Which soil-horizon outcome results when excessive rainfall occurs?

💡 Explanation

Leaching causes the depletion of mobile constituents in the upper soil horizons, because rainfall percolates through the soil, dissolving and carrying away soluble materials; therefore, depletion occurs, rather than accumulation due to mineral export during pedogenesis.
