Which risk increases when an ephemeral stream's sediment supply decreases into a tectonically active region?

💡 Explanation

Stream incision increases because reduced the sediment supply enhances the erosive power of the stream via channel incision. Because stream incision dominates, stream capture becomes more likely due to headward erosion, rather than reduced delta lobe switching.
