Waves
What is a disturbance that transfers energy?
Wave
Stream like movements of water are called....
Currents
Daily changes in the level of the ocean water.
Tides
_______________ is the mass of the ocean water divided by its volume
Density
This covers three times as much of the Earth's surface as land covers.
Oceans
What vocabulary word refers to how much salt is in the water?
Salinity
What is it called when warm water from the surface currents replaces colder denser water that sinks?
Convection Currents
Tides are caused by gravitational forces between ...
Moon
Sun
Earth
How does the water particles move due to the action of waves?
rise and fall in a circular motion
How hot or cold the water is.......
temperature
What is the distance between the crest of two waves or the troughs of two waves?
Wave Length
This occurs when the winds on the surface cause the warm surface water to be replaced with colder more nutrient rich waters.
Upwelling
The largest daily tidal range made even higher by the alignment of the sun, moon and Earth.
Spring tide
How is a tsunami different from other types of ocean waves?
large volume water that is suddenly displaced up and down
What causes an increase in density that results in a deep ocean current?
warm water loses energy to its surroundings and cools
This refers to the number of waves producted in a certain amount of time.
Frequency
When currents change direction by hitting the continents or other large land mass.
Continental Deflection
The smallest daily tidal range made even higher by the alignment of the sun, moon, and Earth.
neap tides
What determines the size of a wave?
distance between the crest and trough
Which three factors directly affect surface currents in the oceans?
surface/global winds, Coriolis Effect, and continental deflection
_________ measures the amount of time it takes a wave to pass a fixed point.
wave period
This is caused by the Earth's rotation on its axis. Circulating air is deflected toward the right in the Northern Hemisphere and toward the left in the southern hemisphere.
Coriolis Effect
This referes to the difference between high tide and low tide?
Tidal Range
What two things determine the density of ocean water?
salinity and temperature
Which Current did Nemo's father ride while searching for him?
East Australian Current
