glaciers

dear Vanities, A glacier is a large accumulation of many years of snow, transformed into ice. This solid crystalline material deforms (changes) and moves. Glaciers, also known as "rivers of ice," actually flow. Gravity is the cause of glacier motion; the ice slowly flows and deforms (changes) in response to gravity. A glacier molds itself to the land and also molds the land as it creeps down the valley. Many glaciers slide on their beds, which enables them to move faster. Rock that falls onto the glacier's surface is incorporated into the glacier and erodes the bed, forming sediment. The glacier and its load of rock debris flow down-valley. A glacier discharges snow from its accumulation area in the same way a stream discharges water from its watershed. Sometimes, in cold climates with a lot of snow like Alaska, glaciers flow all the way down to sea level. These glaciers carve fjords and make icebergs. At the glacier's face, ice which has been melting, fracturing, and has been battered by the sea breaks off as icebergs - a process called calving which balances the flow of ice from behind. These details and some more are available in the sites http://www.asf.alaska.edu/educational/glacier_power/how_move/how_move_begin.html http://www.northstar.k12.ak.us/schools/joy/denali/OConnor/move.html http://www.wisegeek.com/how-do-glaciers-move.htm If you go through all these sites you can find out all that you want to know. All the best

when the ice melts in the north then a movement is been created thats just my idea on it...

I don't really know how it moves. I think it just does or the wind and the current just moves it somehow.
