The glacier abrades the bedrock and the material is carried by ice. The groove is scoured in the bedrock by the boulders carried at the bottom of the ice. Grooves have various sizes.
I assume you mean GROOVES - the Glacial Grooves were formed by the receeding glaciers.
Glacial grooves were caused by the movement of rocks and debris embedded in the base of a glacier as it moved over bedrock. The pressure and abrasion from the rocks scraping against the bedrock created the 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.

Glacial grooves are caused by the ice picking up boulders and scraping them across the bedrock.
The Glacial Grooves State Memorial, located on Kelleys Island in Lake Erie, showcases some of the most dramatic evidence of glacial activity in Ohio. These grooves, formed by the movement of glaciers over limestone, provide a striking visual testament to the region's geological history. The site is significant for understanding the impact of glacial processes on the landscape. Visitors can explore the grooves and learn about their formation and the broader effects of glaciers on the environment.
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.
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 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.

Glacial grooves are striations or scratches left on rock surfaces as glaciers move over them. The orientation and alignment of these grooves indicate the direction of the glacier's flow, as they are created by the movement of debris embedded in the glacier's base. By analyzing the pattern and angle of the grooves, geologists can determine the glacier's path and the dynamics of its movement during its advance and retreat.
Glacial grooves in Antarctica can be found on exposed rock surfaces, typically on nunataks or other high points where glaciers have flowed over the rock and carved out grooves with their abrasive action.
