Which outcome results when rapid sediment accumulation blocks tributary inflow into a lake?

💡 Explanation

A lacustrine delta forms because sediment accumulation at the tributary mouth overwhelms the lake processes, via a process called delta formation. Because a delta forms at a river entering a lake, therefore deposition concentrates there, rather than causing general sediment mixing.
