How does a glacier move like a stream why

WebGlaciers erode the bedrock in two major ways: (1) abrasion and (2) plucking. Abrasion is a grinding, sandpaper-like process, where rock particles of many sizes are entrained in the glacial ice and scraped against the bedrock as the … WebSep 3, 2024 · Glaciers erode the underlying rock by abrasion and plucking. Glacial meltwater seeps into cracks of the underlying rock, the water freezes and pushes pieces of rock outward. The rock is then plucked out and carried away by the flowing ice of the moving glacier ( Figure below).
