Ocean Surface Currents (Slides 1 & 2)
What is a surface current.
Streamlike movements of water that occur at or near the surface of the ocean
What does EAC stand for
Eastern Australian Current.
When currents meet landforms, they change direction, what it this called.
continental deflection.
What is a Deep Current
are stream-like movements of ocean water far below the ocean surface.
Waves are mad of what two main components.
crests and troughs.
What way do surface currents in the Northern Hemisphere turn
Clockwise
The EAC flows what way in relation to the Great Barrier Reef.
Southwards.
Warm water currents begin where.
The equator.
What is the reason why Deep water currents are different deeper than surface currents.
Density levels.
What is wave height.
The vertical distance between a waves crest and its trough.
Surface currents are controlled by what four
factors
global winds, the Coriolis effect,
continental deflections, and the water
temperature.
The East Australian Current transports how many cubic metres of water.
40 million
Does Cold water move around to places where heated surface currents are.
Yes
Where do deep water currents travel to.
The equator
What are mechanical waves
waves that require a medium.
The Gulf Stream, which is one of the
longest surface currents, transports how many
times more water than all of the rivers in
the world
25
Speeds in the core of the EAC are
among the strongest in the South Pacific, up
to how many miles per hour.
4.5 mph
Does current patterns affect our climates.
Yes
How many meters deep does deep water currents start at.
200 Meters
How do ocean waves form
Ocean waves form because of friction between the wind and the surface of the water.
Surface currents can reach the depth of how many kilometers.
Thousands.
How many Olympic swimming pools is the EAC equivalent to
16,000
If Earth's surface was covered it water would the current patterns stay the same.
No
Deep water currents are not controlled by what.
Coriolis effect or wind.
True or False: The crest is the highest point of a wave.
True
