What effect does wind have on the surface of the ocean?

• A. Creates waves only
• B. Drives surface currents
• C. Increases salinity
• D. Changes water density

Answer: (B)

Wind exerts a significant influence on the surface of the ocean by driving surface currents. As wind blows across the surface, it transfers energy to the water. This interaction creates friction, which generates motion in the water layers immediately below the surface. The movement of these surface waters can establish currents that flow in specific directions, influenced by factors such as wind patterns, the Earth's rotation, and the presence of landmasses. While the wind also creates waves at the surface, its primary role in the context of currents is to initiate these larger-scale flows. Surface currents can impact various marine and weather phenomena, including heat distribution across the ocean and weather patterns. Understanding this process is crucial for sailors, as it affects navigation, weather conditions, and overall ocean behavior that can influence sailing activities. Other options, while relevant to ocean characteristics, do not directly capture the primary role of wind in relation to ocean dynamics as it pertains to currents.
