What geological outcome can be observed as soluble minerals are removed via percolating rainwater in soil?

💡 Explanation

Spodic horizons form in soil profiles because podzolization (a form of leaching) removes iron, aluminum, and organic matter, concentrating them deeper in the soil profile; therefore, spodic horizons form rather than caliche or plateaus through alternative mineral accumulation processes.
