    • C. 

      The galaxy is about 100,000 light-years in diameter.

    • D. 

      One rotation of the galaxy takes about 200 million years.

  • 4. 
    What makes the North Star, Polaris, special?
    • A. 

      It is the brightest star in the sky.

    • B. 

      It is the star straight overhead.

      It is the star directly on your northern horizon.

    • E. 

      It can be used to determine your longitude on Earth.

  • 5. 
    Why is it summer in the Northern Hemisphere when it is winter in the Southern Hemisphere?
    • A. 

      The Northern Hemisphere is closer to the Sun than the Southern Hemisphere.

    • B. 

      The Northern Hemisphere is "on top" of Earth and therefore receives more sunlight.

    • C. 

      The Northern Hemisphere is tilted toward the Sun and receives more direct sunlight.

    • D. 

      The Northern Hemisphere is tilted away from the Sun and receives more indirect sunlight.

    • E. 

      It isn't: both hemispheres have the same seasons at the same time.

  • 6. 
    What causes the apparent retrograde motion of the planets?
    • A. 

      As Earth passes another planet, its gravitational pull slows down the other planet so that it appears to be traveling backward.

    • B. 

      When planets are farther from the Sun, they move slower than when they are nearer the Sun; it is during this slower period that they appear to move backwards.

    • C. 

      The other planets never really appear to move backward; the background stars shift due to Earth's revolution around the Sun.

    • D. 

      As Earth passes another planet, the other planet appears to move backward with respect to the background stars, but the planet's motion does not really change.

    • E. 

      Apparent retrograde motion is an illusion created by turbulence in Earth's atmosphere.

  • 7. 
    What is nuclear fusion?
    • A. 

      An explosion caused by putting together two volatile chemicals

    • B. 

      The process of splitting nuclei to produce energy

    • C. 

      The process of turning matter into pure energy

    • D. 

      The process of combining lightweight nuclei to make heavier nuclei

    • E. 

      A process that only occurs in bombs

  • 8.
