← GeographyWhich long-term outcome results when intense boreal forest wildfires impact nutrient cycles?
A)Inhibited pedogenesis and soil acidification✓
B)Accelerated eluviation of surface horizons
C)Reduced permafrost thaw potential
D)Enhanced fluvial sediment deposition
💡 Explanation
In intense fires, the combustion of organic matter inhibits pedogenesis because it destroys the biomolecules necessary for soil creation; therefore, soil develops acidic conditions rather than developing through normal organic decomposition, rather than other consequences of fire.
