Which landscape outcome primarily relies on alluvial river progradation?

💡 Explanation

Delta formation depends on sediment deposition by the river extending outward, because progradation, a type of aggradation, results in the alluvial sediments building outward into a standing body of water; therefore deltas grow, rather than land being carved.
