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.
What makes glaciers act like giant sandpaper?
The rocks and pebbles embedded in the ice. When these rocks and pebbles are on the bottom surface of the glacier they are dragged over the surface of the ground, cutting into it (whether it is soil or hard bedrock) cutting grooves in and polishing that surface. Much like the grit glued to sandpaper does to a surface it is rubbed against.
The direction of movement of a glacier is best indicated by the?
alignment of grooves in bedrock
What are the grooves and scratches left in a rock by a glacier called?
Crevasses
Marked with parallel scratches or grooves?
i believe that you are talking about glacial striations
What is the process that the rocks dragged by glaciers produce grooves and scratches in bedrock is this the definition?
By the passing by of a glacier.

Glaciers often form parallel scratches and grooves in bedrock because glaciers?
Drag loose rocks over Earth's surface
Is increased erosion the cause of bedrock being left with scrapes and grooves?
is increased erosion is the wrong answer. rocks carried by glaciers is the right one
What erosional agent produces grooves and scratches?
A glacier produces grooves and scratches.

What is glacial grooves?
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.
Do glaciers cause water erosion?
Glaciers cause erosion because of the immense weight and pressure they can exude onto surfaces. Fine grains of sediment get lodged into the bottom and sides of the glacier, making it so abrasive that it scratches grooves into rock as it moves.
What causes the grooves in Kelley's Island?
I assume you mean GROOVES - the Glacial Grooves were formed by the receeding glaciers.
What caused the glacial grooves?
Glacial grooves are caused by the ice picking up boulders and scraping them across the bedrock.
The direction of movement of a glacier is best indicated by the?
alignment of grooves in bedrock
What are the grooves and scratches left in a rock by a glacier called?
Crevasses
