The ice also flows down valleys extending from the icefield, pulled by gravity just as river water is, but much more slowly, moving downhill between 15 m and 125 m a year. In the. Athabasca Glacier, a snowflake requires 150â200 years to go. from fluttering out of the sky onto the icefield to melting out at the.
Simply stated, a glacier is a large, slow-moving mass of ice. While there are many types of glaciers, they can be divided into two categories: alpine and continental. Alpine glaciers are found in a mountainous region and flow down valleys.Continental glaciers are dome-shaped glaciers that flow away from a central region and are largely unaffected by the landâs topography. The Greenland and Antarctic ice sheets are examples of continental glaciers.Smaller masses of ice, called ice caps, are also considered continental glaciers. Alpine glaciers are further classified by their shape as well as the surface they flow onto.lpine glaciers flow down valleys, and continental glaciers flow outward in all directions from a central point. Glaciers move by two mechanisms: internal deformation and sliding. Internal deformation occurs when the enormous mass of a glacier causes it to spread out due to gravity.
