Yes. As glaciers build up in size from long periods of snow deposition, they eventually get heavy enough to slowly move downhill. As they move (inches per year), they grind away at the underlying ground. Glacially formed valleys have a characteristic rounded shape, compared to valleys cut by a river.

Mike R is right. A glacier can erode soil and rocks. Because glaciers are so heavy, and pick up so much debris as they move (rocks, pebbles, sand, etc.) they can wear away the surface of exposed rocks, move boulders, even carve out depressions which eventually fill with water and become lakes, ponds, etc.
