How does wind cause surface currents? a. wind applies a repulsive force that causes the surface ocean water to move opposite the direction of the wind current b. wind applies a frictional force that causes surface ocean water to move in a path similar to the wind currents. c. wind applies a compressive force that pushes the surface ocean water down to greater depths. d. wind applies a gravitational force that forces surface ocean water to rise up in a wave pattern.
