In the poles

Where do cold water currents begin?

At the equator

Where do warm water currents begin?

Density

The amount of matter ina given space, or volume

Evaporation

A process where water is removed but salt is left behind

Deep Circulation and surface circulation

What are the two current systems?

Gyre

large circular surface patterns

East

What direction is Coriolis Deflection in the Northern Hemisphere?

West

What direction is Coriolis Deflection in the Southern Hemisphere?

Upwelling

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

Sometimes follow El Nino and makes surface water unusually cool
