Motion in the Ocean: Currents

Shallow: ships use to sail
-influenced by land mass and wind
Deep: all water in the world
-affected by salt and temperature
-with cold temperatures and more salt, it sinks
-with hot water there is less salt that rises

North: circulation clockwise
South: circulation counter clockwise
-no current on equator
-barrier islands move because of waves
Global Circulation: Thermohaline(thermo-temp and haline-salt)
