Which process limits stream downcutting during continental uplift?

💡 Explanation

Base level is the lowest point to which a stream can erode; regional uplift causes increased downcutting until a new base level is achieved. Therefore, base level stabilization limits further incision, rather than variations caused by isostatic rebound or stream capture.
