Answer 2

c. permafrost

Step-by-step explanation:

Permafrost is a type of soil that occurs in the polar regions. This name is called soil that remains frozen (temperature below 0 ° C) for at least two consecutive years. The term "permafrost" was first proposed in 1943 by scientist SM Muller.

Sediments, rocks, debris permeated by ice constitute the permafrost soil. About a quarter of the earth's surface is under this type of soil. Especially in high altitude regions, permafrost is often obscured by the apparent landscape.
