Which phenomenon creates crescent-shaped oxbow lakes along meandering fluvial systems?

💡 Explanation

When rivers meander, differential erosion occurs on the outside of bends and sediment deposition takes place on inside curves because of varying flow velocities creating loops which are then pinched off. Therefore oxbow formation results, reflecting erosion and deposition, rather than glacial uplift, tectonic activity, or volcanic effects which require different geological triggers.
