What part of glacier moves fastest when the glacier moves by internal plastic flow?
The central part of the glacier moves fastest than its edges as it is thickest from the center.
What part of a glacier moves fastest when glacier moves by internal plastic flow?
the top layer whic is compacted snow and ice which is about 15m deep
Are glacier's stiff and rigid?
No, Weird huh? When you get that much ice in one place the weight and pressure make it move like a plastic and "Flow" almost like water or Lava. The glacier flows down the valley advancing as it melts.
Does a continental glacier flow in all directions?
yes...
Will plucking occur if a glacier is NOT advancing?
Yes, because glacial ice is still moving inside the glacier even if the glacier's front is not advancing.
What are 3 types of glacier movement?
fracturing, basal slip and plastic deformation or plastic flow :)

What is internal plastic flow?
Until a metal reaches its elastic limit, it is undergoing elastic deformation. This means that the metal will regain its original dimensions when unloaded. Upon exceeding the elastic limit, the metal will become plastic and will not regain its original dimensions. A metal undergoes plastic flow when it experiences large deformations while loaded in the plastic region.

What causes plastic flow to occur?
High pressure
Why does plastic flow occur only 50 meters below ice?
It takes the weight of that much ice to cause the plastic flow.
Why does plastic flow occur only below 50 meters of ice?
It takes the weight of that much ice to cause the plastic flow.
What is The Definition of Plastic flow?
Movement whithin a glacier in which the ice is not fractured- <http://highered.mcgraw-hill.com/sites/0072402466/student_view0/chapter12/glossary.html>
Is a glacier formed by a flow of a river?
No. A glacier is a mass of moving snow and ice.

What is a basal flow?
melting water at base of a glacier
What type of glacier flow in all directions?
Fatty
