Although an avalanches can take place (given the required environment) on any slope, certain locations and certain times of the year are usually more hazardous than others. Most avalanches are likely to happen during wintertime, chiefly from December to April. However, fatalities due to avalanches happen all year. Only thing that is needed for an avalanche to form is a large bulk of snow and a slope for it to slide down. There are avalanches on many scales, from small to large.
Meteorologist David Zaff observed the scene, “the heavy sustained winds ‘took all the snow off the lake and dumped it onto the Greater Buffalo area, from St. Catharines all the way to Buffalo.’” Hurricane force winds that created subarctic wind chills, and large amounts of snowfall coupled with unusually cold temperatures, culminated to create the proverbial perfect storm. The statistics speak to how horrible the storm really was. In the end it resulted in 300
Blizzards cannot be as accurately predicted as earthquakes or tsunamis. Blizzards usually cover the roads with snow and the snow is so powerful that it can even overwhelm the cars. The winds which occur along with blizzards usually uproot trees. Houses with very thin and soft roofs are easily damaged because of blizzards.
Introduction The frozen land of the Canadian artic stretches north of across the top of North America from Alaska to Greenland. Here, for more than four thousand years have lived the people of the ice, the Innu. For about nine months of a year here it snows. The soil is always frozen just below the surface, and in winter the seas turn into ice.
Alpine tundra has a 180-day growing season, and it is usually below freezing at night. The soil here is well-drained, unlike in the arctic. The alpine and arctic tundras have the same plants, but the alpine tundra has tussock grasses, dwarf trees, small-leafed shrubs, and heaths. Animals such as mammals, birds, and insects are located in the alpine tundra and adapt to the altitude. Mammals that can be found in the area are pikas, marmots, mountain goats, sheep, and elk.
Glaciers are formed when snow falls in the winter, but when the spring comes it does not all melt, so the glacier is what is left behind. Glaciers move down the mountain only a few feet a year though. 20,000 years ago it was so cold that many glaciers could form, but now on a few glaciers do since we have a warmer climate. When glaciers erode on the sides of mountains it is called a horn, because it makes it look like a horn. On one side of Glacier there might be a thunderstorm but on the other there side it might be sunny.
The obvious and most ignorant complaint I’ve received is that it just won’t be cold enough. On the contrary, it will be plenty cold. In the U.S. alone, over 8,000,000 refrigerators are sold each year. Each of these refrigerators averages a temperature of 36 degrees. Using PEMDAS and other high-level AP student complex equations, I have determined that in only one year in the U.S, there is a total of 288 million degrees of cold.
Trees can either be planted or they can be conserved, such as in the building of a ski resort, to reduce the strength of avalanches. In turn, socio-environmental changes can influence the occurrence of damaging avalanches: some studies linking changes in land-use/land cover patterns and the evolution of snow avalanche damage in mid latitude mountains show the importance of the role played by vegetation cover, that is at the root of the increase of damage when the protective forest is deforested, and at the root of the decrease of damage because of the transformation of a traditional land-management system based on overexploitation into a system based on land marginalization and reforestation, something that has happened mainly since the mid-20th century in mountain environments of developed countries Mitigation In many areas, regular avalanche tracks can be identified and precautions can be taken to minimise damage, such as the prevention of development in these areas. To mitigate the effect of avalanches the construction of artificial barriers can be very effective in reducing avalanche
Once the Wisconsin Ice Sheet fully melted, the basic dimensions of the lake were fixed. However, the rocks we see today needed to rebound by about 170 m from the weight of the glacier ice. The last ice age gives Blackstone a surface area of about 5.2 km², a volume of 0.1 km³, a mean depth of just over 20 m, a perimeter of nearly 35 km.
The effects on these resources are changes in the temporal and spatial extent of permafrost, snow cover, glaciers, and lake ice cover. For example, glaciers in Glacier Bay National Park, West of Juneau, have retreated 60 miles and lost nearly 1 mile in thickness. “As a result, less than 30% of Glacier Bay National Park is now covered by glaciers.” Another place experiencing the effects of climate change in Juneau is the Juneau Icefield, which is the 5th largest icefield in the Western Hemisphere and the source of the Mendenhall glacier and 140 other glaciers. Due to warming temperatures, the Juneau Icefield, which covers 1,500 square miles, is in danger of disappearing.
According to the author, the earth has experienced many glaciations throughout its creation. If a continent-sized glacier ever returns to Norther America, it would very likely cover New England, New York, the Great Lakes States, northern Plains, Much of Alaska and about all of
Greeting Fellow tourists My name is Moses Trotman and today i will be talking about the Canadian Shield .Did you know that the Canadian shield is a landform region that covers more than half of Canada ?, located in northeast Alberta, northern Saskatchewan, northern Manitoba, southern Northwest Territories, Ontario, Quebec, and Newfoundland. Weather and Climate The climate in the Canadian Shield region varies throughout the year.
It started at the North Pole and it stretched to the 37th parallel which is along the southern edges of Virginia, Kentucky, and Missouri. The estimated area it covered was around five million square miles, and at parts it could reach up to ten thousand feet thick (Britannica). Even though the lakes in Michigan are proof that the Laurentide Ice Sheet melted, it did so very slowly, and there is even some proof that our ancestors lived in the area underneath where the great lakes are today (draining the great lakes). As it retreated, it carved, and under all of that weight compacted the crust enough to create at least five basins that are now the Great lakes. This created an area in where twenty percent of the world’s fresh surface water resides (TED ED).
