← GeographyWhich process dominates mineral soil formation during pedogenesis?
A)Chemical weathering of parent material✓
B)Physical aggregation by microorganisms
C)Erosion-driven sediment deposition
D)Biomass accumulation from forest litter
💡 Explanation
Chemical weathering dominates mineral soil formation during pedogenesis because hydrolysis, oxidation, and carbonation reactions break down rocks; therefore, smaller mineral particles form, rather than larger clasts accumulating via erosion, or solely from from bioturbation or organic deposition.
