This explores basic concepts of Venus.


Questions and Answers
  • 1. 
    The orbit of Venus is such that its angular distance from the Sun is never more than 47 degrees.  As a consequence:
    • A. 

      It can only be seen during full daylight.

    • B. 

      It is generally visible during the 2 to 3 hours just after sunset or just before sunrise.

    • C. 

      It is generally visible during the 1 to 2 hours just after sunset or just before sunrise.

    • D. 

      It can only be seen during total solar eclipses.

    • E. 

      None of the above

  • 2. 
    The rotation axis of Venus is almost perfectly at right angles to the plane of its orbit.  As a consequence Venus' seasons:
    • A. 

      Are similar to seasons on Earth.

    • B. 

      Are more extreme than seasons on Earth.

    • C. 

      Are almost non-existent (much less seasonal differences than on Earth).

    • D. 

      None of the above

  • 3. 
    Because the rotation of Venus is "retrograde":
    • A. 

      Like the Moon, Venus shows only one "face" to the Earth.

    • B. 

      Like Mercury, Venus shows only one "face" to the Sun.

    • C. 

      It turns in the opposite direction (on its axis) in comparison to the rotation of the Earth (on its axis).

    • D. 

      All of the above

    • E. 

      None of the above

  • 4. 
    The fact that the rotation of Venus is "retrograde":
    • A. 

      Was deduced by watching patterns in the cloud layers of Venus.

    • B. 

      Was deduced by watching patterns in the surface of Venus.

    • C. 

      Was deduced watching the seasonal variations of the polar ice caps.

    • D. 

      Was deduced using "Doppler broadening" of radar echoes from the surface.

    • E. 

      None of the above

  • 5. 
    Unlike Earth's atmosphere with water (droplet) clouds, Venus clouds are made from:
    • A. 

      Dry ice

    • B. 

      Sulfuric acid droplets

    • C. 

      Ozone droplets

    • D. 

      All of the above

    • E. 

      None of the above

  • 6. 
    Surface details on Venus are mainly observed using:
    • A. 

      Satellites with orbits below the cloud layers.

    • B. 

      Radar "images" from Earth and the Magellan space craft.

    • C. 

      From Russian "landers" that reached the surface of Venus.

    • D. 

      All of the above

    • E. 

      None of the above

  • 7. 
    The surface details of Venus show:
    • A. 

      Fewer "continent" like elevated regions than the Earth.

    • B. 

      About the same fraction of "continent" like elevated regions and lower "ocean" like regions as the Earth.

    • C. 

      More "continent" like elevated regions than the Earth.

  • 8.

    • A. 

      Europe

    • B. 

      Africa

    • C. 

      Asia

    • D.

    • E. 

      None of the above

  • 9. 
    Radar images from the Magellan satellite suggest:

    • B. 

      One or two isolated examples for plate tectonics on Venus.

    • C.
