Glaciology is the interdisciplinary scientific study of the distribution and behaviour of snow and ice on the earth's surface, involving contributions from physics, geology, physical geography, meteorology, hydrology and biology. It is concerned with the structure and properties of glacier ice, its formation and distribution, the dynamics of flow, and the interactions with climate. Three major types of glacier are:[Page 43]
- Ice sheets or ice caps (generally less than 50,000 km2 in area) – broad domes which submerge the underlying topography with ice radiating outwards as a sheet. The Antarctic and Greenland are examples of ice sheets with ice caps in Canada, Iceland and Norway.
- Ice shelves – floating ice sheets or ice caps which has no friction with the bed and the ice can ...
