Document Summary
Glacier: thick mass of ice that originates on land from the accumulation, compaction and recrystallization of snow: glaciers are agents of erosion that move and in that process transports sediment from one area to another. Ice sheet: a very large thick mass of glacial mass that flows outward in all directions from one or more of the accumulation centres. Currently only two on earth (called continental ice sheets) Antarctic ice sheet: ice shelves: large flat masses of floating ice that extend seaward from the coast but remain attached to the land along one or more sides. Valley (alpine) glaciers: a glacier confined to a mountain valley which was previously a stream valley. Can be thought of as a stream of ice bounded by rock walls. Ice caps: a mass of glacial ice covering a high upland or plateau and spreading out radially, ice stream.
