Do glaciers scratch bedrock through the process of abrasion?
When glaciers pick up loose rocks, the rocks will act as an abrasion, scoring and abrading the land beneath as the glacier slowly moved on. You can see the scratch marks on bedrock exposed on the surface in some places.Also, boulders left isolated and strange to the area as the glacier melted and retreated are known as Glacial erratics.
What geological evidence do you have here in Alberta that glaciers once covered this province?
Glacial striations, erratic boulders, drumlins, and moraines are some geological evidence found in Alberta indicating past glaciation. These features were left behind by moving glaciers and are common throughout the province, especially in the Canadian Rockies and foothills regions.
What are the scratches left behind from glaciers called?
striations
How do water wind and ice change landforms?
Water can have a big impact on cities that are near the coast. Waves and tides hit the shore, overtime, the shore will erode,causing enviromental problems. Glaciers also affect landform. Huge glaciers that push against the land leaves marks, such as drumlins. Drumlins are teardrop shaped mounds left behind by a glacier, the direction it is pointing in is where the glacier is traveling towards.
Were lakes created when glaciers retreated?
Yes, lakes were often formed as glaciers retreated due to the depressions or basins left behind by the moving ice. These basins could fill with water from melted glacier ice, rain, or rivers, creating new bodies of water.
What is a Long scratch marks that are left behind as evidence of glaciers are called?
They are called striations.
What are the scratch marks on rocks from moving glaciers called?
The scratch marks on rocks left by moving glaciers are called glacial striations. These marks are typically parallel and indicate the direction in which the glacier was moving.
How were lakes formed in Scandinavian countries?
Because of the depressions that the glaciers left behind.

How did glaciers contribute to the formation of hills around the Lake Michigan?
As the glaciers retreated, they left rocks and boulders behind.

What are bullet striations?
The scratch marks left on the proyectile by the rifling lines of the inside of the bore (barrel).
What are the scratches left behind from glaciers called?
striations
What different kinds of material was left behind glaciers?
You must mean left begins by glaciers! Well there was big boulders for starters. And I think as they receded they left big hills and valleys called coulees! Hope this helps!
What are moraines and drumlins created by?
When glaciers advance or retreat, the sediments left behind create a moraine. Drumlins are created by the flow of glaciers that mold sediment into streamlined, elongated hills.
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.
Where are moraines found?
Moraines are found in regions where glaciers have occurred, such as mountain ranges, polar regions, and areas with high elevations. They are commonly found at the edges of glaciers or in valleys where glaciers have advanced and retreated, leaving behind deposits of rock, sediment, and debris.
