Glaciers are categorized by their morphology, thermal characteristics, and behavior. Alpine glaciers form on the crests and slopes of mountains.A glacier that fills a valley is called a valley glacier, or alternatively an alpine glacier or mountain glacier. A large body of glacial ice astride a mountain, mountain range, or volcano is termed an ice cap or ice field.

Like great rivers of ice, glaciers have sculpted mountains and carved out valleys. They continue to flow and shape the landscape in many places today.

Glaciers: How do they form and how do they move?

What is a Glacier? A glacier is a slowly flowing mass of ice with incredible erosive capabilities. Valley glaciers (alpine glaciers, mountain glaciers) excel at sculpting mountains into jagged ridges, peaks, and deep U-shaped valleys as these highly erosive rivers of ice progress down mountainous slopes.

Glaciers definition, an extended mass of ice formed from snow falling and accumulating over the years and moving very slowly, either descending from high mountains, as in valley glaciers, or moving outward from centers of accumulation, as in continental glaciers. See more.

Glaciers are classifiable in three main groups: (1) glaciers that extend in continuous sheets, moving outward in all directions, are called ice sheets if they are the size of Antarctica or Greenland and ice caps if they are smaller; (2) glaciers confined within a path that directs the ice movement are called mountain glaciers; and (3) glaciers that spread out on level ground or on the ocean at ...

Glaciers moving natural accumulations of ice of atmospheric origin on the earth?s surface. Glaciers are formed from solid precipitation in areas in which more precipitation is deposited during the year than melts and evaporates: Thus, glaciers consist of an alimentation area and an ablation area, separated by the alimentation line (a line on the ...

Glaciers are the largest moving objects on earth. They're massive rivers of ice that form in areas where more snow falls each winter than melts each summer. Their scale is truly gargantuan -- the glaciers that form the ice cap covering Greenland hold enough ice to encase the entire Earth to a ...

Glaciers are made up of fallen snow that, over many years, compresses into large, thickened ice masses. Glaciers form when snow remains in one location long enough to transform into ice. What makes glaciers unique is their ability to move.

Glaciers make cirques by grinding existing valleys into a rounded shape with steep sides. This well-formed cirque in Glacier National Park contains a meltwater lake, Iceberg Lake, and a small cirque glacier that produces the icebergs in it, both hidden behind the wooded ridge.
