2 Frost By: Brittany Becker, and Danielle Keigley Frost Can Come in Many Varieties.

3 Frost Frost Frost, like snow, is the result of deposition of water in saturated air. If solid surfaces in contact with air that is chilled below deposition point, spicules of ice grow out from the solid surface. This is frost. Frost, like snow, is the result of deposition of water in saturated air. If solid surfaces in contact with air that is chilled below deposition point, spicules of ice grow out from the solid surface. This is frost. The size of the frost crystals depends on time, and the amount of water vapor available. The size of the frost crystals depends on time, and the amount of water vapor available. Frost is often observed around cracks in wooden sidewalks, due to the moist air escaping from the ground below.

4 Air Frost Air Frost When the temperature reaches zero, there is said to be an air frost. With an air frost, the ground can stay above freezing. This normally happens in early autumn, when the soil still has its summer heat.

5 Ground Frost Ground Frost When the temperature at night dips to three or four degrees, the forecasters will still be warning you of a ground frost. When the temperature at night dips to three or four degrees, the forecasters will still be warning you of a ground frost. This occurs because the ground can reach freezing while the air temperature remains above freezing. This occurs because the ground can reach freezing while the air temperature remains above freezing.

6 Hoar Frost Hoar Frost White crystals seen on the grass on a cold morning, are not ground, or air frost. This is Hoar Frost. White crystals seen on the grass on a cold morning, are not ground, or air frost. This is Hoar Frost. Hoar Frost forms when the air cools, and the water condenses onto the grass. Hoar Frost forms when the air cools, and the water condenses onto the grass. Some people think that hoar frost, and frozen dew are the same things. But, they really arent!

7 Hoar Frost, and Frozen Dew Hoar Frost, and Frozen Dew Hoar Frost Hoar Frost Hoar Frost is not completely frozen. Hoar Frost is not completely frozen. It looks more bumpy. It looks more bumpy. Hoar frost is VERY delicate. Hoar frost is VERY delicate. Frozen Dew Completely frozen. Very smooth. Not as delicate as hoar frost. Isnt that confusin g?
