Which coastline transformation occurs with high sediment longshore drift?

💡 Explanation

Tombolo formation results from longshore drift depositing sediment between an island and the mainland, because sediment accumulation builds a connecting land bridge; therefore, tombolos form with ample sediment, rather than cave collapses or oxygen changes.
