A process called plucking the rocks dragged by glaciers produce grooves and scratches in the bedrock?
Plucking is a process where glaciers erode the underlying bedrock by freezing onto rocks and pulling them away as the glacier moves. This action creates grooves and scratches in the bedrock, known as glacial striations. These markings serve as evidence of the glacier's movement and direction, providing valuable information about past glacial activity. Ultimately, plucking contributes to the overall shaping of the landscape by carving out features such as valleys and fjords.

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.
In a process called plucking the rocks dragged by glaciers produce grooves and scratches in bedrock?
Plucking is a process where glaciers erode bedrock by lifting and removing chunks of rock as they move. As the glacier advances, the pressure and movement cause rocks to fracture and break away from the underlying bedrock. This action creates distinctive grooves and scratches, known as striations, which provide evidence of the glacier's flow direction. Such features are commonly observed in glacial landscapes and are important for understanding past glacial activity.
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 is the gouging of bedrock by rockfragments dragged by glaciers results in?
The gouging of bedrock by rock fragments dragged by glaciers results in distinct geological features such as striations, grooves, and polished surfaces on the bedrock. These marks indicate the direction of glacial movement and can reveal the history of glacial activity in an area. Additionally, the erosion caused by this process can lead to the formation of depressions and other landforms, contributing to the overall shaping of the landscape.
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 type of glaciers are there and how do they erode the land?
glacial deposition and glacial erosion
Is Glacial striations erosion or deposition?
Glacial striations are a result of erosion. They are scratches and grooves on bedrock caused by rocks and debris being dragged along by moving glaciers.
The gouging of bedrock by rock fragments dragged by glaciers results in?
These are known as striations. Please see the related link.

What are glacial striations and glacial erratics?
Striations are "scratches" left in bedrock by glaciers. A small particle of rock, generally pebble sized or smaller, becomes entrained in the base of the glacier and dragged along the surface of the bedrock. These can often be seen on hard bedrock surfaces that are resistant to subsequent weathering after the retreat of the glacier. Erratics are large rocks that are found out of place in the landscape, i.e. not near where they were formed. They are removed from their provenance by a glacier and transported away, before being deposited in a different part or the landscape when the glacier melts.
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.
