Is striations a glacial feature caused by erosion?
Yes, striations are a glacial feature caused by the erosion of bedrock as a glacier moves over it. These scratches or grooves are formed by the rocks and debris embedded in the ice scraping against the underlying rock surface.
What is glacial scarring?
Glacial scarring refers to the erosional marks left behind by glaciers as they move across the Earth's surface. This can include striations, grooves, and other features carved into the bedrock by the movement of the glacier. Glacial scarring is a key indicator of past glacial activity in an area and provides valuable information about the history of ice sheets and glaciers.
The gouging of bedrock by rock fragments dragged by glaciers results in?
These are known as striations. Please see the related link.
What is erosional surface?
An erosional surface is a flat or gently sloping topographic feature formed by erosion, typically by the action of water, ice, wind, or other natural processes. Erosional surfaces can reveal past geologic events and provide important clues about the Earth's history.
Is striation erosional or depositional?
Striation is typically erosional. Striations are long, narrow lines or grooves on a rock surface caused by the movement of a glacier, which acts as a powerful scouring tool that can scrape and polish the bedrock beneath it as it flows.

What is a glacial groove?
A glacial groove is a long, linear indentation or scratch in bedrock that is formed by the movement of a glacier. As the glacier flows over the rock surface, it picks up and carries rock debris, causing abrasion and carving grooves into the bedrock. These grooves provide evidence of past glacial activity and can help scientists understand the direction and extent of glacial movement.
What does glacial polish results from?
Glacial polish results from the grinding action of glaciers as they move and slide over bedrock, smoothing and polishing the surface of rocks. This process is primarily caused by the abrasion of rock particles and debris carried by the glacier against the bedrock.
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.
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 attributed to glacial abrasion?
Glacial abrasion is primarily attributed to the movement of glaciers over bedrock, which causes them to pluck and grind rock fragments from the underlying surface. The weight and pressure exerted by the glacier as it moves can also contribute to the abrasion process, wearing down the bedrock and polishing the surface over time. Additionally, the presence of debris and sediment within the glacier can act as abrasive agents, further enhancing the erosive effects of glacial movement.
What comprises an airplane runway?
A airplane runway is usually made of asphalt, although any flat surface from glacial ice, to bedrock, to concrete could work
