It flows parallel to it 1 of 5 Why do the centre and surface of a glacier move faster than the sides and base? Due to friction from the surrounding valley 2 of 5 Rate, amount and type of movement are affected by what two factors? Thermal regime and gradient of ice surface 3 of 5 As Ice flows over a steeply sloping bed, movement is likely to speed up, resulting in a thinner glacier with crevasses – an area of: Extending flow 4 of 5 As Ice flows over a gentler gradient it decelerates and backs up, creating an area of: Compressing 5 of 5
