How does a glacier move like a stream why
WebOct 21, 2024 · The two main ways that glaciers erode the underlying rock are abrasion and plucking. As the thick layer of ice pushes against the underlying rock, it scrapes and polishes the rock surface. As glaciers flow, they scratch the underlying bedrock with all the rocky material they are carrying.
