The terms frost line, frost depth, and freezing depth refer to the depth that the water in soil is expected to freeze. Soil, often typeset as SOiL, is a four piece rock band from Chicago Illinois United States founded by Shaun Glass Tom Schofield Tim King and Adam Zadel The frost depth depends on the climatic conditions of an area, the heat transfer properties of the soil and adjacent materials, and on nearby heat sources. Climate encompasses the temperatures humidity rainfall atmospheric particle count and numerous other meteorogical factors in a given region over long periods of In thermal physics, heat transfer is the passage of Thermal energy from a hot to a colder body For example, snow cover and asphalt insulate the ground and homes can heat the ground. Asphalt ( is a sticky black and highly viscous liquid or semi-solid that is present in most crude Petroleums and in some natural deposits sometimes termed asphaltum The term thermal insulation can refer to materials used to reduce the rate of Heat transfer, or the methods and processes used to reduce heat transfer
The term frost front refers to the varying position of the frost line during seasonal periods of freezing and thawing.
Some regions have no frost depth and some regions have several meters of frost depth. In Arctic and Antarctic locations, the freezing depth is so deep that it becomes year-round permafrost, and the term "thaw depth" is used instead. The Arctic is the Region around the Earth 's North Pole, opposite the Antarctic region around the South Pole. This article is about frozen ground For other meanings see Permafrost (disambiguation. In Soil science, the thaw depth or thaw line is the level down to which the Permafrost Soil will normally Thaw each Summer
Building codes sometimes take frost depth into account because of frost heaving which can damage buildings by moving its foundation. A building code, or building control, is a set of rules that specify the minimum acceptable level of safety for constructed objects such as Buildings and Nonbuilding Frost heaving (or frost heave) occurs when Soil expands and contracts due to freezing and thawing Foundations are normally built below the frost depth for this reason.
There are many ways to predict frost depth including n-Factors which relate air temperature to soil temperature.
