What is a glacier's relationship with the surface gradient?
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
