Glacial fields are formed due to a significant accumulation of snow , which over the years of compression and freezing, turns into ice . Considering the effect of gravity on ice, glacial fields usually form over large areas (above valleys or on top of a plateau ), and therefore allow the thickness of ice to form above the landscape and not be interrupted by glacial tunnels. Glaciers often form at the borders of glacial fields and serve as gravitational drains of the glacial field, which in turn is restored by snowfall . The ice field is not limited to topography, unlike the ice cap. It also differs from the ice cap in that it does not have a dome shape.
