ocean surface currents slides (1 and 2)
Streamlike movements of water that occur at or near the surface of the ocean are called
surface currents
The East Australian Current flows along
the east coast of Australia
When currents meet land forms, they change direction. This is known as
continental deflection.
______ are stream-like movements of ocean water far below the ocean surface.
Deep Currents
A _______ is the highest point
crest
blowing across the Earth’s surface create surface currents.
global winds
what direction does East Australian Current go
southward
___________ currents begin near the equator and carry ___________ to other parts of the ocean.
warm water
are Deep currents controlled by wind or the Coriolis effect?
no
the _______ is the lowest point
trough
The Gulf Stream, which is one of the
longest surface currents, transports _______
times more water than all of the rivers in
the world
25
East Australian Current flows southward from the __________ Reef.
Great Barrier
___________ currents begin closer to the poles and carry _______ to other parts of the ocean.
Cold water
the water temperature becomes _________ as the depth increases.
colder
A ___________ is the distance between two adjust crests or troughs
wavelength
what is the Coriolis Effect
Because of the Coriolis Effect, currents in the Northern Hemisphere turn clockwise while currents in the Southern Hemisphere turn counterclockwise.
Speeds in the core of the EAC are
among the strongest in the South Pacific, up
to _____ mph an hour
4.5
name one place this happens, Warm-water currents create warmer climates in coastal areas that would otherwise be much cooler
Iceland
Deep currents are mainly controlled by increases in _________.
water density
____________ is the vertical distance between a waves crest and its trough
Wave height
global winds, the Coriolis effect,
continental deflections, and the water
temperature.
The East Australian Current transports a staggering _________________ cubic metres of water southward each second

name one place Cold-water currents create cooler climates in coastal areas that would be much warmer
San Francisco
___________ and _________ affect the density of ocean water
temperature and salinity
Waves move in a _________ pattern.
