Ocean Surface Currents
Streamlike movements of water that occur at or near the surface of the ocean
What are surface currents?
Speeds in the core of the East Australian current are among the strongest here.
What is the South Pacific?
Currents that meet landforms, change direction.
What is continental deflection?
Stream like movements of ocean water far below the ocean surface.
What are deep currents?
The distance between two adjusted crests or troughs.
What is wavelength?
The four factors that influence surface currents.
What are the Coriolis effect, global winds, continental deflections, and water temperature?
Strongest Currents in the South Pacific
What is the East Australian Current?
begins near the equator, and carry's warm water to other parts of the ocean.
What are warm water currents?
Affect the density of ocean water.
What are temperature and salinity?
The highest point of a wave.
What are crests?
Flows like rivers in distinct patterns around the Earth.
How do surface currents move?
The East Australian Current is very deep.
What is 1.5km deep?
It begins at the poles, and carry's cool water.
What are cold-water currents?
Chills the water molecules at the surface of the ocean.
What is cold air?
The lowest point of a wave.
What are troughs?
Currents in the Northern Hemisphere turn clockwise while currents in the Southern Hemisphere turn counterclockwise.
What does the Coriolis effect do?
The East Australian current transports 40 million cubic meters of water.
What is the amount of water the EAC can transport southward each second?
Some warm and some cool coastal area's year-round.
What are surface currents?
Rises to replace water, leaving in surface currents.
What is water from deep currents?
Move-in a circular pattern.
What are waves?
Transports 25 times more water than all of the rivers in the world and flows from Florida to Iceland.
What is The Gulf stream?
The EAC is very wide.
What is 100km wide?
causes changes in the atmosphere.
What are warm, and cold surface currents?
Replaces colder denser water that sinks to the ocean floor.
What is warmer water from surface currents?
Waves that require a medium.
What are mechanical waves?
