Threee factors directly affect the growth of wind waves-wind strength, wind duration, and:
|
fetch
|
|
|
The growth of wind waves is affected by all but one of the following wind conditions:
|
temperature
|
|
|
Rogue waves are usually the result of:
|
constructive interference
|
|
|
A deep water wave is defined as a wave moving through the water:
|
deeper then one half its length
|
|
|
Waves forming between layers of fluids of different densities are called:
|
internal waves
|
|
|
When the maximum wave size theoretically possible for wind of a specific strength, duration, and fetch is reached, is called a:
|
fully developed sea
|
|
|
When a shoreward-bound wave is propagated around an obstacle such as a rock or a breakwater, it is said to be:
|
diffracted
|
|
|
The dome of water formed by the low-atmospheric pressures at the center of a storm can be moved ashore to encounter land as a:
|
storm surge
|
|
|
Node, resonant frequency, and standing wave are all terms used in discussing a:
|
seiche
|
|
|
The seiche phenomenon is most dangerous when:
|
occurs in an enclosed or semi-enclosed body of water
|
|
|
Which of these phenomena cannot result in a tsunami?
a)rupture at a subdution zone b)glacir calving c)storm surge d)undersea volcanic eruption |
storm surge
|
|
|
The DART program for tsunami monitoring is based upon:
|
bottom-oriented pressures sensors
|
|
|
Once a tsunami is generated, its ratio of height-to-length, or steepness:
|
is very slow
|
|
|
When a tsunami comes ashore, its typical appearance is a:
|
fast moving flood of water
|
|
|
When describing the energy distribution in a tsunami's water column, you would say that:
|
it extends the full length of the column
|
|
|
When calculating the speed, or celerity, of a tsunami:
|
use the same formula as for that of a shallow-water wave:
Multiply the acceleration of gravity times the water depth and taking the square root of the answer. |
|
|
As the tsunami crest approached shore, the wave height _____, the velocity ________, and the period ________.
|
increases/drops/remains constant
|
|
|
Most seismic sea waves are generated ________, due to the seismic activity there.
|
around the Pacific Rim
