Which outcome occurs when floodplains experience increased sediment deposition?

💡 Explanation

Alluvial terrace formation accelerates due to increased sediment deposition via aggradation, because vertical accretion builds the floodplain higher, therefore distinct terraces form rather than simpler floodplain expansion given equilibrium conditions.
