Which consequence results when longshore drift interacts with a river delta?

💡 Explanation

Delta lobe switching occurs more rapidly because sediment deposition during longshore drift alters river flow pathways therefore redirecting the main channel repeatedly because of the blockage rather than gradually forming new distributaries when there is a minor blockage.
