Which outcome occurs when rainfall increases in subtropical regolith?

💡 Explanation

Increased rainfall accelerates soil pedogenesis via eluviation because it enhances downward mobilization of clay. This translocation causes clay minerals to accumulate at lower depths producing argillic horizons, therefore increased eluviation occurs rather than impeded chemical breakdown, or the stasis of horizons.
