Which outcome occurs when tectonic uplift interrupts stream thalweg?

💡 Explanation

The stream's potential energy focuses downwards if uplift generates a knickpoint, creating a plunge pool through focused erosion. Rapid channel incision, or downcutting, is driven by increased kinetic energy rather than lateral erosion like meandering, because it erodes vertically.
