How does wind speed affect evaporation?

Correct answer: Strong wind removes moist air near the surface and increases evaporation

Correct answer: A. During evaporation, water molecules leave a wet surface and enter the air immediately above it. This nearby air quickly becomes moist. When wind moves across the surface, it removes or mixes away this moist layer and brings in air that is often drier and able to accept more water vapour. The vapour-pressure difference is therefore maintained, and evaporation generally increases. B is wrong because ordinary stronger wind does not always stop evaporation; it usually promotes it, although unusual conditions can affect the exact rate. C is wrong because wind speed is a recognized factor affecting evaporation. D is wrong because low wind usually allows moist air to remain near the surface and does not always cause more evaporation. Other factors, including temperature, exposed surface area, and humidity, also matter. Memory cue: wind “clears the damp layer” above water, helping more molecules escape.
