* Glaciers erode and transport sediment: As glaciers move, they carve out the landscape, picking up rocks, soil, and other debris. This sediment is then transported within the glacier.

* Glacial till: The sediment deposited by a glacier is called glacial till. This material is often unsorted and contains a mix of different sizes of rock fragments.

* Glacial landforms: The deposition of sediment by glaciers creates distinctive landforms, such as moraines, outwash plains, and drumlins. These landforms are important indicators of past glacial activity.

* Glacial flour: Fine sediment, called glacial flour, is ground up by the glacier and can be carried by meltwater to lakes and rivers, giving them a milky appearance.

Therefore, sediment plays a vital role in the formation, movement, and influence of glaciers on the landscape.
