Oceanography Exam 2

  1. Heat is stored in the ocean during the day and released at night.

    A) FALSE
    B) TRUE
    B) TRUE
  2. A substance such as water that is a group of atoms held together by chemical bonds is called

    C) A molecule
  3. _____ gives water an unusually high surface tension.

    D) Cohesion
  4. What results in a surface "skin" capable of supporting walking insects, or running lizards.

    D) Surface Tension
  5. If hydrogen bonds did not hold water molecules together, they would form a gas rather than a liquid

    A) False
    B) True
    B) True
  6. Liquid water’s heat capacity is among the lowest of all known substances

    A) True
    B) False
    • B) False
    • Liquid water heat capacity is the highest of all known substances
  7. Water has a lower heat capacity than the Earth's crust (granite), which is why the sand at the beach in the summer time always feels cooler than the ocean.

    A) TRUE
    B) FALSE
    B) FALSE
  8. The relationship between the temperature (or salinity) of a substance and its density is represented by:

    D) Density Curve
  9. The zone in which density increases with increasing depth

    B) Pycnocline
  10. When most substances move from a gas phase to a liquid phase, and subsequently a solid phase, they become more dense. Water, however, becomes less dense in the solid phase.

    A) TRUE
    B) FALSE
    A) TRUE
  11. When water freezes, the bond angle between the oxygen and the hydrogen atoms changes from about              to              .  This change allows the hydrogen bonds to form a crystal lattice.

    C) 105 degrees; 109 degrees
  12. How many calories of heat must be added to change a gram of ice to liquid water?

    A) 80
  13. When heat input does not cause a temperature change but does produce a change in state, when water goes from liquid to gas, it is called

    B) Latent heat of vaporization
  14. Surface water has no impact on global temperature.

    A) FALSE
    B) TRUE
    A) FALSE
  15. The ocean is stratified by density, and is mainly a function of

    D) Temperature and Salinity
