When glaciers move they cause erosion. Eroded materials like the fragments of rocks and boulders along with dirt are carried away by the glaciers down the slopes of mountains. Once the glaciers stop in a place, they deposit all this debris. These deposits are called glacial deposits, and the plains thus formed are called glacial or drift plains.The plains of Canada and North-Western Europe are examples of glacial plains.
