Back

Wind, the Earth's rotation, and differences in water density.

Front

What is the difference between surface currents and deep ocean currents?

Back

Surface currents are driven by wind and affect the upper layer of the ocean, while deep ocean currents are driven by density differences and occur below the surface.

Front

What is thermohaline circulation?

Back

A global system of ocean currents driven by temperature and salinity differences.
