| Similar deposits that accumulated during earlier glaciations occur at various levels in the geological column. |
|
| Minor glaciations may also have taken place in the earlier Ordovician early Silurian and late Devonian. |
|
| An alternative view on uplift and climate change proposes that the Quaternary glaciations in the Himalayas could have enhanced uplift. |
|
| The reason the large animals did not die out at the end of previous glaciations is because there were no previous glaciations. |
|
| During Pleistocene times this resulted in a glacial climate and widespread continental glaciations in high latitudes. |
|
| Under these periods of glaciations, the seas would fall to levels about 400 feet below the present. |
|
| However, there have been at least four significant glacial episodes prior to the Pleistocene glaciations. |
|
| We've had glaciations and we've had warmer periods, and vegetation would creep back as the glaciers were retreating. |
|
| Their study by others led to the discovery of multiple glaciations, separated by interglacial periods. |
|
| Then came a warmer period between glaciations, and the stalactite grew. |
|
| Over the last half-million years or so, warm interglacial periods have been much shorter than the cold glaciations, lasting on average only 10,000 years. |
|
| For instance, during the Pleistocene glaciations, the high altitude areas were probably nearer to distinct kinds of open vegetation, while forests were retracting. |
|
| The later half of the period experienced glaciations, low sea level, and mountain building as the continents collided to form Pangaea. |
|
| The climate was one of periodic glaciations with continental glaciers moving as far from the poles as 40 degrees latitude. |
|
| Icehouse is characterized by frequent continental glaciations and severe desert environments. |
|
| The geology of the archipelago is characterized by the effects of the Andean orogeny and the repeated Pleistocene glaciations. |
|
| The Quaternary glaciation is the last of five known glaciations during Earth's history. |
|
| The area was affected by sea level changes during the repeated Quaternary glaciations. |
|
| The islands have been shaped by numerous glaciations during the Quaternary Period, the most recent being the Devensian. |
|
| The Pleistocene glaciations almost entirely covered Scotland in ice, and Arran's highest peaks may have been nunataks at this time. |
|
|
|
| In common with the rest of Scotland the whole region was affected by Pleistocene glaciations. |
|
| The repeated glaciations of the Pleistocene were caused by the same factors. |
|
| In a paper published in 1824, Esmark proposed changes in climate as the cause of those glaciations. |
|
| Successive glaciations tend to distort and erase the geological evidence, making it difficult to interpret. |
|
| There is evidence that ocean circulation patterns are disrupted by glaciations. |
|
| Ice sheets that form during glaciations cause erosion of the land beneath them. |
|
| There were likely polar ice caps and a series of glaciations, as the planet was still recovering from an earlier Snowball Earth. |
|
| During the Quaternary glaciations, Brittany was covered by loess and rivers started to fill the valleys with alluvial deposits. |
|
| The upper boundary was set at the start of the Pleistocene glaciations. |
|
| At high latitudes and during glaciations, the nearshore morphology of passive margins may reflect glacial processes, such as the fjords of Norway and Greenland. |
|
| Repeated glaciations, which covered the entire land mass of modern Scotland, destroyed any traces of human habitation that may have existed before the Mesolithic period. |
|
| As an example, palynological studies have been used to track changing vegetation patterns throughout the Quaternary glaciations and especially since the last glacial maximum. |
|
| Some believe that the strength of the orbital forcing is too small to trigger glaciations, but feedback mechanisms like CO2 may explain this mismatch. |
|
| The Pleistocene covers the recent period of repeated glaciations. |
|
| Local glaciations existed in the Rocky Mountains and the Cordilleran ice sheet and as ice fields and ice caps in the Sierra Nevada in northern California. |
|
| The glaciations that occurred during this glacial period covered many areas, mainly in the Northern Hemisphere and to a lesser extent in the Southern Hemisphere. |
