    Given that Mars' atmosphere is composed of "greenhouse gases" why is the surface temperature not higher?

    • "greenhouse" effect only works when there is significant cloud cover on the planet.
    • "greenhouse" effect only works when the "greenhouse gases" are less than a few percent of the total atmosphere on the planet.
    • Because the overall thin atmosphere there are simply not enough "greenhouse gases" to trap the infrared radiation from the planet surface.
    • All of the above
    • None of the above

    Mars appears red because:

    • Carbon dioxide in Mars' atomosphere reflects dominantly red light

    • The surface temperature of Mars means that the planet radiates dominantly in the "red" part of the spectrum.

    • Iron(rust-like) compounds in the surface material of the planet.

    • All of the above

    • None of the above

    Correct Answer
    A. Iron(rust-like) compounds in the surface material of the planet.
  • 3. 

    Carbon dioxide, in addition to being the dominant has in the Martian atmosphere, is also found:

    • In polar "ice" caps

    • Absorbed in the surface rocks

    • All of the above

    • None of the above

    Correct Answer
    A. All of the above

    Which of the following best characterizes a shield volcano?

    • It sits above a hot spot in the planet's mantle.

    • It has very steep slopes.

    • It can erupt only briefly before being dragged off the hot spot.

    • It cannot get as high as Mt. Everest bfore the thin crust starts slumping.

    • It cannot grow very large, for it has a very short span of eruption.

    Correct Answer
    A. It sits above a hot spot in the planet's mantle.
  • 6. 

    Where is the water today on Mars?

    • In "permafrost" layers

    • In permanently frozen "residual" ice caps at the north and south poles

    • All of the above

    • None of the above

    Correct Answer
    A. All of the above
  • 7. 

    The seasonal changes in the "polar caps" is largely from:

    • All of the above

    • None of the above

    Correct Answer
    A. Layers of frozen carbon dioxide (often called "dry ice")
