← GeographyWhich 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.
