Permafrost (gelisol) is considered a hearty, robust soil type. true or false

The definition is:  A thick subsurface layer of soil that remains frozen throughout the year, occurring chiefly in polar regions.

The answer is false. Gelisols are not considered as a hearty, robust type of soil. These are the type of soils in very cold climates. They are not highly fertile type of soils because nutrients are easily leached above the permafrost such as calcium and potassium.
