What term describes a conical hill formed from glacial deposits?

The term that describes a conical hill formed from glacial deposits is "kame." Kames are typically formed by sediment that accumulates in depressions on a glacier's surface or at its margins. As the glacier melts, this sediment is left behind in a mound or hill, resulting in the distinctive conical shape.

In contrast, outwash refers to sediment that has been transported away from the glacier by meltwater, typically forming broad, flat plains rather than conical hills. A lake plain describes low-lying areas near lakes that consist of fine sediments deposited in calm water, typically lacking the conical form. An esker is a long, narrow ridge of stratified sand and gravel that forms beneath a glacier as meltwater deposits sediment, differing fundamentally in shape and formation process from a kame.
