outwash
This term is primarily a technical geological descriptor. As a noun, it refers to the specific debris field created by glacial meltwater, evoking an image of vast, porous plains of sand and gravel. It is distinct from till, which is deposited directly by ice rather than by water.
When used as a verb, the word describes the active process of erosion and transport. It carries a connotation of cleansing or stripping away, often used in environmental science to describe how water removes minerals or pollutants from a soil profile.
