Which outcome results when a delta experiences overloaded sediment deposition?

💡 Explanation

Avulsion occurs because excessive sediment deposition raises the riverbed, therefore making it energetically favorable for the river to find a steeper, shorter path to the sea, rather than continuing along the existing channel. Saltwater intrusion or chemical weathering are unrelated deposition events.
