What is the gouging of bedrock by rock fragments dragged by glaciers results?
The gouging of bedrock by rock fragments dragged by glaciers results in the formation of grooves, scratches, and striations on the surface of the bedrock. These features, known as glacial striations, provide evidence of the direction and movement of past glaciers. These marks can also help geologists determine the extent and timing of glacial activity in an area.
How did glaciers impact Minnesota?
They leave behind glacial lakes, striations, and river valleys creating the Minnesota landscape there is today.
What are the scratches left behind from glaciers called?
striations
Marked with parallel scratches or grooves?
i believe that you are talking about glacial striations
Is evidence of the past existence of glaciers?
U-shaped valleys, erratic boulders and rocks, modern soils, glacial striations on bedrock, the Great Lakes in the United States, extinction events, and massive redistribution of soils and rock.

What clues would you look for to determaine if you were in an area that was oncee covered by glaciers?
Many topographical features may be the result of glaciers. Lakes, sharp ridges on mountains, and glacial striations are some examples of these.
What are glacial striations?
It was a continental drift .
What are the scratches left behind from glaciers called?
striations
What agent of erosion is striations?
glacial erosion
Is Glacial striations erosion or deposition?
Eroison
What are very large striations called?
Glacial Cracks
What is the evidence for PAST glaciations?
Evidence for past glaciations includes glacial landforms like moraines and drumlins, glacial striations on bedrock caused by the movement of glaciers, and the presence of glacial erratics, which are large rocks transported by glaciers and deposited in areas where they are not native. Additionally, the study of ice cores from polar ice sheets provides a record of past climate conditions and the extent of glaciations.

What is a Long scratch marks that are left behind as evidence of glaciers are called?
They are called striations.
