Describe the cause and effect relationship between density and ocean currents.

Differences in water density affect vertical ocean currents. Denser water tends to sink, while less dense water tends to rise. Other causes of currents include tides, rain, runoff, and ocean bottom topography. Topography is the surface features of a place. Ocean topography includes slopes, ridges, valleys, and mountains! All these things are found at the bottom of the ocean, and can influence currents.
