Which major factor increases the rate of evaporation?

Answer and explanation

Correct answer: Strong wind

Correct answer: C. Wind increases evaporation by carrying away the moist air that lies just above a wet surface. Once this humid layer is removed, drier air comes into contact with the surface and can accept more water vapour. This keeps the difference in moisture between the surface and the surrounding air relatively large. A is wrong because low temperature usually reduces the energy available for evaporation. B is wrong because highly humid air is already close to its moisture capacity, so evaporation slows. D is wrong because a smaller surface exposes less water; a larger exposed surface generally evaporates faster under similar conditions. Other factors such as warmth and dryness also matter, but among these choices strong wind is the correct major factor. Memory cue: moving air removes the moist blanket above water.
