Document Summary
Water in its solid form (ice/snow: snow, ice, glaciers, frozen ground. Important inluence on climate (1st to change: transport, agriculture, water res, Penguins and polar bears don"t live in the same place. Humid mariime galciers (warm/temperate: temperature, high alitude, coastal regions, e. g. rocky mountains, new zealand. Dry coninental glaciers (cold: coninental interiors, dry atmosphere, e. g. Light absorbs red and orange and relects blue, that why a glacier gets its color. Equilibirum line: firm line (limit, inputs = outputs. Pseudo plasic low (bend not crack: weight of ice and gravity, internal deformaion. Topography: change in gradient = steep vs gentle, valley shape constrict low. Temperature: wet or dry base, wet: warmer ice deforms more + more water = faster, dry: internal deformaion, seasonal(summer vs. winter) Ice ield; regionally extensive ice accumulaion (mountain region) a: feeds several glaciers, athabasca glaciers, valley glacier e.
