The pressure or force exerted on a glacier due to a down-slope
Shear Stress
1 of 8
The pressure or force exerted on a glacier that is perpendicular to the surface
Normal Stress
2 of 8
Movement by dislocation of individual ice crystals
Internal Deformation
3 of 8
Ice deforming around obstacles in the glacier’s path
Basal Creep
4 of 8
Smaller obstacles cause a build up of pressure that causes melting. Meltwater flows over the obstacle and re-freezes on the other side where pressure is lower
Regelation Slip
5 of 8
Pressure from the weight of the ice causes sub-glacial material to deform and move the overlying ice
Sub-Glacial Bed Deformation
6 of 8
Periods of rapid movement as the glacier snout advances up to a thousand times faster than normal
Glacial Surges
7 of 8
An artery of fast flow surrounded by slower flow
