Glacial Formations


	Basal Sliding	Slipage
	The base moved due to the temperature of the base Warm-based glaciers move by basal sliding due to the creation of meltwater	Ice moves over the valley floor due to meltwater reducing friction between the base of the glacier and the valley floor
	Creep or Regelation	Bed Deformation
	Ice deforms due to obstacles on the valley floor, spreads over obstacles and refreezes over it	Ice is carried by saturated bed sediments It is like it is moving on roller skates

Ice moves over the valley floor due to meltwater reducing friction between the base of the glacier and the valley floor
