
    2. Meteor Impacts
    3. Runaway Greenhouse Effect
    4. Plate Tectonics
  5. What are Venus’ clouds made of?
    1. Water droplets
    2. Carbon Dioxide
    3. Windblown Dust
    4. Sulfuric Acid droplets
    5. Nitrogen
  6. In what respect is Venus most similar to Earth?
    1. size
    2. topography
    3. atmospheric composition
    4. surface temperature
  7. Which of the following is not characteristic of Mercury?
    1. a strong magnetic field
    2. heavy cratering of its surface
    3. rapid rotation
    4. extensive lava plains
    5. possible polar ice caps
  8. A major factor in explaining why Venus lacks plate tectonics
    1. It lacks water
    2. It rotates too slowly
    3. It rotates too quickly
    4. It is too close to the Sun
    5. It lacks a Moon
  9. The process that locks Mercury's rotation to its orbital motion
    1. Precession
    2. Radiation pressure
    3. Centrifugal Force
    4. Tidal forces
    5. Retrograde motion
  10. The fact that Venus lacks water does what to the rocks of its crust?
    1. Makes them stronger
    2. Makes them weaker
    3. Has no effect
    4. Means water soluble rocks are possible on Venus
    5. Makes them richer in silica
  11. Craters on Venus are very uniformly distributed, leading many planetary geologists to conclude:
    1. Impacting objects are very uniformly distributed
    2. Many craters have gone undiscovered
    3. Most impacting objects fail to penetrate the atmosphere
    4. Venus largely escaped cratering
    5. The entire surface is roughly the same age
  12. If water vapor on a planet reaches the upper atmosphere, it can be lost by
    1. Evaporation
    2. Gravitational pull of other planets
    3. Condensation
    4. Photodissociation
    5. Chemical reactions
  13. Venus has an unusual rotation in what way?
    1. Very fast
    2. It rotates at varying speeds
    3. Its axis is very highly tilted
    4. Opposite the rotation of all other planets
    5. It always shows the same side to the Sun
  14. Mercury rotates ___ times for every ___ orbits around the Sun
    1. 3...2
    2. 2...3
    3. 1...2
    4. 2...1
    5. 1...1
