Which mechanism fundamentally controls soil horizon differentiation during alpine pedogenesis?

💡 Explanation

Differential mineral weathering rates induce horizon separation because minerals nearer the surface break down before those deep underground via hydrolysis and oxidation; therefore soil horizons form sequentially at different depths, rather than uniformly because of physical factors.
