Which outcome results when intense rainfall occurs over soil?

💡 Explanation

Intense rainfall drives leaching, which diminishes the concentration of mobile plant nutrients in the topsoil because rainwater percolates downwards, carrying the dissolved nutrients away from plant root zones; therefore plant nutrients decrease, rather than accumulate.
