  1. 1In comparison to the planets in the solar system Mercury is:
    1. Athe smallest
    2. Bthe largest of the terrestrial planets
    3. Cthe largest
    4. Dthe smallest of the gas giants
  2. 2Mercury is roughly the size of the Moon, though, slightly larger.
    1. ARichtig
    2. BFalsch
  3. 3Mercury has not yet been explored by any space probes.
    1. ARichtig
    2. BFalsch
  4. 4Describe Mercury's interior.
    1. AMercury has a large, semi-molten, iron-nickel core, a silicate mantle, and a thin, rocky crust.
    2. BMercury has a small, solid iron-nickel core, a larger liquid outer core, a silicate mantle, and a rocky crust.
    3. CMercury has a large, solid, iron-nickel core, a rocky mantle, and a rocky crust.
    4. DMercury has a small, semi-molten, iron-nickel core, a large silicate mantle, and a thin rocky crust.
  5. 5What is unique about Mercury's rotation?
    1. AMercury rotates backwards on its axis (clockwise) whereas all the other planets rotate counterclockwise.
    2. BMercury "wobbles" as it rotates on its axis.
    3. CMercury's axis is at a 90 degree angle, so it rotates on its side.
    4. DMercury's rotation is experiencing tidal lock, which causing the same side of Mercury to face the Sun at all times.
  6. 61 year (the amount of time it takes Mercury to orbit the sun) on Mercury is shorter than 1 day (the time it takes to rotate once on Mercury's axis) on Mercury.
    1. ARichtig
    2. BFalsch
  7. 7Mercury has no magnetic field.
    1. ARichtig
    2. BFalsch
  8. 8What is unique about Mercury's orbit?
    1. AIt is the most elliptical orbit of any planet in our solar system.
    2. BIt is the most circular orbit of any planet in our solar system.
    3. CIt is perpendicular in comparison to other planets' orbits.
    4. DMercury orbits backwards around the Sun, so it moves in a clockwise path.
  9. 9Why does Mercury experience extreme temperature changes?
    1. ABecause it has no atmosphere to retain heat.
    2. BBecause of Mercury's closeness to the Sun.
    3. CBecause of Mercury's slow rotation causing long days and nights.
    4. DAll of the above
  10. 10Why does Mercury lack an atmosphere?
    1. AMercury lacks an atmosphere due to its small gravitational force.
    2. BMercury lacks an atmosphere because the Sun burns off all gas before it can create an atmosphere.
    3. CMercury lacks an atmosphere because it does not have a magnetic field to protect its atmosphere from the Sun.
    4. DMercury lacks an atmosphere because it never developed one.
