Which risk increases during rapid chemical weathering accelerating pedogenesis?

💡 Explanation

The risk of reduced topsoil organic matter increases during accelerated pedogenesis because increased weathering from acids overwhelms bioturbation. This results in lower accumulation rates from surface decomposition, therefore organic content declines rather than other mineral alteration pathways.
