The rocks and pebbles embedded in the ice. When these rocks and pebbles are on the bottom surface of the glacier they are dragged over the surface of the ground, cutting into it (whether it is soil or hard bedrock) cutting grooves in and polishing that surface. Much like the grit glued to sandpaper does to a surface it is rubbed against.

Bedrock that is scratched by boulders held in the bottom of glaciers is said to be "polished and striated." This process occurs through glacial abrasion, where the boulders act like giant sandpaper, scraping and smoothing the bedrock as the glacier moves over it.
Glaciers are often compared to sandpaper because, as they move, they carry with them rocks and sediment that scrape against the underlying landscape. This abrasive action grinds and polishes the rocks beneath the glacier, similar to how sandpaper smooths surfaces. The immense weight and slow movement of glaciers enhance this erosive power, shaping valleys and creating distinctive landforms over time. This process is a key factor in glacial erosion and landscape modification.
actually glaciers move quite rapidly, they might not look like they are moving at all but in fact for their giant size they can move very quickly.
This process is known as abrasion, where the rocks carried by a glacier scrape and wear down the surface of the landscape as the glacier moves. They act like a giant sandpaper, smoothing and sculpting the underlying rock. Over time, this abrasive action helps to shape the landforms carved by glaciers.

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.

when glaciers form gravity starts pulling them and they slide over the ground and it pulls up the earth.

Abrasion erosion is similar to using sandpaper to smooth the edges of wood. In this type of erosion, particles like sand or rocks are carried by wind, water, or ice and wear down the surface of rocks or other materials over time through friction and scraping.
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.
Glacial striations are long, parallel scratches or grooves on bedrock caused by the movement of glaciers. As glaciers advance and retreat, they can pick up rocks and debris, which then act like sandpaper as the glacier moves, creating these striations on the underlying bedrock. Studying these features can provide information about the direction and extent of past glacial movement.
