A glacier forms over many years when snow and ice builds up faster than it is removed. The removal of snow and ice is called ablation and includes processes such as melting and evaporation.
The study of glaciers is very important for scientists to keep track of unique variations in the Earth's climate (such as global warming) as glaciers are very sensitive to climatic changes.
