Which landscape change is driven when sediment deposition obstructs a meander neck?

💡 Explanation

Oxbow lake formation is driven by neck cutoff because the sediment deposition blocks the meander neck, initiating a new, straighter channel via avulsion rather than delta lobe switching, which relates to delta progradation.
