Warm based (Temperate) glaciers
Karten in diesem Stapel (8)
- 1How do warm based (Temperate) glaciers mainly move?Basal sliding
- 2How is friction reduced between the ice and the valley floor if temperature is at or above pressure melting point?A thin film of meltwater reduces the friction
- 3What else can can lead to the creation of meltwater?Friction itself from the moving glacier
- 4What is slippage?Where the ice slides over the valley floor as the meltwater has reduced the friction between the base and valley floor
- 5What is creep/regulation?When ice deforms under pressure due to obstructions on the valley floor
- 6What does creep allow the ice to do?It allows the ice to spread around and over the obstruction, rather as a plastic, before refreezing again when
- 7What is bed deformation?When the ice is carried by saturated bed sediments moving beneath it on gentle gradients
- 8What has bed deformation been likened to?The ice being carried on roller skates
