Ocean surface currents slides 1,2
Stream-like movements of water that occur at or near the surface of the ocean are called_
Surface Currents.
The East Australian Current does flow along the East coast of_
Australia
When currents meet land forms, they change_
direction
Deep currents are stream-like movements of ocean water far below the _
ocean surface
Waves are made of two main components - crests and_
troughs
Surface currents flow like rivers in distinct patterns around the_
Earth
The eastern Australian current does also flow southward from the_
great barrier ref
This is known as continental_
deflection
Deep currents are not controlled by wind or the_
Coriolis effect
A crest is the_point
highest
Surface currents are controlled by_ factors
four
Speeds in the core of the EAC are among the strongest in the South Pacific, up to_
4.5 Miles and hour
Warm water currents begin near the_
equator
Deep currents are mainly controlled by increases in_
water density
The trough is the_point
lowest
The gulf stream, flows from Florida to _
Iceland
The East Australian Current transports a staggering _cubic metres of water southward each second.
40 million
Warm water currents carry warm water to other parts of the_
ocean
Temperature and salinity affect the density of _
ocean water
A wavelength is the distance between two adjust_
crests or troughs
Global winds blowing across the Earth’s surface create _
surface currents
The current is almost_ wide
100 km
Cold water currents begin closer to the_
poles
Less-dense water always flows on top of _
denser water
Mechanical waves are waves that require a_
medium
