If dew point is below freezing and air is saturated, which surface phenomenon is possible?

Answer and explanation

Correct answer: Frost

Correct answer: A, frost. The dew point is the temperature at which air becomes saturated and water vapour begins to change into liquid water or ice. If this temperature is below 0°C and a surface cools to that level, water vapour may deposit directly as ice crystals on grass, leaves, or other exposed objects. This frozen deposit is called frost. A heat wave is a period of unusually hot weather, so B is unrelated. Boiling occurs when liquid water changes rapidly into vapour at high temperature, so C describes the opposite thermal condition. Desertification is long-term land degradation in dry areas and is not a nightly surface condensation event, so D is incorrect. Memory cue: dew point below freezing means think “frost,” while a dew point above freezing may allow ordinary dew.
