Term	Definition	Contributor	Modified
Glacial till	Accumulations of unsorted, unstratified mixtures of clay, silt, sand, gravel, and boulders; the usual composition of a moraine.	GCW Glossary	2023.03.27
Glacial trough	Large area, such as those in the Alps, carved out to depths of hundreds to thousands of meters by the erosive action of glaciers.	GCW Glossary	2023.03.27
Glacial trough	A large u-shaped valley formed from a v-shaped valley by glacial erosion.	GCW Glossary	2023.03.27
Glacial trough	A glaciated valley or fjord (q.v.), often characterised by steep sides and a flat bottom, with multiple basins, resulting primarily from erosion by strongly channelled ice.	GCW Glossary	2023.03.27
Glacial trough	A deep U-shaped valley with steep valley walls that was formed from glacial erosion. At the base of many of these valleys are cirques.	GCW Glossary	2023.03.27
Glacial uplift	Upward movement of the Earth's crust following isostatic depression from the weight of the continental glaciers.	GCW Glossary	2023.03.27
Glacial valley	Valley that was influenced by the presence of glaciers. The cross-section of such valleys tends to be U-shaped because of glacial erosion. Similar to glacial trough.	GCW Glossary	2023.03.27
Glaciated	Land covered in the past by any form of glacier is said to be glaciated.	GCW Glossary	2023.03.27
Glaciated	Land presently or formerly covered by any form of Glacier is said to be Glaciated.	GCW Glossary	2023.03.27
Glaciated	The character of land that was once covered by glacier ice in the past (cf. glacierised).	GCW Glossary	2023.03.27
Glaciated	Land covered in the past by any form of glacier is said to be glaciated (cf. Ice covered).	GCW Glossary	2023.03.27
Glaciated	Covered by glacier ice in the past, but not at present. See glacierized, which refers to present-day coverage.	GCW Glossary	2023.03.27
glaciation	The process of glacier ice gain.	Ryan McGranaghan	2023.04.16
Glaciation	1.Alteration of any part of the earth's surface by passage of a glacier, chiefly by glacial erosion or deposition; distinguish from glacierization. 2.As used in many texts, particularly with respect t o the ice ages, same as glacierization, for example, "Pleistocene glaciation." 3.The transformation of cloud particles from supercooled water drops to ice crystals. Thus, a cumulonimbus cloud is said to have a glaciated upper portion.	GCW Glossary	2023.03.27
Glaciation	The transformation of cloud particles from water drops to ice crystals. Thus, a cumulonimbus cloud is said to have a 'glaciated' upper portion.	GCW Glossary	2023.03.27
Glaciation	Transformation of cloud droplets into ice crystals, e.g. as occurring in the upper portion of a cumulonimbus.	GCW Glossary	2023.03.27
Glaciation	No definition provided	Ryan McGranaghan	2023.04.16
Glaciation level	In any small glacierized region, the average of the elevations of the highest unglacierized peak and the lowest glacierized peak. The glaciation level has been used as a regional-scale proxy for the s teady-state ELA, although a correction is required for this purpose because the glaciation level is known to be systematically higher by about 200 m. See mid-range altitude.	GCW Glossary	2023.03.27
Glaciation limit	1.For a given locality, the lowest altitude at which glaciers can develop. 2.Same as glacial maximum.	GCW Glossary	2023.03.27
Glaciation limit	A less-used synonym of glaciation level.	GCW Glossary	2023.03.27
