How does glaciers abrade rocks?

Glaciers abrade rocks through a process called glacial erosion, where the immense weight and movement of the ice grind against the underlying bedrock. As glaciers advance, they carry with them sediment and rocks embedded in the ice, which act like tools to scrape and polish the surface of the rock beneath. This abrasion can create striations, grooves, and other features on the bedrock, gradually wearing it down over time. The combination of pressure, movement, and the abrasive materials enhances the glacier's ability to reshape the landscape.
