2. A freezing; a congelation; also, a frost.
2. The removal of land ice from an area; usually by melting.
The process creates an unstratified material of varying composition.
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."
2. Anyone who attributes the phenomena of the drift, in geology, to glaciers.
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.
2. Covered, or having been covered, by glaciers or ice sheets.
2. The condition or result of being glaciated.
2. Etymology: from Latin glacies, "ice"; from French 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".
