Which outcome occurs when tectonic uplift limits fluvial downcutting alluvial valleys?

💡 Explanation

Entrenched meanders form because the river downcuts rapidly through the uplifted alluvial valley floor using channel incision. Because downcutting occurs, rather than lateral erosion, steep-sided canyons are created, rather than broad floodplains from meander evolution.
