Its shape is mainly determined by the dynamics of its outward flow. There are only two ice sheets in the modern world, on Greenland and Antarctica; during gla...

| Summary: | Ice sheet: a mass of land ice, continental or sub-continental in extent, and thick enough to cover most of the underlying bedrock topography. Its shape is mainly determined by the dynamics of its outward flow. There are only two ice sheets in the modern world, on Greenland and Antarctica; during glacial periods there were others. Ice shelf: a thick, floating slab of freshwater ice extending from the coast (originating as land ice). Nearly all ice shelves are in Antarctica. Ice sheets (total) |
