Which consequence occurs after long-term barrier island migration?

💡 Explanation

As drift patterns shift barrier islands landward, freshwater input decreases because `sediment starvation` reduces exchange with the mainland. This leads to higher salinity, therefore increased lagoon salinity is observed, rather than ocean current changes.

• A river exits a steep canyon onto a plain, forming an alluvial fan; which change would accelerate the fan's progradation?
• Which landform characteristic results when wave refraction focuses energy?
• Which effect influences deep ocean currents due to density differences from brine rejection during sea ice formation?
• Which outcome occurs when a saturated fault experiences creeping?
• What outcome increases downwind when longshore drift slows?
• What wave action gradually causes toppling of coastal sea stacks?
