What is a Glacier?What is a Glacier?

Glaciers by definition are large masses of Glaciers by definition are large masses of snow recrystallized ice and rock debris that snow recrystallized ice and rock debris that accumulate in great quantities and begin to accumulate in great quantities and begin to flow outwards and downwards under the flow outwards and downwards under the pressure of their own weight. Glaciers form pressure of their own weight. Glaciers form when yearly snowfall in a region exceeds when yearly snowfall in a region exceeds the amount of ice and snow that melts in a the amount of ice and snow that melts in a summer. Massive amounts of material summer. Massive amounts of material accumulate in very small periods of geologic accumulate in very small periods of geologic time. time.
