← GeographyWhich consequence develops when increased continental weathering delivers greater alluvial sediment loads?
A)Reduced oceanic carbon sequestration rates
B)Increased coastal delta subsidence rates✓
C)Accelerated thermohaline circulation weakening
D)Higher frequency of submarine landslide events
💡 Explanation
Increased sediment supply enhances delta aggradation but compacts underlying unstable soils, accelerating Delta Subsidence because increased weight from new layers overcomes the consolidation rate; therefore subsidence risk increases, rather than other oceanographic effects.
