Which geographical change accelerates when fjord sill depth decreases?

💡 Explanation

Decreased sill depth enhances turbulent mixing because increased tidal flow velocity over the sill causes turbulent overturn, therefore promoting re-oxygenation, rather than strengthening stratification because deeper sills trap denser water.
