Which long-term outcome typically results when localized uplift increases the slope of terrain within an alluvial plain?

💡 Explanation

Increased slope increases the stream power, causing increased sediment entrainment via channel incision, leading to terrace formation because downcutting dominates rather than lateral migration or deposition. Therefore channel incision, not deposition downstream, is promoted.
