Which outcome occurs when sediment deposition blocks the neck of a river meander loop?

💡 Explanation

When sediment deposition blocks a meander neck, the river abandons the loop because the flow path shortens, leading to cutoff. Therefore an oxbow lake forms, rather than a braided stream, terraces, or increased incision, which require different flow dynamics of the trunk stream system.
