Correct Answer: A
Solution :[a] End moraines or terminal moraines, are ridges of unconsolidated debris deposited at the snout or end of the glacier. They usually reflect the shape of the glacier's terminus. A medial moraine is found on top of, and inside an existing glacier. Medial moraines are formed when two glaciers meet.
