Frost wedging is the process by which water/ ice weathers and erodes landscapes through repeated freeze and thaw cycles. As water freezes it expands by 9 percent, wedging the rock apart only to melt again during the summer months. The geomorphology of subarctic environments is greatly influenced by processes associated with cycles of ...

WebA local study done on frost formation relating temperature to dew point has these guidelines for frost: temperatures from 38 to 42 F can lead to patchy frost, 33 to 37 areas of frost, and 32 and below widespread frost/freeze. Note that the study did not factor in other considerations to frost, such as sky cover and wind speeds. http://overlays.acpa.org/Concrete_Pavement/Technical/Fundamentals/Frost.asp
WebFrost is a thin layer of ice on a solid surface, which forms from water vapor in an above-freezing atmosphere coming in contact with a solid surface whose temperature is below freezing, and resulting in a phase change … WebFrost action is the repeated cycle of ice formation and ice melt in the pore spaces and fractures of rocks causing disintegration of the rock. When water in rock pores freezes, its volume increases by about 10%. This can create a significant amount of pressure on rocks. The magnitude and extent of frost action is dependent on the frequency ...
