Which outcome occurs when sediment supply decreases substantially into a delta lake?

A)Increased lake water sediment infiltration
B)Decreased lakebed consolidation timescale
C)Subsidence via isostatic rebound reduction
D)Formation of a turbidity maximum decline

💡 Explanation

Reduced sediment supply lowers overburden; therefore isostatic rebound decreases sediment compaction because this uplift mechanism moderates lithostatic pressure rather than driving increased settling or turbidity.
