WebFrost is the fine layer of water crystals that forms from water vapor in the air. In August, you might have felt the wet dew covering the grass in the morning. Dew forms when water … Frost is a thin layer of ice on a solid surface, which forms from water vapor in an above-freezing atmosphere coming in contact with a solid surface whose temperature is below freezing, and resulting in a phase change from water vapor (a gas) to ice (a solid) as the water vapor reaches the freezing point. In temperate … See more If a solid surface is chilled below the dew point of the surrounding humid air, and the surface itself is colder than freezing, ice will form on it.
