Which process forms predictable graded sediments within alluvial fans?

💡 Explanation

Fluvial sorting concentrates grain sizes because finer sediments will deposit further from the source due to decreased flow velocity and capacity with distance; therefore graded sediments form progressively, rather than relying on uplift rates or mineral concentrations.
