Document Summary
Glaciers: a thick mass of ice that forms, over hundreds and thousands of years, by the accumulation, compaction, and recrystallization of snow. Hydrologic cycle - although it is part of this cycle water can be trapped in a glacier for many years. Rock cycle- because a glacier in solid form acts and interacts with the solid surface of. Glaciers have major impacts on surface features and erosion and deposition where they occur. There are several different types of glaciers; the main difference between them is where they occur and how large they are. Types of glaciers (see figures 22. 3 and 22. 4) Valley (alpine) glaciers - these are glaciers that exist in valleys of mountainous areas are called valley or alpine glaciers. Here the snow accumulate and will flow down the valley below where it forms. Piedmont glaciers form when one or more alpine glacier emerges from the valley and spreads out in a broad lobe cover some uplands and plateaus.
