What is another word for ground frost?
Pronunciation: [ɡɹˈa͡ʊnd fɹˈɒst] (IPA) 
Ground frost is a common phenomenon which occurs when the temperature drops below freezing point, causing the moisture on the ground to freeze. It is also known as hoar frost, white frost or simply frost. Hoar frost refers specifically to the delicate crystals that form on leaves and grass, while white frost refers to the thicker layer that covers large areas. Other synonyms for ground frost include frozen dew, riming and glaze. These terms are often used interchangeably and describe the same process of water droplets freezing into ice crystals on surfaces that are at or below freezing temperature. Despite its beauty, ground frost can be dangerous for drivers and pedestrians due to its slippery nature.
