Which process primarily controls sediment deposition and layering at the head of a fjord?

💡 Explanation

When river water discharges into sediment-laden fjord water, turbidity currents form because the sediment-water mixture has higher density, leading to density stratification controlling sediment layering. Therefore, turbidity current density stratification explains observed sediment structure, rather than other ocean processes that influence overall water circulation.
