Glaciers begin to deform plastically at a depth of around 50 to 60 meters (about 164 to 197 feet) below the surface. At this depth, the pressure from the overlying ice is sufficient to overcome the ice's brittle behavior, allowing it to flow slowly and accommodate stress. The exact depth can vary based on factors like temperature and ice composition, but generally, this is the threshold where significant plastic deformation occurs.

What is the deep crack in the surface of a glacier called?
Crevasse! :)
How many meters deep is the Lambert Glacier?
According to its Wikipedia entry: "Lambert Glacier is a major glacier in East Antarctica. At about 60 miles wide, over 250 miles long, and about 2,500 m deep, it holds the Guinness world record for the world's largest glacier."
Fissure or deep cleft in glacial ice?
A crevasse is a deep crack or fissure in a glacier ice. It forms when the glacier moves over uneven terrain or when it is subjected to shearing stresses. Crevasse fields can be dangerous to navigate and require careful glacier travel techniques.
How do glaciers flow?
glaciers move slowly but when theres alot of rain the water and the glaciers move faster
What is a crevasse at the head of a mountain glacier called?
A crevasse at the head of a mountain glacier is called a "bergschrund." This feature typically forms where the glacier begins to separate from the surrounding terrain, often due to differential movement between the glacier and the mountain slope. Bergschrunds can be quite deep and wide, posing challenges for climbers and hikers navigating the glacier.
How do glaciers move for 6th grade?
A continental glacier can move in all directions and a valley glacier can move in a surge. :)
Is it true that due to the force of friction a glacier will start to move downhill once the layer of snow and ice is more than about 30 to 40 meters deep?
Yes, the force of friction between the glacier and the ground is one of the factors that allows glaciers to move downhill under their own weight. This movement occurs once the thickness of the glacier reaches a critical depth where the force of gravity overcomes the frictional resistance. Once this threshold is reached, the glacier will start to flow downslope.
What are the deep clefts found in the top of a glacier?
Crevasses
How do the glacier move?
They melt and then slide

What glacier is the largest?
The world's largest glacier and also the largest in East Antarctica is the Lambert Glacier. The glacier is 60 miles wide, 250 miles long, and 2,500 m deep.

What is crevasse and how does it form?
A crevasse is a deep open crack in a glacier. It is formed when a magma chamber under a glacier causes melting and cracking and causes the glacier to slide into the ocean on the magma
Why do crevasses form in the upper portion of a glacier but not below a depth of about 50 meters?
Crevasses form on the upper portion of the glacier because when a glacier moves over irregular terrain, the zone of fracture is subjected to tension, which forms the crevasse. The reason why it may not form below the depth of 50 feet is because plastic flow seals them off.
