A subglacial meltwater channel can be associated with which deposit?
Answer and explanation
Correct answer: Esker
The governing concept is deposition by pressurised meltwater flowing beneath glacier ice. A subglacial stream transports and sorts sand and gravel inside an ice tunnel. When the glacier retreats, the channel fill may remain as a long, winding ridge that roughly marks the former drainage route; this ridge is an esker. Therefore option B is correct. Tower karst, marine stumps, and loess plateaus form through unrelated processes.
