    • D. 

      None of the above

  • 4.

      Differential rotation

      Rotational disparity

      All of the above

    • E. 

      None of the above

  • 5. 
    Because Jupiter is so large, its period of rotation is:
    • A. 

      Similar to the period of revolution of Mercury around the Sun

    • B. 

      Similar to the period of rotation of the planet Venus

    • C. 

      Too slow to be measurable

    • D. 

      None of the above

  • 6. 
    On Jupiter the varitaion of rotational period with latitude means that the period is greatest (ie. the "day" is longest):
    • A. 

      At the equator

      Halfway between the equator and the poles

    • C. 

      At the poles

      At the equator in spring/fall and at the poles in summer/winter

    • E. 

      None of the above

  • 7. 
    The rotation period of the planet can also be measured from periodic radio emission (tied to the magnetic field of Jupiter).  This rotation period most closely agrees with the atmospheric rotation observed:

      Halfway between the equator and the poles

    • C. 

      At the poles

    • D. 

      At the equator in spring/fall and at the poles summer/winter

    • E. 

      None of the above

  • 8. 
    The "banded" structure of Jupiter's clouds:

      Is most visible near the equator and at mid-latitudes

    • C. 

      Is most visible only near the poles

    • D. 

      Varies with time but equally visible at all latitudes

    • E. 

      None of the above

  • 9.
