← GeographyWhich outcome commonly follows rapid sediment deposition into a glacial lake?
A)Formation of laminated lake deposits✓
B)Accelerated thermohaline circulation shutdown
C)Establishment of a stratified anoxic zone
D)Decreased rate of esker sedimentation
💡 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.
