Document Summary
Cold, snow and ice remain prevalent features of the climate of higher latitudes and altitudes, and research in geomorphology and paleoclimatology provides ample evidence of substantially greater predominance of such conditions at various times in earth"s past. In this module we examine the distinctive processes and landform features of near-glacial climates, as well as the ways in which. Owing masses of ice shape landscapes through erosion and deposition. Topics covered: periglacial processes and landforms, alpine glacial processes and landforms, continental glaciations and landforms. Textbook readings: complete the following in preparation for the lecture 10: all of chapter 17. Glaciers are de ned as any large natural accumulation of land ice affected by past or present motion. In areas where accumulation is greater than ablation, a new layer of snow is added each year to the glacier surface. This material is gradually compacted to form granular ice crystals known as rn.
