Which outcome occurs when a newly formed barrier island restricts lagoon water exchange?

💡 Explanation

Salinity becomes more extreme because restricted water exchange causes increased evaporation and reduced tidal flushing, a positive feedback mechanism. Therefore lagoon salinity varies widely, rather than stable conditions from open ocean flux.
