Surface Currents 1+2
Streamlike movements of water that occur at or near the surface of the ocean are called
Ocean Currents
The East Australian Current does flow along the
East Cost of Australia
When currents meet landforms
they change directions
Deep currents are stream-like movements of
ocean water far below the ocean surface
A crest is
the highest point of a wave
Surface currents flow like rivers in distinct patterns around
The East Australian current flows ______ from the Great Barrier Reef
southward
Warm water currents begin near
the equator
Deep currents are mainly controlled by
increases in water density
Waves are made of two main components
troughs and crests
Global winds blowing across the Earth’s surface create
Surface Currents
The East Australian Current transports
40 million cubic metres of water each second
Surface currents greatly affect the
climate
What effects the dendity of ocean water
A wavelength is
the distance between two adjust crests or troughs
Because of the Coriolis Effect
currents in the Northern hemisphere turn clockwise while currents in the southern hemisphere turn counterclockwise.
The current is almost
100km wide
What is a Continental delectation
when currents meet land
Less dense water floats on
water
Wave height is
the vertical distance between a waves crest and its trough.
Surface currents are controlled by four factors, what are they?
global winds, the Coriolis effect,
continental deflections, and the water
temperature.
The current is how deep?
1.5km
If Earth's surface were covered only with water, currents would travel in
a fixed pattern around the Earth
Ocean water gets denser when
it becomes saltier or colder
Mechanical waves require what?
A medium
