Final answer:
The term for all material moved by glaciers is 'glacial till', which includes a range of sediment sizes from fine silt to large boulders. This poorly sorted material is left behind when glaciers retreat, impacting landscapes worldwide.
Step-by-step explanation:
The general term for all material moved by glaciers is glacial till. This material encompasses all kinds of debris from fine silt to large boulders that are picked up and transported by the moving ice. As glaciers from areas like Glacier National Park advance, they grind underlying rock, creating a variety of sediments. When the ice melts, this material is deposited, often in a poorly sorted conglomerate, known as till. Sediments that are slightly more sorted, having been distributed by meltwater, are referred to as outwash.
Examples of landscapes shaped by glacial action include the majestic mountains of Glacier National Park, carved by both past and present glaciers, and the varied topography of places like Cape Cod, which were also formed by glacial activity. The impact of glaciers is not limited to any one continent or country, as their historical presence is evidenced by geological features found across the globe.
