New York/Canadian-Media: Glaciers are generally slow-flowing rivers of ice, under the force of gravity transporting snow that has turned to ice at the top of the mountain to locations lower down the valley — a gradual process of balancing their upper-region mass gain with their lower-elevation mass loss.
This process usually takes many decades. Since this is influenced by the climate, scientists use changes in the rate of glacier flow as an indicator of climate change.
For some glaciers around…
