Ocean surface currents slide(1,2)
Streamlike movements of water that occur at or near the surface of the ocean
what is ocean currents
flows along
the East Coast of Australia
east Australien current
definition of continental deflection.
When currents meet landforms, they change direction
stream-like movements of ocean water far below the ocean surface
deep currents
A wavelength definition
the distance between two adjust crests or troughs
surface currents are controlled by 4 factors
what is
global winds, the Coriolis effect,
continental deflections, and the water
temperature.
flow along
the East Coast of Australia
Australian eastern current
begin near the equator and carry warm water to other parts of the ocean
Warm water currents
affect the density of ocean water
Temperature and salinity
A crest definition
is the highest point
one of the
longest surface currents
What is the gulf stream
That is the equivalent of 16,000 Olympic swimming pools flowing along our coastline, every second
East Australian Current
begins closer to the poles and carry cool water to other parts of the ocean
Cold water currents
gets denser when it becomes saltier or gets colder
Ocean water
why do ocean waves form
because of friction between the wind and the surface of the water
blowing across the Earth’s surface to create surface currents
global winds
current is almost 100 km wide
East Australian Current
affects the climate in many parts of the world
Surface currents greatly
becomes colder as the depth increases
the water temperature
What moves in a circular pattern
Waves
causes surface currents to move in curved paths rather than straight lines
rotation of the earth
current more than 1.5 km deep
more than 1.5 km deep
create warmer climates in coastal areas that would otherwise be much cooler (Iceland)
Warm-water currents
always flows on top of denser water.
Less-dense water
What are Mechanical waves
waves that require a medium
