Which weathering consequence results when unconsolidated pyroclastic rock persists?

💡 Explanation

Unconsolidated pyroclastic material erodes rapidly; the increased sediment load leads to headward erosion through the mechanism of stream incision, because erosion amplifies upslope. Therefore accelerated erosion is the result, rather than spheroidal weathering which requires chemical alteration or reduced pH related to ash composition.
