Which outcome results when persistent longshore drift encounters a natural coastal indentation?

💡 Explanation

A spit forms because longshore drift carries sediment along the beach; as it reaches the bay's opening, decreased energy causes deposition called coastal progradation. Therefore a spit extends partially across, rather than increased wave diffraction or fluvial deposition at stream entries.
