The frost line—also known as frost depth or freezing depth—is most commonly the depth to which the groundwater in soil is expected to freeze. 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.
The term itself is borrowed from the notion of "frost line" in soil science, which describes the maximum depth from the surface that groundwater can freeze. Each volatile substance has its own frost line (e.g. carbon monoxide, [ 1 ] nitrogen , [ 2 ] and argon [ 3 ] ), so it is important to always specify which material's frost line is referred ...
No rocks from the Paleogene or Neogene period are known from Wisconsin; however, abundant Quaternary deposits can be found as a result of the last Ice Age. The most recent glacial cycle, the Wisconsin Glaciation, began about 31,500 years ago and receded from the state by around 7,000 years ago. During this time the Lake Michigan Lobe and the ...
Despite temperatures dropping back down below freezing, most spring bulbs can tolerate a light freeze of lows in the 30s to upper 20s and do not need coverage, according to University of Wisconsin ...
The first frost of the season hits the South Shore. temperatures got into the 20's in some areas like Marshfield which left a layer of frost crystals on plants and leaves. Tuesday November 15, 2022.
The red dotted-to-solid line depicts the average temperature profile with depth of soil in a permafrost region. The trumpet-shaped lines at the top show seasonal maximum and minimum temperatures in the "active layer", which commences at the depth where the maximum annual temperature intersects 0 °C. The active layer is seasonally frozen.
