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.
The density of the cube relative to the density of water determines if the cube will float, sink, or be neutrally buoyant: If the density of the cube is less than the density of the water, gravitational force will be less than the buoyant force (G < B), and the object will rise to the surface (Fig. 2.6 A).
