Which substance accumulates when weathering decreases infiltration rates?

💡 Explanation

Clay layers accumulate in soil horizons because decreased infiltration inhibits downward movement of particles via eluviation, and weathering produces substantial clay; therefore clay accumulates, rather than being exported in sediment, sequestering carbon, or dissolving minerals.
