Ocean currents Small streams in the ocean http://www.physicalgeography.net/fundamentals/images/oceancurrents.gif

Surface current When the top of the ocean water is moved by the wind and the turning of the earth. http://1.bp.blogspot.com/_iO4rWKndoMw/Sx7EfjLab1I/AAAAAAAAAB0/zJ_5wnoQcDM/s400/Convection+currents+oceans

When the earth turns, it makes the currents turn sideways.

Continental Deflection When currents hit the land, they change direction.

Deep currents Movement of water deep in the ocean. Deep currents are not affected by wind, but by how heavy the water is due to salt content and temperature.
