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.

What are glacier scratches?
Glacier scratches, also known as glacial striations, are long, parallel grooves and scratches on bedrock caused by the movement of glaciers across the surface. As a glacier moves, it carries rocks and sediment that scrape and scratch the underlying rock, leaving behind these distinctive marks. Glacier scratches provide valuable information about the direction and extent of past glaciation events.
What are striations and how do they form?
Striations are linear grooves, scratches, or ridges on a material's surface. They typically form when a harder material, such as a rock or metal, scratches or gouges a softer material, leaving visible marks. Striations can provide valuable information about the processes that formed them, such as glacial movement or tectonic plate motion.
What are glacial striations and glacial erratics?
Glacial striations are scratch marks left behind on rocks by the movement of glaciers, indicating the direction of glacial flow. Glacial erratics are large boulders that have been transported and deposited by glaciers, often far from their original source.
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.

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.
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 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.
