  1. 1Ocean Waves, do what:
    1. APropagate energy through the medium of water
    2. BMove water along in an elliptical pattern
    3. CAlways move at a constant speed
    4. DMove so that the NET motion is more than 0
  2. 2What is Period (T) ?
    1. Anumber of waves per time period (e.g. cycles per second, SI unit hertz)

    2. Bthe time for one wavelength to pass a point (e.g. seconds per cycle)

    3. CL/T, distance per time period (e.g. meters per second) often just called speed, S, or v
  3. 3What is Celerity (c)?
    1. Athe time for one wavelength to pass a point (e.g. seconds per cycle)
    2. BH/L (height divided by wavelength)
    3. CL/T, distance per time period (e.g. meters per second) often just called speed, S, or v
  4. 4What are the forces that generate waves?
    1. Awind over the ocean, atmospheric changes, landslides that fall into the water, earthquakes, gravitational attraction/rotation of the earth
    2. Bwind over the ocean, atmospheric changes, faulting of the sea floor, gravitational attraction/rotation of the earth, objects in the water (i.e boats)
    3. Cwind over the ocean, atmospheric changes, faulting of the sea floor, gravitational attraction/rotation of the earth
  5. 5What are the restoring forces that return water to its' undistributed state?
    1. ASurface tension & gravity
    2. Bwater cohesion & gravity
    3. CSurface tension & Fetch
  6. 6What factors affect the growth of wind waves? (check all that apply)
    1. AGravity
    2. BFetch
    3. CSurface tension
    4. DWind duration
    5. EWind speed
    6. FAtmospheric changes
  7. 7What are constructive interference and destructive interference?
    1. ACI: crests line up with troughs = smaller waves (lower energy packet)
      DI: crests line up, troughs line up = BIGGER WAVES (high energy packet)
    2. BCI: crests line up, troughs line up = BIGGER WAVES (high energy packet)
      DI: crests line up with troughs = smaller waves (lower energy packet)
  8. 8What is a seiche?
    1. AA wave in a enclosed or semi enclosed body of water (i.e. in a small pond or in a small bay attached to an ocean)
    2. Ba wave in a totally enclosed body of water (i.e. a small pond or lake)
    3. CA wave in a semi enclosed body of water (i.e. a small bay attached to an ocean)
  9. 9Tsunami can be caused by (check all that apply)
    1. AEarthquakes
    2. BVolcanic eruptions
    3. CRain storms
    4. DMeteor impacts
    5. ELandslides
    6. FIcebergs
  10. 10What are the differences between a wind-driven wave coming ashore and a tsunami coming ashore?
    1. Awind driven wave: (1) short wavelength &
      period (2) Breakers arrive & recede quickly

      tsunami: (1) ULTRALONG wavelength & period (2) HUGE mass of water comes ashore for SEVERAL
      MINUTES!
    2. Btsunami: (1) short wavelength &
      period (2) Breakers arrive & recede quickly

      wind driven wave: (1) ULTRALONG wavelength & period (2) HUGE mass of water comes ashore for SEVERAL
      MINUTES!
