← GeographyWhich risk significantly increases where large-scale dam construction blocks sediment flow into a fjord?
A)Diminished delta reformation at head✓
B)Increased upwelling nutrient delivery
C)Expanded marine snow accumulation
D)Decreased turbidity current frequency
💡 Explanation
Diminished delta areas occur because sediment starvation reduces deposition at the fjord head, where rivers typically form deltas; this occurs through the mechanism of sediment transport. Without enough sediment input, deltas erode, rather than grow; therefore, less land reformation exists.
