What are glacier scratches?
These marks are called striae and are the parallel marks left on the bedrock when rocks entrained in the glacier scrape along the glacier's base..These are part of the origin of the features called moutonne roches = rock sheep. Which were NOT your usual merino, but were the nick name given to judges wigs, which, when lying on the bench, had similarities with the geological features; the shape being similar, and the striae resembling the marks left on the rock. At least according to some authorities such as Holmes.
What are striations and how do they form?
When a Glacier moves over an area of soft or hard rock it may have smaller stones underneath it, these small stones scratch into the larger rock making the Striations. They show which direction the Glacier travelled in.
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 is the name of small waves formed on the surface of sand by the action of water or wind?
I think the answer is called ripple marks
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.
What is a Long scratch marks that are left behind as evidence of glaciers are called?
They are called striations.
What are striations how are they formed?
As glaciers move over Earth's surface, the ice acts like sandpaper. The scratch marks that are visible when the ice melts are called striations.
What are long scratch marks that are left behind on glaciers?
Long scratch marks on glaciers are known as striations. They are formed by the movement of glacial ice over bedrock, where embedded rocks and debris scrape the surface, creating grooves or scratches. These marks indicate the direction of glacial flow and provide valuable information about past glacial activity and the geological history of the area.
How did wegner use climate evidence to support his hypothosis?
In Africa there are scratch marks that could only have been caused by glaciers but Africa is by a hot place by the equate so once it was colder there

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.
Do you know what kind of animal could leave bear scratch marks on a tree?
Yes, bears are known to leave scratch marks on trees.
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.
can my dog leave scratch marks?
It certainly is possible to scratch it, but this stand is scratch resistant and won't scratch easily - but almost nothing out there is really "scratch proof". Generally, no it won't scratch easily.
What color is a fingernail scratch on the skin?
Most scratches from fingernails leave red marks where the scratch occurred.
What is it called glaciers leave marks on rocks?
When glaciers move over rocks, they can leave behind scratches and grooves known as "glacial striations." These marks are formed by the abrasion of rocks and sediments embedded in the glacier's base against the underlying bedrock. This process provides valuable information about the direction of glacial movement and the history of the landscape.
