Which mechanism causes meandering stream patterns in low-gradient landscapes following tectonic uplift?

💡 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.
