How do glaciers erode Earth’s surface?

Answer 1

Glaciers erode Earth's surface by a process called abrasion. This process involves the grinding and scraping of rocks and sediment by the movement of the glacier. As the glacier moves, it carries rocks and sediment along with it, which scrape and grind against the underlying bedrock. This scraping and grinding action wears away the bedrock, creating valleys, cirques, and other landforms.
