Which term describes the wind-driven wave that forms due to surface wind action?

• A. Wind Wave
• B. Wavelength
• C. Amphidromic Point
• D. Wind Duration

Answer: (A)

Waves created directly by wind action on the sea surface are called wind waves. The wind transfers energy to the water through friction, generating disturbances that grow into waves as long as the wind continues, with the size depending on wind speed, fetch, and wind duration. This term specifically names the type of wave produced by surface wind action. Wavelength is a property of a wave—the distance between crests—not the origin of the wave. An amphidromic point is a tidal concept, not related to wind-driven waves. Wind duration is a factor that influences how large the waves can grow, but it isn’t a name for the wave type itself.
