definition	Scratches or gouges cut into bedrock by glacial abrasion. Glacial striations are usually multiple, straight, and parallel, representing the movement of the glacier using rock fragments and sand grains, embedded in the base of the glacier, as cutting tools. Large amounts of coarse gravel and boulders carried along underneath the glacier provide the abrasive power to cut trough-like glacial grooves, and finer sediments also in the base of the moving glacier further scour and polish the bedrock surface, forming a glacial pavement.
