← GeographyWhich mechanism causes meandering stream patterns in low-gradient landscapes following tectonic uplift?
A)Decreased channel sinuosity overcomes inertia
B)Differential erosion amplifies minor bends✓
C)Increased sediment load stabilizes banks
D)Reduced flow velocity minimizes lateral activity
💡 Explanation
When tectonic uplift occurs, the stream incises, and differential erosion occurs because flow is slightly faster at the outer bend, scouring the bank, while sediment deposits on the inner bend thereby amplifying meandering. Therefore, differential erosion causes increased meandering, rather than reduced sinuosity, stabilized banks, or minimised lateral activity which involves different erosion processes.
