Over time, which mechanism causes lateral migration dynamics in meandering river channels adjacent to floodplain lakes?

💡 Explanation

When a meandering river flows near a floodplain lake, differential sediment erosion occurs along its banks because faster flow on the outer bend erodes sediment, while slower flow on the inner bend deposits sediment, causing migration. Therefore, differential erosion causes migration, rather than tectonic, thermohaline, or isobaric processes which require different geological mechanisms.

• Which erosional pattern emerges when acidic groundwater percolation weakens cave structures?
• Which effect occurs when multiple ocean gyres become more stratified due to freshwater input from melting glaciers?
• Which topographic outcome occurs when permafrost thawing triggers widespread solifluction on a hillside?
• Which outcome occurs when a meander stream's floodplain becomes highly constricted?
• Which risk increases when tectonic uplift rapidly elevates an existing alluvial fan?
• Which process drives the circulation of nutrients in deep ocean layers?
