← GeographyWhich outcome occurs when a meandering stream encounters differential weathering?
A)River cliff formation concentrates flow✓
B)Oxbow prevents further flow change
C)Braiding increases sediment deposition
D)Alluvial fans consistently build outward
💡 Explanation
River cliff formation concentrates flow because differential weathering erodes softer rock layers faster, leading to undercutting and steeper banks; stream flow shifts towards weaker sections, therefore river cliffs form rather than uniform erosion or deposition.
