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
How hot or cold is the water....
temperature
An ocean wave has a wavelength of 7m and a wave period of 6s. What is the wave speed?
42 m/s
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
Water level at the absolute lowest level
low tide
What causes most surface waves?
wind
The motion of water particles move in this pattern due to the action of waves.
In an up and down circular motion
What is the distance between the crest of two waves or the trough 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 tidal range made even higher by the alignment of the sun, moon, and Earth
Spring
Why is the timing of tides predictable?
the moon's path is predictable
Measures the amount of time it takes a wave to pass a fixed point
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
How are the sun, Earth, and the moon aligned when a neap tide occurs?
90-degree angle
What is the similarity between a neap tide and a spring tide?
each tide occurs twice a month
What three factors most directly affect surface currents in the ocean?
surface winds, Coriolis effect, and continental deflection
How do you determine the speed of a wave?
wavelength x 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
Tides are caused by gravitational forces between the:
sun, moon, and Earth
Which Current did Nemo's father ride while searching for him?
East Australian Current
