Which consequence results when mountain streams erode floodplains?

💡 Explanation

Increased stream capture occurs because **headward erosion** increases drainage area of steeper rivers; therefore, river systems compete rather than contributing independently to the trunk stream, leading to escalating capture because headward erosion expands quickly.
