Answer 2

There are two main types of ocean currents: currents driven mainly by wind and currents mainly driven by density differences. Density depends on temperature and salinity of the water. Cold and salty water is dense and will sink. Warm and less salty water will float

There are two type of Ocean Currents:
Surface Currents--Surface Circulation.
Deep Water Currents--Thermohaline Circulation.
Primary Forces--start the water moving.
The primary forces are:
Secondary Forces--influence where the currents flow.
Solar heating cause water to expand.
