Which best describes permafrost?

Question

Quizplus · Accepted Answer

Permafrost is a layer of soil or rock that remains frozen for at least two consecutive years, typically found in high-latitude and high-altitude regions. It can also occur in lower latitudes where the temperatures are consistently cold enough to maintain permafrost.

B, C, and D are incorrect because permafrost is not primarily associated with glacial areas, the surface layer of permafrost can thaw during warm seasons, and it tends to occur at higher elevations in mid-latitudes and in lower elevations at high latitudes.
