What is the process by which dew quickly disappears in the afternoon?

Answer and explanation

Correct answer: Evaporation

Correct answer: B. Dew is liquid water collected on a cool surface after nearby air has cooled to its dew point. After sunrise, solar heating raises the temperature of the leaves or ground. The dew droplets gain energy and change from liquid water into invisible water vapour; this liquid-to-gas change is evaporation. B is correct because it names the process that removes the droplets from the surface. A is wrong because condensation changes vapour into liquid, the reverse direction. C is wrong because frost deposition forms ice, usually under freezing conditions, rather than removing liquid dew. D is wrong because saturation describes the moisture state of air, not the disappearance process. Memory cue: morning cooling makes dew; afternoon heating evaporates it.
