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!

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.
Why glaciers in Antarctica dangerous?
For humans, the most dangerous aspect of glaciers in Antarctica are the crevasses that develop as the glaciers slide off the continent. They are largely invisible until you step into one. Rescue is hours, perhaps days away; full service hospitals are a day or two away and finally, death from hypothermia is nearly guaranteed.
What words could be related to fissures?
Cracks, splits, openings, crevasses.
