The ablation zone is located in the lower area of a valley glacier and around the outer limits of an ice sheet. Another prominent line on a glacier is the firn line. This is where the edge of older snow blankets extend beyond the previous years snow blanket line. After snow is gathered in the accumulation zone the glacier will transfer it to the ablation zone, as it does it converts it to glacial ice. Great lengths are required to accomplish these changes in the glacier.
Glaciers can be found in a variety of locations, they virtual exist on every continent .
Mountainous maritime localities like Norway, Alaska, and the Andes or continental high mountain terrain like the Alps and the Himalaya are the most ideal conditions for the formation of glaciers at present. Conclusion Glaciers are important to study, both their present day impact as well as their past directly affect human society. By interpreting historical climatic records encased within glaciers, scientists can put themselves in a better position to predict what may happen in the future. The more we know about glaciers and how they work the more useful they become. Glacial Environments .
