Which geological effect happens with increased bioturbation activity?

💡 Explanation

Bioturbation mixes soil layers enhancing aeration; this increased gas exchange provides increased micro-organism activity promoting soil profile development because the soil structure evolution causes distinct, visible horizons rather than reducing layering, therefore horizon formation speeds up.
