Document Summary

Chapter 6: describe how glaciers fit into the hydrologic cycle. When precipitation falls in cold regions such as those at the poles or at high altitudes, it may become part of a glacier. Ice sheets flow out in all directions from one center. Generally are very large and found at polar latitudes. Ice shelves exist along parts of the antarctic coastline. Sea ice is frozen seawater and includes the ice that covers the arctic ocean. An ice shelf extends from the antarctic continent and while it floats on the ocean, it remains attached to the land: describe two components of glacial movement. Plastic flow involves ductile flow within the ice due to the pressure of the overlying ice mass. Some glacial ice moves extremely slowly while others move several meters per day. These are large gaping cracks that form because the brittle ice cracks as the glacier moves over uneven terrain: relate glacial budget to two zones of a glacier.
