Which pattern emerges affecting coastal dune stability if longshore currents shift sediment supply southward?

💡 Explanation

An abrupt sediment deficit invokes down-drift dune destabilization because reduced sediment input arrests dune repair by aeolian transport, rather than vegetation thriving, therefore coastal erosion causes structural destabilization where reinforcement is absent.

• Which outcome occurs when vegetation removal alters longshore currents?
• Which process creates an alluvial fan when a high-gradient stream flows onto a valley floor with reduced slope?
• Which outcome concerning soil composition occurs adjacent to desert ventifact formation?
• Which adjustment occurs when alluvial river gradients decrease?
• Which feedback results when surface winds strengthen over dune fields?
