← GeographyWhich morphologic outcome results on coastlines when high-sediment rivers enter seas?
A)Delta formation advances seaward expansively✓
B)Headland erosion accelerates significantly landward
C)Barrier island chains rapidly migrate inward
D)Sea stack disintegration stalls indefinitely
💡 Explanation
Delta formation occurs where a river's sediment deposition overwhelms the erosional wave action; therefore, land expands because sediment accumulation exceeds removal, rather than erosion dominating and creating landforms like headlands or stacks.
