Which mechanism limits sediment deposition rate within a fjord undergoing isostatic rebound post-glaciation?

💡 Explanation

When isostatic rebound occurs, a fjord's bathymetry shallows, which increases tidal current velocities due to a reduction in cross-sectional area and thus channelization; this intensification of bottom currents scours the seabed, preventing substantial deposition on specific areas. Therefore, increased tidal current scouring limits sediment deposit, rather than alterations from sediment, plant systems, or landslides, each requiring different conditions.
