Which term refers to a deep, open crack, especially in a glacier?

Explanation:
Think about the specific feature described: a deep, open crack that forms in moving ice. The correct term for that is crevasse. Crevasses arise where the glacier’s ice is pulled apart as it flows, creating fissures that can be very deep and wide. They’re common where the ice is stretching or bending and can be hidden under snow bridges, making them hazardous for climbers and travelers. The other words don’t fit: preclude means to prevent something; congealed means solidified; iota means a very small amount. So crevasse is the precise term for that glacier crack.
