← GeographyWhich mechanism significantly increases sediment deposition rates at deep fjord basins with seasonal meltwater influx?
A)Flocculation caused by salinity gradient.✓
B)Osmosis driven by freshwater outflow.
C)Coriolis effect disrupting turbidity currents.
D)Halocline formation blocking river discharge.
💡 Explanation
When meltwater influx increases, rapid deposition occurs because the fresh water creates a strong salinity gradient, inducing flocculation forcing suspended particles to bind together and sink quicker. Therefore, flocculation raises sediment deposition, rather than osmosis related effects, Coriolis, or halocline blocking, which have differing mechanisms.
