Which landforms are commonly associated with glacial till as a parent material?

Glacial till is an unsorted mixture of various sediment sizes deposited directly by glacial ice. This characteristic leads to the formation of specific landforms that are commonly associated with glacial processes. Drumlin and ground moraine are two such landforms.

Drumlins are streamlined, elongated hills formed from the accumulation of glacial till that has been shaped by the movement of the glacier itself. They often appear in clusters and are oriented in the direction of the glacier's flow. Ground moraine, on the other hand, consists of the debris left behind by a glacier as it retreats, creating a relatively flat or gently undulating surface covered with a mix of clay, silt, sand, and larger stones.

Understanding the association between these landforms and glacial till helps in identifying past glacial activity and provides insight into soil formation processes in glaciated regions. Other options do not pertain to glacial processes; for example, floodplains and deltas are formed by river action, while alluvial fans are associated with sediment deposition from flowing water, which are distinctly different from processes involving glacial till.
