Which outcome occurs when extensive bioturbation acts upon volcanic ash?

💡 Explanation

Extensive bioturbation mixes soil layers, and causes greater homogeneity because the process physically redistributes the ash and other soil components. Horizon distinctness decreases, therefore ash layer segregation blurs, rather than discrete precipitate accumulation.
