Final answer:
Glacial drift is the term used for any sediment transported by glaciers, icebergs, or meltwater. It encompasses a variety of materials and plays a significant role in shaping geological features.
Step-by-step explanation:
Any sediment carried by ice, icebergs, or meltwater is called glacial drift. Glacial drift includes all material of glacial origin found anywhere on land or at sea, including sediment that was carried by ice, icebergs, or meltwater. Glaciers and ice sheets, like those in Antarctica or Glacier National Park, move slowly over land, eroding and accumulating sediment, which they can deposit in new locations as they melt.
This process of transporting sediment is crucial in shaping various geological features and forming sedimentary rocks. It often includes a range of materials from large boulders to fine silt. When geologists examine sediment left by glaciers, they match its geochemical signature to the rocks from which it originated to determine the past locations and movements of glacier edges.
