Ocean Current
the steady flow of ocean water in a certain direction
Continental Deflection
currents changing direction when they meet a continent

At the equator
Where do warm water currents begin?
The amount of matter ina given space, or volume
A process where water is removed but salt is left behind
Deep Circulation and surface circulation
What are the two current systems?

What direction is Coriolis Deflection in the Northern Hemisphere?
What direction is Coriolis Deflection in the Southern Hemisphere?
Cold, nutrient rich water comes up to the surface and replaces warm water
El Nino
Wind moves less warm water to the Western Pacific than usual and surface temperature rises
La Nina
