Characteristics of water contained in glaciers The glaciers are increasingly heard, and all thanks circularness effect, which causes a reduction in their volume. Glaciers are formed from the conversion of eternal snow decks in glacial ice. Incorporates the snow under the influence of prevailing temperature, high humidity in the air and under the influence of pressure indulgence layers reduces its volume, partially crystallizes and transforms gradually, first in the furn, and then on ice and glacial firepower Glaciers are formed where the terrain favors the accumulation of large amounts of snow, and is too cold to snow stopping all collected during the year. Such conditions exist primarily in the Arctic zone and the high mountains in all climate zones, above the limit of perpetual snow. It is the height above which there is in the course of the year too low temperature to the entire stock of accumulated snow in any given year could dwindle. The course of the boundary on the ground depends on the climate and topography. It reaches a maximum in the zone microdensitometer in miswritten dry climates, because of the high temperature at the foot of the mountains and scant rainfall.
