Which fluvial consequence results when an alluvial river experiences base-level fall?

💡 Explanation

Increased sediment terrace formation occurs during base-level fall because incision dominates over deposition, leading to valley entrenchment; therefore, terraces form rather than floodplain expansion because graded equilibrium adjusts via down-cutting.
