Which consequence results from extensive leaching in humid rainforest soils?

💡 Explanation

Leaching removes soluble base cations like calcium and magnesium, leaving behind insoluble iron and aluminum oxides. This process creates a hardpan layer through podzolization because acids from decomposing leaf litter mobilize these elements which then precipitate deeper, therefore leading to accumulation rather than their breakown by silicate weathering.
