| 21. | Therefore, periglacial environments are anywhere that freezing and thawing modify the landscape in a significant manner.
|
| 22. | Sediments, boulders and sands in the cave appear to be from a periglacial or subglacial origin.
|
| 23. | This contrasted sharply with the views of others that tors are essentially arctic features produced by periglacial processes.
|
| 24. | This concept contrasts with periglacial processes, which are directly driven by formation or melting of ice or frost.
|
| 25. | Intense freezing and thawing during the Pleistocene periglacial period slowly shattered the walls, much like breaking tempered glass.
|
| 26. | String bogs are features associated with periglacial climates, where the temperature results in long periods of subzero temperatures.
|
| 27. | These moraines are morphologically quite different from the very widespread stone runs, which are the result of periglacial processes.
|
| 28. | Periglacial processes, such as cryoturbation and stone stripping, occur on Level Mountain at elevations greater than } }.
|
| 29. | Also paleo-soils as well as eolian and periglacial landforms and sediments may be used to find correlations between terraces.
|
| 30. | There are no indications that Cwm Craf on its northern side held a glacier but it is perhaps periglacial in origin.
