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 mechanism causes island arc formation when oceanic lithosphere subducts beneath other oceanic lithosphere?
• Which outcome occurs when basaltic lava cools rapidly underwater?
• Which slope instability process accelerates cirque formation in periglacial environments with freeze-thaw cycles?
• Which outcome occurs when floodplains lack riparian vegetation?
• Which process initiates headwall erosion resulting to expansion of mountain cirques?
• Which mechanism causes the uplift of mountain ranges along convergent plate boundaries?
