What are crevasses?

Crevasses are indeed defined as cracks in the surface of a glacier. As glaciers move, the ice can deform and fracture due to stress and strain. These fractures can occur in various sizes and shapes and are most commonly found in areas where there are changes in the glacier's slope, velocity, or thickness. The formation of crevasses is a key characteristic of the dynamic nature of glaciers, reflecting the internal movement and flow of ice. Understanding crevasses is essential in studying glacial environments as they illustrate the complex processes involved in glaciation and are important indicators of glacier stability and behavior.
