Glacier Definition

by Laurent Cousineau
(Montreal)

A glacier is a huge mass of ice that originated from an accumulation of snow over many years.

It moves very slowly over land and is formed when snow accumulation exceeds melting and sublimation.

Moreover, they may descend from a high valley (an alpine glacier) or spread out from a central mass (a continental glacier).

Notably, the increase in temperatures worldwide is responsible for the melting of glaciers which will in turn cause rising sea levels.

In order to stop the retreat of glaciers, we must stop climate change.
