Glaciation is basically a cyclic process in which water freezes either due to high altitude or due to low temperature as in poles.
Glaciation is the formation, movement and recession of glaciers. Glaciation was much more extensive in the past, when much of the world was covered in large, continental ice sheets. Currently, glaciers cover about 10 per cent of the world's land area (14.9 million km2). Most of this area is under two ice sheets situated near the Earth’s poles — one near the Antarctic and the other near Greenland.
Période géologique durant laquelle une région a été recouverte par des glaciers. (Les glaciations sont connues depuis le précambrien ; dans l'Europe alpine, elles ont été au nombre de quatre pendant le quaternaire : günz, mindel, riss et würm.) cette periode se traduit par abaissement de niveau de la mer.
