Glaciers have caused erosion??

Yes, they have.

Explanation:

Glaciers move and when they move, they take with them sediments in their path, causing erosion.

Glaciers have caused extensive erosion in all of these places except for the Appalachian Mountains. Glaciers can have an important impact on the environment due to their great erosive power. Glaciers erode the environment in three major ways: plucking, abrasion and freeze thaw. Although the process is slow, over time glaciers can completely change the scenery of a place.
