Which term refers to a glacier crack or crevice?

• A. Crevasse
• B. Cairn
• C. Iota
• D. Mangled

Answer: (A)

Crevasses are cracks or crevices in glaciers that form when the flowing ice is subjected to tensile stress and fractures. As a glacier moves over uneven terrain or bends around obstacles, different parts of the ice slide at different speeds, causing the surface to crack. These cracks can be deep and long, and snow can hide many of them, making them a serious hazard for anyone traversing the ice. Other terms don’t describe glacier features: a cairn is a pile of stones marking a trail, iota means a tiny amount, and mangled describes something damaged. So crevasse is the correct term.
