← GeographyWhich mechanism primarily governs sediment deposition patterns in the deepest sections of fjord environments?
A)Turbidity currents carrying sediment offshore✓
B)Wave action redistributing coastal deposits
C)Glacial till deposited directly on the seabed
D)Tidal currents winnowing finer particles
💡 Explanation
When unstable sediment accumulates on steep fjord slopes, gravitationally driven turbidity currents occur transporting sediment down-slope due to density differences, depositing along the deepest basins far from shore. Therefore, turbidity currents dominate patterns, rather than wave action, glacial action, or tidal currents which have limited influence at those depths.
