Which outcome occurs when debris flow deposits sediment?

💡 Explanation

The deposition by debris flow leads to creation of an alluvial fan, because sediment diverges from a channel and spreads outward via **sediment deposition**, therefore accumulating material in a semi-circular shape rather than incising vertically via narrow rivers.
