Definition of glaciation in English:

glaciation

noun ˌɡleɪsɪˈeɪʃ(ə)nˌɡleɪʃiˈeɪʃ(ə)n

mass nounGeology

1The process or state of being covered by glaciers or ice sheets.
Example sentencesExamples
- Are these sea-level changes caused by continental glaciation?
- He concluded that discontinuity patterns resulted from ecological and geological barriers at high elevations, attributable mostly to the effects of glaciation and volcanism.
- In Illinois, levels of diversity drop precipitously, most likely reflecting one or more genetic bottlenecks in areas that were once covered by the Wisconsin glaciation.
- Geologically young, the Rockies exhibit faulting, glaciation, and volcanism, resulting in rugged, spectacularly scenic terrain.
- These hydrogeological conditions are controlled by relative land and sea level, erosion and deposition, the cold climate processes of permafrost and glaciation, and rock stress changes.
1. 1.1count noun A glacial period.
  Example sentencesExamples
  For instance, during the Pleistocene glaciations, the high altitude areas were probably nearer to distinct kinds of open vegetation, while forests were retracting.
  An alternative view on uplift and climate change proposes that the Quaternary glaciations in the Himalayas could have enhanced uplift.
  During periods of glaciations followed by periods of thaw it is thought that the river was flowing at such a speed it was able to carry gravel from the glaciers and ice fields to the north and west.
  Similar deposits that accumulated during earlier glaciations occur at various levels in the geological column.
  Their study by others led to the discovery of multiple glaciations, separated by interglacial periods.
  A final chapter reviews recent speculations on the causes of global glaciation.
  However, there have been at least four significant glacial episodes prior to the Pleistocene glaciations.
  During Pleistocene times this resulted in a glacial climate and widespread continental glaciations in high latitudes.
  The first extinction of the Precambrian, which largely affected stromatolites and acritarchs, has been correlated with a large glaciation event that occurred about 600 million years ago.
  Then came a warmer period between glaciations, and the stalactite grew.
  Under these periods of glaciations, the seas would fall to levels about 400 feet below the present.
  ‘Geologically, it would be about 10,000 years old, as the last glaciations meant that entire area was covered with glaciers,’ he said.
  We've had glaciations and we've had warmer periods, and vegetation would creep back as the glaciers were retreating.
  No polar glaciations are known during the Late Permian.
  Silt and varved clay, probably deposited during the last stages of Pleistocene glaciation, cover the entire floor.
  The Upper Palaeolithic occupies the second half of the last glaciation, ending 10,000 years ago.
  Minor glaciations may also have taken place in the earlier Ordovician early Silurian and late Devonian.
  The reason the large animals did not die out at the end of previous glaciations is because there were no previous glaciations.
  A popular view is that during the last glaciation a large ice sheet formed over the Tibetan plateau and that this ice sheet caused a similar split in jet-stream flow.
