← GeographyWhich outcome during glacial retreat facilitates esker formation?
A)Subglacial meltwater channel sediment deposition✓
B)Isostatic rebound increases river gradient
C)Thermokarst lake expansion accelerates erosion
D)Postglacial loess deposition obstructs drainage
💡 Explanation
Eskers form due to sediment deposition within subglacial meltwater channels because pressurized water flow deposits material progressively, therefore creating long sinuous ridges, rather than other outcomes related to postglacial modification.
