Ocean currents can be generated by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes. Currents are cohesive streams of seawater that circulate through the ocean.
Vertical water movement, like upwelling, is driven by density. Ocean water density is determined by its salinity, or how many dissolved particles are in it, and the temperature. The coldest, saltiest water on Earth is the most dense, and thus sinks down in the water column when surrounded by warmer or fresher water.
