IPA: /ˈaʊtˌwɑʃ/
KK: /aʊtˌwɑʃ/
Material like sand and gravel that is carried away by water from a melting glacier and deposited elsewhere.
The outwash from the glacier created a flat area filled with sand and gravel.
Outwash → It is formed from "out-" (meaning outside or away) and "wash" (from Old English "wæscan", meaning to cleanse or wash). The word "outwash" refers to the process of water washing away materials from a glacier or other source, moving them outside or away from the original location.
Think of water moving 'away' ('out-') to 'cleanse' ('wash') the area, which helps you remember that outwash refers to materials washed away from a source.
