What is the difference between a crevice and crevasse?
Crevices are cracks or splits caused by a fracture of a rock, while a crevasse is a deep fracture in a glacier or ice sheet. Crevasses form in the top layers of a moving glacier, usually because some parts of the massive body are moving at a different pace than the rest.
How would you describe a crevasse?
A crevasse is a deep, wedge-shaped opening in a moving mass of ice called a glacier. Crevasses usually form in the top 50 meters (160 feet) of a glacier, where the ice is brittle.
What is at the bottom of a crevasse?
A bottom crevasse is, of course, filled with water. This water must freeze continuously to the walls of a bottom crevasse within a cold ice mass if there is no appreciable circulation of water into and out of the crevasse.
Is it pronounced crevice or crevasse?

What to do if you fall in a crevasse?
If you fall in a crevasse you can use the ice screw to secure yourself so you don’t fall deeper. The pulley and carabiners are for rescuing others. Two ice tools, crampons, rope, and several ice screws (basically, ice climbing gear) may allow you to climb out yourself.

What happens if you fall in a crevasse?
The victim may be injured and/or disoriented from the fall, the rescuers on the scene may be anxious or uncertain, equipment and ropes are scattered everywhere, and everybody will likely already be exhausted and out of breath because of the climbing and altitude.
How do people fall into crevasse?
Because of the frequency with which climbers break through the snow over a crevasse and fall in, crevasse rescue technique is a standard part of climbing education. The single-pulley technique entails dropping a pulley attached to another length of rope, which the victim clips to the climbing harness.
How do you spot a crevasse?

How does a crevasse formed?
A crevasse most often forms as a glacier passes over a steeper incline . This causes more stress at the surface of the glacier until is separates, forming a crevasse. A crevasse can also form where a valley widens, causing the glacier to spread.
What is a glacial crevasse?
Crevasse is a Glacial Fracture. A crevasse is a crack, crevice, or fracture in a glacier or moving mass of ice that forms from the movement and stress of the glacier, especially as it moves downhill. Stress in the ice caused by the glacier’s movement causes crevasses to open and close.
