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.
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 can occur as glaciers remove loose pieces of rock or as dragged rock scratches rock underneath the glacier?
something.
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.
If you saw long scratch marks on a flat rock surface you would suspect what?
I would suspect that the rock may have been scratched by a sharp object or dragged by something with enough force to leave a mark. The scratches could also be the result of natural weathering or geological processes over time.

By the passing by of a glacier.

What are glacial striations and glacial erratics?
Glacial striations are scratch marks left behind on rocks by the movement of glaciers, indicating the direction of glacial flow. Glacial erratics are large boulders that have been transported and deposited by glaciers, often far from their original source.
What errosive effects do glaciers have on rocks?
Glaciers drag immense amount of rock debris along their bottoms. This debris will scar the underlying bedrock, and in mountains, will form U-shaped valleys, as opposed to the more typical V-shape formed from water flow. Rocks dragged and tumbled by glaciers, often show signs of scarring and may also be rounded or smoothed by constant friction with other rocks.
What animal made scratches in rock that was found in South Africa?
Scratches in rocks are typically glacial striations. These are scratch marks made by pebbles trapped in a moving ice sheet that are dragged across a base layer of rock. South Africa has been covered by ice sheets in historical times and striated rock is found in many places.

Why are the North Shore Beaches of Long Island so rocky?
What I have been told my whole life is, when the glaciers melted many, many, many moons ago all rocks were dragged to the north shore as they were stuck to the glacier.
What is the future tense of dragged?
The future tense of dragged is will drag.
