What are the grooves and scratches left in a rock by a glacier called?
They are called glacial striations. These marks are created by the abrasion of rocks and sediment as a glacier moves over them, leaving parallel grooves and scratches on the surface of the rock.
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.
Which agent of erosion deposits irregular mounds of unsorted sediment with parallel scratches on rounded particles?
Glaciers are the agent of erosion that deposit irregular mounds of unsorted sediment with parallel scratches on rounded particles. This type of deposit is called a moraine, which is formed as the glacier moves and carries a mixture of different-sized sediments that get deposited when the glacier melts.
Why are there scratches on a wooden ruler when a nail is used to scratch it?
The nail is harder than the wooden ruler, causing the nail to leave scratches on the ruler's surface when it is dragged across it. Wood is a relatively soft material compared to metal, so it is easily marked by harder objects like a nail.
What are vertical grooves called?
Vertical grooves are called "striations."
What is the name of the parallel scratches or grooves that mark something?
Striations
What are the grooves and scratches left in a rock by a glacier called?
They are called glacial striations. These marks are created by the abrasion of rocks and sediment as a glacier moves over them, leaving parallel grooves and scratches on the surface of the rock.
What erosional agent produces grooves and scratches?
A glacier produces grooves and scratches.
Glaciers often form parallel scratches and grooves in bedrock because glaciers?
Drag loose rocks over Earth's surface
What is the meaning of starration?
"Starration " is not a word in English language. You may mean 'striation' which is one of multiple, usually parallel grooves or scratches on a material's surface
What are parallel grooves?
stria
What are glacier grooves?
Glacier grooves are long, parallel scratches or striations on bedrock surfaces that are formed by the movement of glaciers. As a glacier flows over rocky surfaces, it picks up rock fragments and debris, which then act like sandpaper, carving long, linear grooves into the bedrock. These grooves provide valuable insight into the direction and extent of past glacial movements.
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.
What is the meaning of glacial 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.

U-shaped valleys and parallel grooves in bedrock are characteristics of erosion by?
glacial ice
Where are striations?
On rocks - they are the parallel groves or scratches. Or on skeletal or cardiac muscle: they are the "strands" of the muscle.
