← GeographyWhich morphological change results when waves deposit sediment?
A)Formation of a barrier island✓
B)Increased coastal upwelling velocity
C)River delta subsidence increases sharply
D)Glacial isostatic rebound accelerates onshore
💡 Explanation
Barrier islands form due to longshore drift, where waves transport and deposit sediment parallel to the coast; forming elongated landforms because sediment accumulation outpaces erosion over time, therefore barrier islands appear, rather than changes in upwelling, delta subsidence or glacial rebound.
