← GeographyWhich outcome emerges when sediment deposition exceeds subsidence?
A)Levee formation alongside river channels✓
B)Accelerated glacial erosion in valleys
C)Increased coastal erosion from storm
D)Reduced volcanic activity in subduction
💡 Explanation
Levee formation occurs due to sediment deposition reducing channel depth; this process is vertical accretion. Competence reduction favors deposition because settling outweighs conveyance, therefore levee formation rather than channel incision emerges.
