What type of soil texture is typically associated with outwash?

Outwash refers to sediments deposited by meltwater from glaciers, and these deposits typically consist of well-sorted materials, primarily composed of sand and gravel. This texture forms because the strong flow of meltwater can transport coarser particles over distances, where they are eventually deposited as the water slows down in energy.

The predominance of sandy and gravelly materials in outwash aggregates is indicative of their transport and deposition mechanisms, primarily influenced by the hydrodynamic processes at play during glaciation. The characteristics of sandy and gravelly textures allow for good drainage and aeration, making them distinct from other soil textures that hold more moisture, such as clay or silty soils.

In comparison to the other soil texture types listed, sandy and gravelly soils are much more common in outwash deposits due to the original processes of glacial erosion and transport. Thus, this choice accurately reflects the typical soil texture associated with outwash environments.
