Which geomorphic outcome accelerates with alluvial terrace formation?

💡 Explanation

Channel incision accelerates following terrace formation because base-level lowering causes increased stream gradient and downcutting via stream power, therefore rivers erode deeper, rather than build outwards like delta progradation. The mechanism is knickpoint migration.

• Which outcome results when differential settling occurs in alluvial deposits beneath urban infrastructure?
• Which outcome follows sustained deposition of suspended sediment by aeolian processes?
• Which outcome increases erosion around groynes because of altered sediment transport?
• Following river avulsion, which process consolidates sediment during oxbow lake formation?
• Which process limits cave formation at great depth?
• Which outcome occurs when sustained explosive volcanism exceeds thresholds?
