← GeographyWhich outcome occurs when sediment load overwhelms a delta's outflow to a lake?
A)Advancing delta lobe formation✓
B)Formation of submerged aquatic vegetation
C)Decreased lake water residence time
D)Pelagic food web stabilization
💡 Explanation
Advancing delta lobes form due to sediment deposition overwhelming the outflow capacity, because aggradation pushes distributary channels forward; therefore, new land emerges rather than plant growth or water changes, because it's controlled by deposition rates.
