Which horizon generation occurs because extensive leaching concentrates recalcitrant minerals during pedogenesis?

💡 Explanation

Oxic horizon formation proceeds slowly because extreme weathering breaks down most minerals, leaving only iron and aluminum oxides; therefore oxic horizons develop gradually rather than argillic horizons which involve simply clay translocation.
