What is The East Australian Current?
When currents meet ______, they change direction. This is known as continental deflection.
What are landforms?
Starting at a depth of about 200 meters, the water temperature becomes colder as the _________ increases.
What is depth?
Waves are made of two main components
What are crests and troughs?

What is the gulf stream?
The current is almost 100 km wide, and more than ________ deep.

_________ __________currents begin closer to the poles and carry cool water to other parts of the ocean.
What is cold water?
Deep currents are mainly controlled by increases in ________ _________.
What is Water density?
_____________ are waves that require a medium. This means that they have to have some sort of matter to travel through.
What are Mechanical waves?
can reach depths of several hundred meters and lengths of several thousand kilometers.
What are surface currents
Speeds in the core of the EAC are among the strongest in the South Pacific, up to _______ mph an hour.
What is 4.5 mph?
_______ ________currents begin near the equator and carry warm water to other parts of the ocean.
What is warm water?
Are stream-like movements of ocean water far below the ocean surface. Deep currents are not controlled by wind or the Coriolis effect.
What are Deep Currents?

What are water waves and seismic waves?
global winds, the Coriolis effect, continental deflections, and the water temperature.

What are surface currents?
______ and ________affect the density of ocean water.
What is Temperature and salinity?
Ocean aves form because of ________ between the wind and the surface of the water.
What is friction?
Just as with winds, the rotation of the Earth causes surface currents to move in curved paths rather than straight lines.
What is the Coriolis Effect?
_____________ is the equivalent of 16,000 Olympic swimming pools flowing along our coastline.
What are the East Austrilian Currents?
Some surface currents warm and some cool _______ _______ year-round. This causes changes in the atmosphere that disrupt the climate in many parts of the world.
What are coastal areas?
The ______ ________ moves along the ocean floor and eventually travels toward the equator in the form of a deep current.
What is denser water?
________ _________ is a type of wave that moves through matter and then vibrates our eardrums so we can hear.
