  “Permafrost” is a thermal condition and refers to ground (i.e., soil or rock) that remains at or below 0 °C at least for two subsequent years (three in Russian terminology); permafrost is part of the cryosphere, that part of the Earth’s crust which is subject to temperatures.

Permafrost is a permanently frozen layer below the Earths surface. It consists of soil, gravel, and sand, usually bound together by rost usually remains at or below 0C (32F) for at least two years. Permafrost can be found on land and below the ocean floor. Permafrost has different layers: 1. The active layer is ground that freezes and thaws throughout the year, usually with the seasons, and serves to insulate the permafrost. 2. Permafrost is the layer, typically below the active layer, which is frozen year round. 3. Talik is unfrozen ground that lies between the active layer and the can also be found below or within the.

This situation has now changed with the high-resolution .   In really cold places, the ground can stay frozen all year. If the ground stays frozen at least two years in a row, it is called "permafrost." Different places have different amounts of permafrost. It may only occur in patches, or it may cover a large area. The colors on this map show different amounts of permafrost in areas of the Northern.
