Answer:
The Khumbu glacier moves very rapidly, and crevasses open quickly. ... Crevasses can create seracs, which are also dangerous to mountaineers.Crevasses, which are usually deep, steep, and thin, are a serious danger for mountaineers. Sometimes, a thin layer of snow may form over a crevasse, creating a snow bridge. Snow bridges blend in with the surrounding landscape, hiding the crevasse. Thin snow bridges usually cannot hold a person's weight, so mountaineers secure themselves to each other with rope. All experienced mountaineers are trained in crevasse rescue.
Answer:
A crevasse is a deep crack or fracture found in a glacier or an ice sheet . It is formed in a valley glacier when the glacier negotiates a bend and moves downslope. A crevasse may be covered but not necessarily filled with snow . The loose cover of snow make them invisible and thus they creates a problem for the mountaineers who attempt to navigate their way across a glacier
