i believe that you are talking about glacial striations
They are called glacial striations. These marks are created by the abrasion of rocks and sediment as a glacier moves over them, leaving parallel grooves and scratches on the surface of the rock.
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.
Glaciers are the agent of erosion that deposit irregular mounds of unsorted sediment with parallel scratches on rounded particles. This type of deposit is called a moraine, which is formed as the glacier moves and carries a mixture of different-sized sediments that get deposited when the glacier melts.
The nail is harder than the wooden ruler, causing the nail to leave scratches on the ruler's surface when it is dragged across it. Wood is a relatively soft material compared to metal, so it is easily marked by harder objects like a nail.
Vertical grooves are called "striations."

A glacier produces grooves and scratches.
Drag loose rocks over Earth's surface
"Starration " is not a word in English language. You may mean 'striation' which is one of multiple, usually parallel grooves or scratches on a material's surface

Glacier grooves are long, parallel scratches or striations on bedrock surfaces that are formed by the movement of glaciers. As a glacier flows over rocky surfaces, it picks up rock fragments and debris, which then act like sandpaper, carving long, linear grooves into the bedrock. These grooves provide valuable insight into the direction and extent of past glacial movements.
By the passing by of a glacier.
Glacial grooves are long, parallel scratches or gouges on bedrock caused by the movement of rocks and debris trapped in the base of a glacier. They are formed as the glacier advances and retreats, grinding the underlying rock surface as it moves. Glacial grooves provide valuable information about the direction and extent of past glacial movements.

glacial ice
On rocks - they are the parallel groves or scratches. Or on skeletal or cardiac muscle: they are the "strands" of the muscle.
