Question

These high latitude, periglacial soils contain about half of the pool of global carbon.
A) Oxisols 
B) Spodosols 
C) Gelisols 
D) Mollisols

Quizplus · Accepted Answer

Gelisols are soils that contain permafrost within two meters of the soil surface, and are found in high latitude or high altitude areas. These soils are characterized by slow decomposition rates and therefore contain a large amount of organic matter, making them a significant carbon sink. It is estimated that approximately half of the global soil carbon pool is stored in these soils. Therefore, Gelisols are the most suitable option among the given choices.
