Which mechanism causes meandering stream formation across flat plains undergoing regional uplift?

💡 Explanation

When plains undergo regional uplift, streams erode vertically but also laterally; sediment deposition occurs because flow is deflected by minor irregularities, reinforcing meander bends and increasing sinuosity. Therefore, deposition reinforces deflection, rather than weathering, vegetation or oxbow formation, which don't relate to bend propagation.
