Which outcome develops because of glacial retreat forming increased alluvial deposition?

💡 Explanation

Braided rivers form because glacial retreat leads to increased sediment load and stream gradient in alluvial zones causing channel instability. This is channel braiding, rather than single-thread channels; lower gradients cause meandering.
