frozen ground [¦frōz·ən ′grau̇nd]
(geology) Soil having a temperature below freezing, generally containing water in the form of ice. Also known as gelisol; merzlota; taele; tjaele. Frozen Ground natural mineral and organic-mineral aggregates containing ice. They form in those parts of the upper-most layer of the earth’s crust which are frozen for a short time (seasonally) or permanently. A distinction is made between ground frozen for a short time and seasonally (less than one year), pereletoks (frozen for one to two years), and permanently frozen ground (frozen for more than two years). A further distinction is made between frozen ground containing ice and ground cooled to below 0°C that does not contain ice (called moroznye rocks). Want to thank TFD for its existence?
