Which type of landform is typically made from loose sediment deposition by glacial action?

The correct choice is outwash plain, which is a landform created primarily from the sediment that has been deposited by meltwater from glaciers. As glaciers retreat, they release water that carries away fine sediments and larger debris. This material is then deposited in a broad, flat area beyond the glacier, forming an outwash plain.

An outwash plain is characterized by sorting of sediments, where the larger particles settle closest to the glacier, while finer materials are carried further away by flowing water. This deposition process typically results in a landscape that is flat, with a gentle slope, and it often features features such as braided streams and various sedimentary layers.

In contrast, the other terms refer to different types of glacial landforms. Drumlins are elongated hills composed of till that are shaped by glacial movement. Kames are mound-like hills formed from sediments deposited in depressions on the glacier, and moraines are accumulations of till that accumulate at the edges of a glacier, marking its advance and retreat. Each of these landforms is related to glacial activity but does not represent the flat depositional landscape created specifically by outwash from meltwater.
