Wind on a search object can create what effect that contributes to lateral drift?

• A. Leeway
• B. Buoyancy increase
• C. Thermal expansion
• D. Magnetic interference

Answer: (A)

Wind on a surface object creates wind-driven drift known as leeway. This is the portion of the object's motion caused by the wind pushing on exposed surfaces, causing it to move laterally relative to the water current. In search and rescue and drift modeling, leeway explains why an object doesn’t follow the current exactly but veers to the side or downwind, producing a lateral component of drift. The other options don’t describe this wind-induced lateral movement: buoyancy changes affect how much of the object sits at or near the surface, not its sideways drift; thermal expansion is a temperature-related size change; magnetic interference isn’t related to wind-driven movement.
