Tides
What usually has the greatest influence in causing tides?
the moon
The major warm current in the West Atlantic Ocean
Gulf Stream
Crest
Back and forth motion.
oscillation
Makes one of the longest sea migrations at over 16,000 miles!
Pacific leatherback sea turtle
The very high tides that occur twice a month are caused by
sun, moon, and earth arranged in a straight line
Combines the effects of the Coriolis Effect, current speed, water depth to produce the direction of a current
Ekman spiral
Distance that wind blows over water's surface in one direction.
Fetch
A strong narrow surface current that carries water from the shore to the sea.
rip current
A breaker crest will often disappear over the channel of this current.
rip current
Lower-than-usual tides that occur twice each month
neap tides
The sea level in the center of an ocean gyre is usually
higher
The time it takes for 2 successive crests to pass a specified point.
wave period
Deepest depth below the ocean's surface that is affected by the wave's passage.
wave base
To escape a rip current you should swim ______ to shore.
parallel
Water piles into a heap on the side closest to the moon is called
tidal bulge
Type of density current that carries a great amount of sediment and acts like an underwater mudslide
turbidity current
Waves move through the depths of the ocean at the surface of layers with different densities.
Internal Waves
A wave deposit that connects an island or stack with the mainland.
tombolo
All moving objects not in firm contact with the earth's surface experience this.
the Coriolis effect
The tidal bulge furthest from the moon is from...
spinning of the Earth.
Often associated with very productive fisheries because it brings nutrients that support phytoplankton.
upwelling
Waves originate from the gravity of the sun/moon, wind, and
displacement of water.
Sea water density is mostly affected by _______ than by _________.
temperature, salinity
These non-water animals also migrate with ocean currents.
birds
