Which outcome occurs when sediment load overwhelms stream competence after intense uplift?

💡 Explanation

Alluvial fans form because rapid uplift causes sediment load to increase substantially, and deposition occurs along stream channels, exceeding stream competence, spreading outwards. Therefore, fan deposition characterizes this environment rather than channel incision because streams cannot carry huge amounts of sediment.
