TeachMeFinance.com - explain ice shelf ice shelf The term 'ice shelf' as it applies to the area of carbon dioxide can be defined as ' A sheet of very thick ice with a level or gently undulating surface. It is attached to the land on one side, but most of it is floating. On the seaward side, it is bounded by a steep cliff (ice front) 2 to 50 meters or more above sea level. Ice shelves have formed along polar coasts (e.g., Antarctica and Greenland); they are very wide with some extending several hundreds of kilometers toward the sea from the coastline. They increase in size from annual snow accumulation and seaward extension of land glaciers. They decrease in size from warming, melting, and calving'.The term 'ice shelf' as it applies to the area of Earth observation can be defined as ' A thick mass of ice extending from a polar shore. The seaward edge is afloat and sometimes extends hundreds of kilometers over the sea. Ice shelves generally fall into three categories: those fed by glaciers, those created by sea ice, and composite shelves incorporating both glacier- and sea-ice-supplied ice'.
