Avalanches :: essays research papers

Avalanche Testing and Safety exsanguinous soft fluffy cytosine, hard to imagine something so innocent could be so destructive. Just picture a few tons of snow traveling down the skunk at approximately 80 miles per hour, taking down e verything in its path. Avalanches give birth been a threat as great as there has been snow and mountains. Since Im an avid backcountry skier it is beta to learn about these life threatening snow masses. So in order to protect yourself from anything you must first learn how it works.First bump off there is three main components to an avalanche, without them you cant have an avalanche. They go as follows 1) snow 2) slope 3) snow instability. Secondly, there are deuce harmings of avalanches slab and loose snow. Loose snow are minor and unremarkably never exceed 20 miles per hour. While slab avalanches are the destructive and deadly mountain slides. It is not uncommon for one of these to destroy a small townspeople or forest. Since loose snow avala nches arent very dangerous, I impart discuss slab avalanches. The fundamentals of how these snow masses occur, what to look for when testing and right all-together prevention.The basic chemistry behind a slab avalanche is when one grade of snow does not bond to the layer below it. Any kind of temperature change, fresh snowfall, the weight of a person, all can cause the slab to violate free from the lower layer. The formation of a slab is possible in more ways. One way is for the snow to develop a novelty and therefore there be more snowfall. Since snow doesnt bond to the crust it becomes a potential for an avalanche zone. Another way is for surface canescent to develop, or large ice crystal on the snow. This is usually caused by condensation on the snow surface. This will also have scummy bonding characteristics, and cause for a potential slide. The crystal itself is also very stable and will stay in that formation until melted usually. Slab avalanches usually only occur be tween 35-45 degree slopes and on a saucer-shaped slope. There are ways possible to test for an avalanche zone. These tests have been developed over the years by ski patrollers, avalanche safety, and flavour mountaineers. Make sure whenever performing an avalanche test you are not in an area where you could possibly trigger or be in the path of an avalanche.The most common test to use is the shear test.
