Ice sheets and their impact on the landscape What happens to the land when a glacier slides over it? A series of short Vimeo tutorials from the Geographical Association about drumlins, ribbed moraine and other landforms that result from the effects of the Pleistocene ice sheets that once covered Ireland (and elsewhere).
