GEOLOGY

Detailed explanation-1: -drumlin, oval or elongated hill believed to have been formed by the streamlined movement of glacial ice sheets across rock debris, or till . The name is derived from the Gaelic word druim (“rounded hill, ” or “mound”) and first appeared in 1833. Drumlin. Related Topics: continental landform rock drumlin hill glaciation.

Detailed explanation-2: -A drumlin is a long, low hill of sediments deposited by a glacier. Drumlins often occur in groups called drumlin fields. The narrow end of each drumlin points in the direction the glacier was moving when it dropped the sediments. An esker is a winding ridge of sand deposited by a stream of meltwater.

Detailed explanation-3: -Drumlins are hills of sediment (generally a quarter of a mile or more in length) that have been streamlined by glacier flow. Thus, they are often elongated. They often occur together in fields, some with as many as several thousand individuals.

Detailed explanation-4: -It includes deposition of glaciofluvial sediment in cavities scoured into a glacier bed by subglacial meltwater, and remnant ridges left behind by erosion of soft sediment or hard rock by turbulent meltwater.

Detailed explanation-5: -Glacial till is the sediment deposited by a glacier. It blankets glacier forefields, can be mounded to form moraines and other glacier landforms, and is ubiquitous in glacial environments.
