Frost

Frost, like snow, is the result of deposition of water vapor in saturated air. If solid surfaces in contact with the air are chilled below the deposition point (see frost point), then spicules of ice grow out from the solid surface. The size of the crystals is dependent on time and the amount of water vapor available.
