Discover the wonders of our earth with the Physical Geography DVD Series. This DVD looks at how glaciers have had a more profound effect on the surface of the earth than probably any other geological process. Subjects covered include: how glaciers grow from a snowflake to a mountain of ice; how glaciers move or flow; how the land is sculptured and changed by glaciers; depositional features such as kames, eskers, lateral, medial and terminal moraines and crevasses; erosional features such as U-shaped valleys, aretes, horns and fiords; why glaciers form; evidence to show that the glaciers have moved; and Alpine, Continental and Piedmont glaciers.
