Permafrost is any ground that is at or below 0°C for at least two consecutive years. Permafrost is composed of a combination of rocks, soil (cryotic), sand and organic materials that are joined together by ice and remain frozen all year long. Permafrost covers large parts of the earth and they are usually found in areas with high mountains and in high latitudes (such as in the Antarctic and Arctic regions).
