True or false, Glaciers gouge and scratch bedrock through the process of abrasion.
1 answer
True. Glaciers can gouge and scratch bedrock through the process of abrasion. As glaciers move, they carry large amounts of sediment and rocks in their ice. These particles act as tools, scraping and grinding against the bedrock beneath the glacier. Over time, this abrasion can create grooves, scratches, and polish the bedrock surface.
