Permafrost
Knowledge in thermodynamics Permanently frozen ground exists in circumpolar and high-altitude regions as a balance between average air temperature and the geothermal gradient (the increase in soil temperature with depth that arises from the transfer of heat from the Earth's core). To a lesser e...
