Basal sliding

Glacier motion occurs from four processes, all driven by gravity: basal sliding, glacial quakes generating fractional movements of large sections of ice, bed deformation, and internal deformation. • In the case of basal sliding, the entire glacier slides over its bed. This type of motion is enhanced if the bed is soft sediment, if the glacier bed is thawed and if meltwater is prevalent. 웹Basal glidning er handlingen af en gletscher, der glider over sengen på grund af smeltevand under isen, der fungerer som et smøremiddel.Denne bevægelse afhænger meget af …
