Question

Quizplus · Accepted Answer

Glacial flour is a sediment type that is produced by the grinding action of glaciers on bedrock. As glaciers move, they pick up rocks and other sediments, which are then ground against the bedrock as the glacier flows over it. This grinding action produces very fine particles of sediment, which are carried by streams and rivers downstream from the glacier. This sediment is often a distinctive light gray color and is known as glacial flour. Nunataks, stoss, ablation, and névé are not sediment types, but rather terms that refer to other aspects of glaciation.
