Which of the following is an effect of wind on a search object?

• A. Friction with the water surface creates waves
• B. Increases the object's buoyancy
• C. Decreases the surface current
• D. Stops drift

Answer: (A)

Wind moving across the water pushes on the surface, creating friction that injects energy into the water and generates waves. Those surface waves are a direct effect of the wind and influence how a search object moves at the surface. Buoyancy depends on the object's density and the volume of water displaced, not on wind, so wind won’t increase buoyancy. Wind also drives surface currents and tends to cause motion (drift) rather than reducing it or stopping it. So the effect you observe from wind on a search object is the creation of waves from the surface friction.
