Internal deformation

?
What is intergranular flow?
where individual grains of ice slip move in relation to each other re-orientating themselves
1 of 6
What is laminar flow?
Individual layers of ice move in relation to each other
2 of 6
what is ice movement by internal deformation affected by?
gradient
3 of 6
why are crevasses formed?
when ice fractures due to ice not moving fast enough over steep slopes
4 of 6
What is extended flow?
When the gradient increases and the fractured ice accelerates and becomes thinner
5 of 6
What is compressional flow?
When there is a reduction in gradient so the ice slows and becomes thicker
