Which morphological change occurs when rising sea levels overwhelm a barrier island?

💡 Explanation

Rising sea levels cause landward migration via overwash of barrier islands, because increased wave energy and inundation transport sediments to the lagoon side, thereby promoting rollover; rather than stabilization or seaward growth, which need sediment supply and stability.
