What part of a glacier moves fastest when glacier moves by internal plastic flow?
The center or axis of a glacier generally moves the fastest when the glacier is moving by internal plastic flow. This is due to the greater pressure and thickness of ice at the center, causing it to flow more readily than the slower moving edges and margins of the glacier.
What part of glacier most faster when the glacier moves by internal plastic flow?
When a glacier moves by internal plastic flow, the basal layers, particularly those close to the glacier bed, tend to move faster than the upper layers. This is due to the increased pressure and heat at the base, which causes the ice to deform more readily. Additionally, the flow is often faster in the center of the glacier compared to the edges, as friction with the valley walls slows down the flow.
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 the glacier moves by the internal plastic flow?
The part of a glacier that moves fastest during internal plastic flow is typically the center or the upper layers. This is because the ice at the center experiences less friction from the valley walls compared to the ice near the edges, which is slowed down by contact with the substrate and surrounding terrain. Consequently, the flow is more pronounced in the central region, leading to higher velocities.
What does supraglaciation mean?
Supraglaciation refers to the process of ice formation or accumulation on the surface of a glacier. This can occur through the direct freezing of precipitation, supercooling of liquid water, or refreezing of meltwater on the glacier's surface. Supraglacial ice can influence glacial flow dynamics and play a role in mass balance.

What are 3 types of glacier movement?
Three types of glacier movement are basal sliding, internal deformation, and flow. Basal sliding occurs when the glacier moves over a layer of meltwater at its base. Internal deformation involves the slow movement of ice crystals within the glacier. Flow refers to the overall movement of the glacier downslope due to gravity.
What is internal plastic flow?
Internal plastic flow refers to the deformation of a material without fractures or cracks occurring. It typically happens in ductile materials under high stress and temperature conditions, causing the material to permanently change shape without breaking. This process is commonly observed in metal forming and forging operations.
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.
Why does plastic flow occur only 50 meters below ice?
It takes the weight of that much ice to cause the plastic flow.
What does supraglaciation mean?
Supraglaciation refers to the process of ice formation or accumulation on the surface of a glacier. This can occur through the direct freezing of precipitation, supercooling of liquid water, or refreezing of meltwater on the glacier's surface. Supraglacial ice can influence glacial flow dynamics and play a role in mass balance.
What type of glacier flow in all directions?
Fatty
Will plucking occur if a glacier is NOT advancing?
Plucking can still occur even if a glacier is not advancing. Plucking is more influenced by the presence of meltwater and the freezing and thawing of water in crevasses than the overall advance or retreat of the glacier.
Which river flow slow and it is of ice?
You're describing a glacier.
