glacier, any large mass of perennial ice that originates on land by the recrystallization of snow or other forms of solid precipitation and that shows evidence of past or present flow. Exact limits for the terms large, perennial, and flow cannot be set.

Glaciers begin to form when snow remains and accumulates long enough to transform into ice. Each year, new layers of snow bury and compress the previous layers. This compression forces the snow to re-crystallize, initially forming grains similar in size and shape to grains of sugar.
19 de oct. de 2023 · Glaciers are masses of snow that has been compressed into giant sheets of ice. Most glaciers were formed during the last ice age. Glaciers are massive bodies of slowly moving ice. Glaciers form on land, and they are made up of fallen snow that gets compressed into ice over many centuries.
Los glaciares son ríos de hielo que se forman por la persistencia de la nieve caída durante un largo período de tiempo, que finalmente se comprime en masas de hielo espesadas. Las clasificaciones oficiales pueden variar, pero un glaciar se considera generalmente como una masa de hielo con un área ≥100 m 2 y una profundidad de hielo de ...
