Which outcome commonly follows rapid sediment deposition into a glacial lake?

💡 Explanation

The formation of laminated lake deposits (varves) occurs, because graded bedding results from flood events; this layering is due to seasonal Meltwater Pulse. Therefore, varves record past sediment load, rather than deep-water stratification or altered esker dynamics.
