Current = the horizontal movement of a body of water.
Causes:
Gravitational effects of sun and moon Heating and cooling of Earth’s atmosphereWinds blowing across the ocean’s surfaceChanges in salinity due to rain and evaporationThe Coriolis effect
Set - the direction of the currents motionDrift - the velocity of the currentSet & Drift represent the vector added to ship’s motion by the current
