What are glacier grooves?

Glacier grooves are long, parallel scratches or striations on bedrock surfaces that are formed by the movement of glaciers. As a glacier flows over rocky surfaces, it picks up rock fragments and debris, which then act like sandpaper, carving long, linear grooves into the bedrock. These grooves provide valuable insight into the direction and extent of past glacial movements.

What is the meaning of glacial grooves?

Glacial grooves are long, parallel scratches or gouges on bedrock caused by the movement of rocks and debris trapped in the base of a glacier. They are formed as the glacier advances and retreats, grinding the underlying rock surface as it moves. Glacial grooves provide valuable information about the direction and extent of past glacial movements.


What is the process for the rocks dragged by glaciers produce grooves and scratches in bedrock?

When glaciers move, they pick up rocks of various sizes. These rocks are then dragged along the bedrock beneath the glacier, causing abrasion. The rocks act like sandpaper, scraping and carving grooves and scratches into the bedrock as the glacier advances.

Where are striations?

On rocks - they are the parallel groves or scratches. Or on skeletal or cardiac muscle: they are the "strands" of the muscle.
