  "field": "Environment",
  "definition": "Drumlins are products of the streamline (laminar) flow of glaciers, which molded the subglacial floor through a combination of erosion and deposition. A drumlin is a low, smooth, elongated-oval hill, mound, or ridge of compact till, which has a core of bedrock or drift. A drumlin usually has a blunt nose facing the direction from which the ice approached, and a gentler slope tapering in the other direction. The longest axis is parallel to the general direction of glacier flow.",
