  • Permafrost

    Permafrost occurs when the ground remains at or below a temperature of 0oC for a minimum period of two years. Permafrost occurs not only at high latitudes but also at high altitudes. Almost all of the soil moisture in permafrost occurs in the form of ground ice, which in turn occurs in several...
