What are the cracks in the ice that forms a glacier?
The cracks in an ice glacier are called crevasses. They form due to the movement of the glacier over uneven terrain, causing the ice to fracture and crack. Crevasses can be dangerous to climbers and hikers as they can be deep and difficult to see.
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.
Why do crevasses form on the surface of glaciers?
Crevasses form on the surface of glaciers due to differential movement of the ice. As glaciers flow over uneven terrain, areas of tension and compression develop. These areas of tension can create crevasses, which are deep cracks in the ice caused by the glacier's movement.
What is a large crack that forms when a glacier picks up speed called?
A large crack that forms when a glacier picks up speed is called a crevasse. Crevasses occur due to differential movement within the glacier, often resulting from variations in ice thickness or changes in slope. These cracks can be quite deep and pose hazards to climbers and explorers in glacial regions.

What are the cracks in the ice that forms a glacier?

Why are crevasses dangerous?
Crevasses are formed due to tensile forces overcoming the cohesive strength of the ice. They form perpendicular to the principle stress. So depending on what is happening to the Glacier Ice, different types of crevasses can form. Chevron crevasses form from high friction with the valley sides. Transverse crevasses form from extending ice flows. And splaying crevasses form under compressive ice flows. Hope this helps!
What are the deep clefts found in the top of a glacier?
Crevasses
What did john Muir find in crevasses?
streams that fed the rivers
Why are the uppermost 50 meters of a glacier referred to as the zone of fracture?
The zone of fracture experiences tension hen the glacier moves over irregular terrain. This tension results in gaping cracks called crevasses. Crevasses can be 50 meters deep. They are often hidden by snow and make travel across glaciers dangerous.
What words could be related to fissures?
Cracks, splits, openings, crevasses.
Why the mouse pointer of windows is always tilted?
To get into the corner or the crevasses of the screen.
What did John Muir find in most crevasses?
