Answer:
WHAT DRIVES SURFACE CURRENTS?
Surface currents in the ocean are driven by global wind systems that are fueled by energy from the sun. Patterns of surface currents are determined by wind direction, Coriolis forces from the Earth's rotation, and the position of landforms that interact with the currents.
DIFFERENCES IN AIR TEMPERATURE.
Movement of air due to differences in temperature between two locations is known as convection or advection. Convection is the term commonly applied to vertical movement of air, whilst advection is used in the context of horizontal displacement of air.
DIFFERENCES IN CLIMATE.
Weather refers to short term atmospheric conditions while climate is the weather of a specific region averaged over a long period of time. Climate change refers to long-term changes.
DIFFERENCES IN WATER DENSITY.
High temperature makes water less dense. As water gets warmer, its molecules spread out, so it becomes less dense. As it gets colder, it becomes denser. Most chemicals get denser when they turn from a liquid to a solid, but water is different.
DIFFERENCES IN WATER SALINITY.
As we have seen, most differences in salinity are due to variations in evaporation, precipitation, runoff, and ice cover. All of these process occur at the ocean surface, not at depth, so the most pronounced differences in salinity should be found in surface waters.

Correct me if I'm wrong po!!
PERO HOPE IT'S HELP PO!♥
