At a sea coast, strong daytime wind increases evaporation because what does wind do?

Answer and explanation

Correct answer: It removes the moist layer near the surface

Direct answer: D, wind removes the moist layer near the water surface. Evaporation occurs when water molecules escape into the air. If the air immediately above the surface becomes nearly saturated, further evaporation slows. Moving air carries this moist air away and replaces it with comparatively drier air, so the moisture gradient is renewed and more water can evaporate. Sunlight supplies energy, but wind mainly improves air exchange. A is wrong because wind does not freeze water. B is wrong because wind does not stop solar heating; sunlight generally supports evaporation. C is wrong because ordinary wind does not remove the dissolved salt from seawater. D is correct because it removes humid air and brings drier air. Memory cue: moving air removes moisture; a fan helps wet clothes dry.
