In geology, permafrost is soil that stays at or below 0 °C (32 °F) for two or more years. It is also called cryotic soil. Most permafrost is on land close to the North and South poles.


Permafrost processes manifest themselves in large-scale land forms, such as palsas and pingos and smaller-scale phenomena, such as patterned ground found in arctic, periglacial and alpine areas.
