B The wind removes water vapour above the surface, allowing more water to evaporate.
C The wind increases the surface area of the reservoir.
D The wind causes the water to condense faster.

Worked Solution

Step 1: Evaporation is affected by humidity. Step [2-9]: Wind blows away moist air saturated with water vapour. Step [2-9]: This creates 'space' for more water molecules to escape, increasing the rate.

Correct answer: The wind removes water vapour above the surface, allowing more water to evaporate.
