Athabasca Glacier, a snowflake requires 150â200 years to go. from fluttering out of the sky onto the icefield to melting out at the.
Glaciers Are Solid RiversA 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 eforms (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.
