glacial

adj. of or covered with glaciers or large masses of ice; caused by glaciers; cold, icy, frigid; unfriendly, icily indifferent; extremely slow

"Glacial" and "Glaciation" redirect here. For the geological periods, see Ice Age. For the story by Alastair Reynolds, see Glacial (short story). A glacier is a large, slow moving river of ice, formed from compacted layers of snow, that slowly deforms and flows in response to gravity. Glacier ice is the largest reservoir of fresh water on Earth, and second only to oceans as the largest reservoir of total water. Glaciers cover vast areas of polar regions but are restricted to the highest mountains in the tropics. Elsewhere in the solar system, the vast polar ice caps of Mars rival those of the Earth.
