Glacial polishing is the process by which a glacier smooths and polishes a bedrock surface as it moves over it, causing striations and a shiny, polished appearance. This process is primarily caused by the abrasive action of rocks and sediments carried by the glacier as it moves.

How does glacial erosion and glacial deposition affect the face of the earth?
Glacial erosion shapes the land by scraping and polishing the surface, creating features like U-shaped valleys and cirques. Glacial deposition occurs when the ice melts and deposits the sediments it carried, forming landforms like moraines and drumlins. Together, these processes have significantly shaped the Earth's landscape over millions of years.
Is outwash plain a cause of erosion or deposition?
Outwash plain is a landform created by glacial deposition, where meltwater streams deposit sediments carried by the glacier. It is a result of glacial erosion upstream and deposition downstream.
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.
Is esker cause by glacial erosion?
No, eskers are not caused by glacial erosion. Eskers are long, winding ridges of sand and gravel that are formed by meltwater streams flowing in tunnels within or under glaciers. Glacial erosion refers to the process by which glaciers carve and shape the land through the movement of ice and debris.
What is a glacial trough and how does it form?
A glacial trough is a U-shaped valley carved out by a glacier as it moves downhill. It forms through a process called glacial erosion where the glacier scours and deepens the valley over time by plucking and grinding the bedrock beneath it. The vast weight and movement of the glacier cause it to scrape and shape the landscape into a distinctive U-shaped trough.

How does glacial movement cause erosion?
Yes it does.
What is the cause of world wide glacial recession?
Global warming

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 colours are polishing pads available in?
Colors of polishing pad depends on the manufacturer of the polishing pad and describes the grade (level of cut) of the polishing. Some examples are: Meguiars: Burgundy (Cutting), Yellow (Polishing), Tan (Finishing) Menzerana: White (Cutting), Orange (Polishing) Sonus: Yellow (Cutting), White (Polishing), Red (Finishing)
What is skin polishing?
skin polishing is another name for exfoliating
How do you clean eroded metal?
We can use: - mechanical polishing - chemical polishing
What is the term for all sediments of glacial origin?
Glacial deposits or glacial drift refer to all sediments of glacial origin. These deposits include materials such as till, moraines, outwash plains, and glacial erratics that are left behind by the movement of glaciers.
How are glacial valleys straightened?
Glacial valleys can be straightened through a process called glaciation. As glaciers move down valleys, they can reshape them by eroding and bulldozing material, creating straighter and smoother profiles. This process is known as glacial erosion and can result in the formation of U-shaped valleys.
