Which outcome occurs when a proglacial lake rapidly drains due to ice dam collapse?

💡 Explanation

When a proglacial lake drains rapidly, catastrophic discharge increases sediment load and flow velocity because the sudden release of water erodes channels and deposits sediment downstream. Therefore, braided stream systems develop, rather than terraces, active layers, or varves which require different environmental forcing conditions.
