What is Hoar Frost?
Answers
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 to ice as the water vapor reaches the freezing point.
Answer:
Hoarfrost derives from the old English word “hoary,” meaning, getting on in age. ... To form, hoarfrost requires a supersaturated column of cold air extending well above the surface of the ground. Think a cold fog. Moisture in the air starts condensing around nuclei — particles of dust, for instance.
