Ocean Surface Currents (Slides 1 & 2)
Streamlike movements of water that occur at or near the surface of the ocean are called
Surface Currents
The East Australian Current is not the ___________________________
fast-flowing-warp tube
When currents meet landforms, they change direction. This is known as
continental deflection
Deep currents are mainly controlled by increases in _____________
Water Density
Waves are made of two main components ________,________
Crests and Troughs

Does
but Earth’s surface is not covered only with________
water
are stream-like movements of ocean water far below the ocean surface
Deep Current
is the vertical distance between a waves crest and its trough.
Wave Height
Surface currents are controlled by four factors: _______,_________,________,and ________
global winds, the Coriolis effect,
continental deflections, and the water
temperature.
And it does flow __________from the Great Barrier
Reef.
southward
Warm water currents begin near the equator and carry warm water to other parts of the
ocean
Deep currents are not controlled by ________ __________
wind or Coriolis effect
Ocean waves form because of ______between the wind and the surface of the water
Friction
Global winds blowing across the Earth’s surface create ___________
Surface Currents
Speeds in the core of the EAC are
among the strongest in the South Pacific, up
to ___________
4.5mph an hour
Some surface currents warm and some cool coastal areas ______ ______
year round
_________water always flows on top of denser water.
less- dense
Waves move in a ______ pattern.
circular
Surface currents flow like rivers in distinct patterns around the _______
Earth
The East Australian Current transports a staggering_____________ cubic meters of water southward each second.
40 million
This causes changes in the_________ that disrupts the climate in many parts of the world.
atmosphere
Cold air ______ the water molecules at the surface, causing them to move closer together
chills
are waves that require a medium
Mechanical waves
