← GeographyWhich mechanism causes the meandering pattern observed in mature lowland streams?
A)Differential erosion amplifies channel bends✓
B)Base level rise reduces stream gradient
C)Tectonic uplift increases incision rate
D)Vegetation removal decreases bank stability
💡 Explanation
When a stream flows over easily eroded sediment, differential erosion occurs because slightly deeper sections experience greater flow and therefore erode faster, amplifying initial bends that increase path length and meander. Therefore, differential erosion causes meandering, rather than base level changes, uplift, or vegetation changes which alter the overall channel morphology through different processes.
