How does convection cause ocean currents?
During the process of convection, energy is transferred to the atmosphere, forming winds. These winds power surface currents.
During the process of convection, the heating of surface water by the sun results in upwelling.
During the process of convection, more minerals and gases dissolve in warm water. This increases the density of the warm water and causes it to sink.
During the process of convection, energy in warm water is lost to its surroundings. The water cools, becomes denser, and sinks.
