Which erosional effect of glaciation results in much of Canada having little to no soil today?

The erosional effect of glaciation that results in much of Canada having little to no soil today is the removal of materials. During glaciation, immense glaciers moved across the landscape, scraping away rock and soil in a process known as glacial erosion. This movement not only abrades the underlying bedrock but also transports sediment and soil away from the area. As glaciers advance and retreat, they can scour away much of the pre-existing soil layer, leaving behind a landscape that is either bare rock or covered with only a thin layer of sediment.

In many parts of Canada, particularly in regions that experienced intense glacial activity, this process has led to extensive areas with poorly developed soils or areas completely devoid of soil. The impact of glaciation on the soil profile in Canada is significant, as many locations do not have enough accumulated soil material to support extensive vegetation or agriculture. Understanding this aspect of glaciation helps explain the character of Canadian landscapes and the challenges in land use and agriculture in glaciated regions.
