Glacial grooves are caused by the ice picking up boulders and scraping them across the bedrock.
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.
Glacial striations are a result of erosion. They are scratches and grooves on bedrock caused by rocks and debris being dragged along by moving glaciers.
Yes, striations are a glacial feature caused by the erosion of bedrock as a glacier moves over it. These scratches or grooves are formed by the rocks and debris embedded in the ice scraping against the underlying rock surface.
Evidence of glacial erosion includes U-shaped valleys, striations or grooves on rocks caused by the movement of the glacier, glacial polish on rocks, and moraines (deposits of glacial till). These features indicate the past presence and movement of a glacier in the area.
Striations would most likely form on the surface of the bedrock under the glacial ice. Striations are caused by the movement of large rocks embedded in the base of a glacier scraping across the bedrock, resulting in long, parallel grooves being carved into the bedrock surface.

I assume you mean GROOVES - the Glacial Grooves were formed by the receeding glaciers.

The most well-known glacial feature on Kelleys Island would be the Glacial Grooves, located on the north side of the island. They were protected in the 1880's by deed and are generally recognized as the best examples of glacial action in the U S. There are numerous areas of glacial scratching and scouring on the island as well. If you search "Kelleys Island glacial grooves" you'll find several online pictures.
Glacial grooves form when rocks and debris trapped in the base of a moving glacier scrape along the bedrock, leaving long scratches or gouges in the surface. These grooves are typically created by the abrasive action of the glacier as it moves over the bedrock, grinding away material and leaving behind distinctive marks.
Glacial grooves are created when rocks embedded in the base of a glacier scrape the underlying bedrock as the glacier moves. The immense pressure and friction exerted by the moving glacier cause the rocks to plow into the bedrock, leaving long, parallel grooves behind. These grooves are a common feature in areas that were once covered by glaciers during the last ice age.
