s. The topography of ice fields is determined by the shape of the surrounding landforms, while ice caps have their own forms overriding underlying shapes.

Formation

Ice fields are formed by a large accumulation of snow which, through years of compression and freezing, turns into ice. Because of the susceptibility of ice to gravity, ice fields usually form over large areas that are basins or atop plateaus, thus allowing a continuum of ice to form over the landscape uninterrupted by glacial channels. Glaciers often form on the edges of ice fields, serving as gravity-propelled drains off the ice field which is in turn replenished by snowfall. While an ice cap is not constrained by topography, an ice field is. An ice field is also distinguishable from an ice cap because it does not have a dome-like form.
