Which outcome occurs when excessive sediment accumulates behind a coastal barrier due to substantial longshore drift?

💡 Explanation

Tombolo formation stems from material transportation via longshore drift; because sediments build behind an obstacle, a land bridge forms. Consequently, an island connects to the mainland nearby, rather than the acceleration of crustal uplift, turbidity currents or bypass events.
