The Dangers of Avalanches Essay

Avalanches are probably, the biggest danger to, plants, animals, and humans that live in the alpine biome.They will always kill some plants and animals, but sometimes they can also kill humans.

POW! At what seems like 100 miles per hour it hits you! The cold snow running down your back, chills form on your arm. Then, another one! Quickly you dodge it, then grab your own and send it flying back. Wow, you think, snowball fights are extreme. This snowball fight was the best I ever had. We were throwing snowballs across the street, hitting houses and laughing as we do so.

If you live in a place that gets cold in the winter, you've probably seen trucks out spreading a mixture of sand and salt on the streets after a snowfall to help de-ice the road. Have you ever wondered how this works? This basic

The snow on the Rocky Mountains is been melting in the river upper basin, causing snow runoffs to originate.

And sometime the snow would be lift clean from the ground and up into the air, and by and by it would be all clapped to the ground as though there had been no wind at all, straightaway it would rise and fly again.

The volume of snowpack in a water shed exists as snow on the surface during the winter and as it melts, it feeds

When people are on winter break, most want to go out and play in the snow, but who knew that the snow could be one's worst nightmare when stubbornness comes into play. Most people go out on an enjoyable snow-white day to sled down snowy hills and fling semi-hard snowballs at each other. No one would think that maybe sledding down the snowy hills could be so dangerous when they are having fun, and trying to show off. I certainly did not think that it was dangerous, but boy was I so wrong. Normally being a Los Angeles girl, going up to Big Bear is such an amazing experience, because down in the Los Angeles region it does not snow at all. However, I was not ready to face what was slowly going to change me in the mountains of California.

Below freezing air is used to make snow and snowflakes. Moisture from lakes and oceans to form clouds.warm, rising air to form precipitation.

Frost forms when there is enough moisture in the air and the ground is cold to

Another effective technique the author uses is referencing examples of inherent dangers in regard to avalanches. The author references three cases in which avalanches occurred on ski areas to show how avalanches themselves are unpreventable from occurring. This helps benefit the argument since it emphasizes the reality of ski patrollers being helpless when avalanches occur and therefore something that is unavoidable.

In a thousand spots the traces of the winter avalanche may be perceived, where trees lie broken and strewed on the ground; some entirely destroyed, others bent, leaning upon the rocks of the mountain or transversely upon other trees. The path, as you ascend higher, is intersected by ravines of the

In numerous countries it snows, snow can interfere with people’s life, children are unable to attend school and other people are unable to get to their jobs in certain cases when the snow is severe. For these specific reasons snow has to be melted, although there are other ways that they can get rid of snow but this investigation is focusing on melting the snow. De-icing or anti-acing is the process of removing snow, ice or frost from roads, airport runways or any other part needed. To de-ice salt is spread by snowplows or dump trucks, this salt will often be mixed with sand, another component that melts ice. Salt and sand are used as they are inexpensive and are available in large quantities.

The avalanche was believed initiated from the mountain of Grieskogle, which is 1170-metre higher above the village of Galtür at around 4pm. It penetrated the boundary of the village and came to peace in just a few minutes. The whole event lasted less than 3 minuets, resulting the death of 31 people including tourists and local residents, and destructed half of the village. It was believed that 11 houses were completely buried in the avalanched; 17 further houses were partially destroyed or damaged. The speed of the snow powder in the upper layer reached top

They are known as rime and clear ice, and a mixture of the two is not uncommon. For rime ice to form, an aircraft needs to fly through an area of tiny super-cooled liquid drops. This super-cooled liquid is actually suspended in the cloud cover at temperatures already below freezing. Once the aircraft surface plows through this moisture, the drops are disrupted immediately adhere to and freeze before spreading out over the entire surface. This forms a rough and cloudy-white layer of ice known as rime. Even though the rime surface is rough and creates an airflow disturbance, it is lighter and easier to remove by deicing equipment than clear ice. For clear ice to form, larger sized super-cooled drops would need to be encountered. These larger droplets spread out over the surface and airfoils before freezing. This allows for the build-up of a clear, hard and slick layer of ice on the surface (Ahrens, 2009).
