Which outcome commonly occurs when meander curvature reaches threshold?

💡 Explanation

Oxbow lake formation from meanders relies on channel avulsion via the neck cutoff mechanism; because lateral erosion exceeds bank stability, the river short-circuits, therefore isolating the meander loop, rather than processes forming deltas or incision.

• Which geological outcome primarily results from strike-slip fault interaction with an underwater, sediment-filled canyon?
• Which outcome results after permafrost degradation from solifluction?
• Which outcome occurs when sediment supply overwhelms lake subsidence?
• Which outcome results from accelerated pedogenesis in karst regions?
• Which process accelerates glacial retreat and fjord deepening when warm ocean water intrudes into a fjord system?
• Which outcome occurs when a meandering stream in a floodplain reaches its graded profile limit?
