Abstract:
A Glacier is a perennial body of ice and snow, in which ice from a higher elevation is transported to a lower elevation. The movement of the ice is always from the upper part of the glacier towards the lower end. Glaciers are basically the ice mountain but unlike typical mountains these mountains can move.
Glaciers are made up of fallen snow that, over many years, compresses into large and thick ice masses. Glacier are formed when snow remain in one place before transforming into fern and then ice. Due to sheer mass, glaciers flow like very slow rivers. Presently, glaciers occupy about 10 % of the world's total land area with most located in Polar Regions like arctic and Antarctica.
