What term describes open fissures in the brittle surface ice of a glacier?

The term that describes open fissures in the brittle surface ice of a glacier is crevasse. Crevasse formation is typically due to the movement of the glacier over uneven terrain, leading to cracks in the ice. They can be dangerous for mountaineers and hikers as they are often hidden under snow.
