Following intense tropical rainfall, which outcome results when soil layers experience excessive water infiltration?

💡 Explanation

Nutrient depletion results from eluviation by water infiltration because soil particles are displaced and carried downwards through zones of leaching; therefore the topsoil loses key nutrients, rather than experiencing mechanical weathering, organic accumulation, or increased cohesion.
