Which geological feature’s formation follows the cutoff of a river meander loop alongside a floodplain lake?

💡 Explanation

When a river meander loop erodes through its neck, the river straightens its course, bypassing the loop as the ends seal off by sedimentation which forms an oxbow lake. Therefore oxbow lake forms, rather than an alluvial fan, braided stream or levees, which result from different mechanisms related to sediment deposition and flow dynamics.

• Which process causes isostatic rebound when glacial ice melts completely from a substantial fjord?
• Which consequence results when excessive groundwater extraction lowers the water table beneath an alluvial aquifer?
• Which outcome results when rapid river levee aggradation slows?
• Which pedogenic effect is accelerated when earthworm bioturbation increases?
• Which mechanism accelerates lake eutrophication when agricultural runoff containing phosphorus enters?
• Which mechanism creates a stratified water column within a fjord following a glacial meltwater pulse?
