Which outcome occurs when sediment load exceeds stream capacity at mountain base?

💡 Explanation

Alluvial fan deposition occurs because sediment sorting reduces transport capacity where a mountain stream exits the steep slope; therefore, the reduced energy causes abrupt deposition rather than continued channelized downcutting seen when stream retains capacity.
