This is the primary mechanism in determining strength and direction of surface currents
What is wind?
100
Upwelling is caused by this mechanism
What is wind blowing parallel with the coast?
100
This is the term for the peak of an ocean wave
What is a crest?
100
This is the primary cause of tsunami
What are earthquakes?
100
This object is the greatest cause of tides on earth
What is the moon?
200
This is the term for the deflection of surface currents to the right in the Northern Hemisphere and left in the Southern Hemisphere due to the earth's rotation
What is the Coriolis Effect?
200
The global conveyor belt is driven by this mechanism
What is differences in densities of water?
200
This is the term for the lowest point of an ocean wave
What is a trough?
200
This is a term for the series of wave produced in a tsunami
What is a wave train?
200
This is the usual number of high tides and low tides each day
What is 2?
300
This is the large surface current which runs up the east coast of the United States
What is the Gulf Stream?
300
This is the primary reason upwelling is important to the ecosystem
What is bringing nutrient-rich water to the surface?
300
These occur when the speed of a a wave crest excedes the trough and falls ahead of the wave
What are breakers?
300
This is the number of casualties caused by the 2004 Indian Ocean Tsunami
What is 275,000?
300
These are the terms for when low tide is approaching and when high tide is approaching
What is ebb tide and flood tide?
400
These are large ciruclar patterns of surface currents which flow clockwise in the Northern Hemisphere and counter-clockwise in the Southern Hemisphere
What are gyres?
400
This is the mechanism by which downwelling occurs
What is converging waters at the surface?
400
This is the term for the distance a wind blows over the surface producing a wave
What is fetch?
400
The Indian Ocean Tsuanmi of 2004 happened near this island
What is Sumatra?
400
What is the term for when the earth, sun, and moon are all aligned and high tides are at their highest and low tides are lowest?
What is Spring Tide?
500
These are the two factors which determine the strength of the Coriolis Effect
What is the speed of the wind and the distance from the equator?
500
How quickly does the global conveyor belt move on average?
What is 1-2 cm/sec?
500
This is the point in which a deep-water wave becomes a shallow-water wave, and begin to increase in wave height
What is when reaching a depth 1/2 of the wavelength?
500
This is the name for the current Tsunami Warning system.
What is DART (Deep-Ocean Assessment and Reporting of Tsunami)?
500
This is the two phases of the moon during neap tides
