Which outcome occurs when longshore drift deposits sediment?

💡 Explanation

Spit formation results because longshore drift transports sediment along the coast, depositing it where the shoreline changes direction, leading to accumulation; rather than increased offshore tsunamis or accelerated subduction, these are unrelated to sediment transport processes.
