Which explains how winds cause surface currents? A. Friction between the blowing air and the water drags the water along and creates surface currents. B. High-pressure air from the blowing winds presses down on the surface and creates currents. C. Winds evaporate water from the surface and increase the salt content. As the salty water sinks, it creates surface currents. D. Winds cool the surface water. As the water sinks, it creates surface currents.
