The [glaciology] tag concerns all forms of snow and ice on Earth and in space. And the marks left by ancient glaciers.

The tag concerns all forms of ice and snow, frozen water, on earth or in space. The field of glaciology covers aspects such as materials science, chemistry, physics and climatology to understand the behaviour, composition, processes and existence of snow and ice. The International Association of Cryospheric Sciences (IACS) for example, provide five areas of snow and ice research to cover the field Snow and Avalanches, Glaciers and Ice sheets, Marine and Freshwater Ice, Cryosphere, Atmosphere and Climate, Planetary and other Ices of the Solar System,
