glaci-

(Latin: ice)

conglaciation (s) (noun), conglaciations (pl)
1. The act or process of changing into ice, or the state of being converted to ice.
2. A freezing; a congelation; also, a frost.
deglaciation (s) (noun), deglaciations (pl)
1. The gradual melting away of a glacier from the surface of a landmass.
2. The removal of land ice from an area; usually by melting.
fluvioglacial (adjective), more fluvioglacial, most fluvioglacial
Pertaining to streams flowing from a glacier, or to deposits laid down from glacial streams.
glacial till
The mass of rocks and finely ground material carried by a glacier, then deposited when the ice melted.

The process creates an unstratified material of varying composition.

glacial, glacially
1. Relating to, referring to, or derived from a glacier.
2. Pertaining to those geological intervals characterized by cold climate conditions and advancing ice sheets and caps.
3. Suggestive of ice, extremely cold; frigid: such as, a glacial wind.
4. Devoid of warmth and cordiality: "He had a glacial handshake."
5. Coldly imperturbable: "She maintained a glacial calm despite all of the confusion."
6. A reference to a purity marked by the tendency to readily solidify in the form of ice-like crystals; such as, glacial acetic acid.
7. Relating to, or being any of those parts of geologic time from Precambrian onward when a much larger portion of the earth was covered by glaciers than at present.
8. Suggestive of the very slow movement of glaciers: "The congressional progress on the bill has been glacial."
glacialist, glacial geologist
1. Someone who studies geological phenomena involving the action of ice; especially, of glaciers.
2. Anyone who attributes the phenomena of the drift, in geology, to glaciers.
glaciate, glaciates
1. To cover with ice, snow, or a glacier.
2. To become frozen and covered with glaciers.
3. To affect something by the action of a glacier, especially by erosion.
4. To freeze.
5. To produce glacial effects upon, as in the scoring of rocks, transportation of loose material, etc.

Glaciated rocks are those rocks whose surfaces have been smoothed, furrowed, or striated, by the action of ice.

glaciated
1. Covered with ice (as by a glacier) or affected by glacial action.
2. Covered, or having been covered, by glaciers or ice sheets.
glaciation
1. The process of covering the earth with glaciers or masses of ice.
2. The condition or result of being glaciated.
glacier (s) (noun), glaciers (pl)
1. A huge mass of ice slowly flowing over a land mass, formed from compacted snow in an area where snow accumulation exceeds melting: A glacier moves slowly outward from the center of accumulation or down a mountain slope, or valley, until it melts or breaks away.
2. Etymology: from Latin glacies, "ice"; from French glacier, "ice".
glacierization
The covering of a land area by glacier ice.

This term was coined by G. Taylor in the Antarctic and introduced by Wright and Priestly (1922) to distinguish the act of glacial inundation from its geologic consequences (glaciation).

It is growing in use in Great Britain but it still is considered unnecessary by some American geologists, who use the term "glacier covering".

glaciofluvial
Used of sediments transported by ice and deposited from the melted waters of a glacier.
glaciologist
One who specializes in the scientific study of glaciers and their phenomena.
glaciology
The scientific study of the formation, movements, etc. of glaciers.
glacious
Referring to, consisting of, or resembling, ice; icy.
