1. How has ice-sheet erosion altered the landscape? What kinds of landscape features are produced by continental glacier deposition and recession?

2. These tables show the position (elevation) of the toe of a Northern Hemisphere valley glacier as measured yearly on September 30 during the 1970s, then again during the 1990s. Use decadal averages and annual rates of change of position to help you describe how the behavior of the glacier in the 1990s differs from that of the 1970s.
