Question

Quizplus · Accepted Answer

Permafrost is soil or rock that remains at or below freezing for two or more consecutive years. It is found primarily in high-latitude regions but can also occur at high elevations or at lower latitudes where the ground temperature remains below freezing. The surface layer may thaw during the summer months, but there is always a layer of frozen ground beneath it.
