Fluvioglacial processes: meltwater, erosion, transportation and deposition
Meltwater flowing from glaciers acts like a powerful river. It erodes rock, carries sediment, and deposits it to build distinctive landforms beyond the ice.
Real World
The outwash plain (sandur) south of Iceland's Vatnajökull glacier was deposited by powerful meltwater rivers carrying sorted sediment from beneath the ice — these plains are so flat they are used as landing strips.
Exam Focus
Contrast fluvioglacial sediment (sorted, stratified) with glacial till (unsorted) — examiners frequently award a mark specifically for this distinction.
