Why does dew decrease after sunshine begins?

Answer and explanation

Correct answer: It evaporates

Correct answer: A, it evaporates. Dew consists of small liquid-water droplets that form on cool surfaces during the night when the surface temperature falls sufficiently. After sunrise, sunlight supplies heat to the ground, leaves, grass, and other surfaces. This heat raises the temperature of the droplets, and liquid water changes into invisible water vapour that mixes with the air. This change from liquid to vapour is called evaporation. A is correct because it describes the actual process. B is wrong because dew does not turn into rock. C is wrong because frost is a different form of surface deposit, usually associated with temperatures at or below freezing; dew does not disappear by becoming frost when sunshine starts. D is wrong because the droplets do not fall into the sea. Memory cue: sunlight heats dew, and heat helps liquid water evaporate.
