Pickle Lake, Ontario is located in the Canadian Shield landform region. This landform region is the largest region in all of Canada and was formed over 4 billion years ago. This is where most of the metallic minerals are found and there are also igneous and metamorphic rocks found here. It was formed by many different effects, one way was when the molten rock cooled it formed igneous rock creating the Shield. Another one was minerals separated into layers according to their density and then the Shield rock cooled. Then the main one is glaciation and erosion which is/was the cause of most landform creation. There are many physical descriptions of the Canadian Shield first, is there are many small lakes formed by glaciers. Next, there are also
The Bullfrog Valley gang was a notorious counterfeiting ring that operated in the wilderness of Pope County during the depression of the 1890’s.The gang’s origin and and methods were mysterious, but the New York Times reported ist demise on June 28, 1897.The remote valley, which follows Big Piney Creek from Long Pool to Booger Hollow, was named for Chief Bullfrog, a Cherokee Who, according to legend, settled there after his tribe’s forced removal from Georgia (the Trail of Tears by the Indian Removal Act of 1830. The Bullfrog Valley, an unincorporated community not typically recognized on current Arkansas state maps, is located along the Big Piney Creek near the community of Silex. According to Dumas, historically the
Glacial Lake Peterborough had many attributing spillways attached to it, feeding meltwater and sediment from the ice margin and or other glacial lakes. Much of the sediment that was deposited in Glacial Lake Peterborough came from either from the stagnant ice blocks located on the Oak Ridges moraine or from the Lake Algonquin drainage system. Much of the deposition in this lake was dominated by sediment stratification, which may have been largely influenced by thermal stratification. As a result of thermal stratification occurring in this glacial lake sediment inputs were greatly influenced depending on the different sediment densities between the lake bottom water to that of the incoming meltwater and if the inflow density was less/more than the bottom water than the lake water bottom, than new transport and depositional paths were created
The third alluvial deposition consists of sand, silt and minor inter-bedded gravel, and again indicates Brimbank Park’s changing geology over time. (Geological map of Victoria, 1973). These deposits, as well as a nearby fault suggest volcanic activity 5-1.6 million years ago, which explains the olivine basalt (fig. 2) deposits which date back to to the Silurian and Tertiary period.
Nature has a powerful way of portraying good vs. bad, which parallels to the same concept intertwined with human nature. In the story “Greasy Lake” by T. Coraghessan Boyle, the author portrays this through the use of a lake by demonstrating its significance and relationship to the characters. At one time, the Greasy Lake was something of beauty and cleanliness, but then came to be the exact opposite. Through his writing, Boyle demonstrates how the setting can be a direct reflection of the characters and the experiences they encounter.
More specifically, Trois-Rivieres is located in an area with flat and rolling hills, and fertile soils that play a huge part of Trois-Rivieres’s economy. The formation of the Great Lakes-St Lawrence Lowlands happened during the Paleozoic era. “The Great Lakes-St Lowlands were formed by the effects of glaciation. This is caused the city’s rolling landscape where flat plains are interrupted with glacial hills and deep river valleys. After the glacial period, when a large volume of water melted out from the glaciers, the lakes were large, even larger than they are today. However, the lakes shrank to their present size, and flat plains of sediments remained. These sediments formed excellent soil for farming” (Pandya, n.d). This process left behind a large amount of sediment rock, which was beneficial for the manufacturing industry.
Chapter 2: Canada’s Physical Base emphasizes reasoning for which its physical geography attributes to its regional geography, along with the population distribution and developing core regions. This chapter outlines main geological structure, landforms, climate, and impact on human a...
This artic tundra is mainly formed by permafrost, “a layer of permanently frozen subsoil in the ground. Putting frozen ground and flat landscape stops the drainage of water. As the water is being held up on the surface it makes ponds and bogs that give moisture for the plants, or countering the low precipitation. “The periodic freezing and thawing of the soil forms cracks in the ground in regularly patterned polygons”. Some areas are not drained very well causing irregular landforms. Some of these landforms like the following hummocks, or knolls, frost boils, and earth stripes. Another common area to the alpine tundra is a “bare rock covered ground” also known as fell fields, in which not alone support but helps the growth of lichens. The many “microhabitats” given by these landforms provide a variety to the tundra’s landscape.
Boiling Lake is one of the most popular attractions in MorneTrois Pitons National Park. This eerie-looking pool of bubbling, gray-green water lies at the end of a strenuous, three-hour hike through thick forest. But it's worth it. Geologists believe the 63-meter-wide actively boiling lake, the world's second largest, is a flooded fumarole, a crack in the earth allowing hot gases to vent from the molten lava below. The temperature at the edge of the lake ranges from 82-92°C and is at boiling point in the center. After rain, the trail becomes slick and muddy. Guides are highly recommended, (Karen, Hastings).
To everyone that received the perfect pickle picture it came as somewhat of a shock to open the message and see a pickle. Nothing remarkable about it, no twists, or corkscrew shape, not even a
Canada has many geographic region, the largest of it all is the Canadian Shield. The Canadian Shield covers about 4,800,000 kilometres squared, or about 50% of Canada. The Canadian Shield is so big that it also covers some parts of the United States. Also the Canadian Shield is the geographic foundation of Canada. The Canadian Shield has thin soil so it’s ill suited for farming, but it is well suited for the mining industry. Also the Canadian Shield has large amounts of forestry's within its geographic region. It also has scenic river, waterfalls, and lakes. The Canadian Shield has vast amounts of water within its region that it is used for generating energy in hydro plants. And that’s the characteristics of the Canadian Shield, the largest
To tell how healthy a body of water is, you would need to measure the amount of dissolved oxygen (DO) in the water. Water is only able to dissolve a certain amount of oxygen to be classified as healthy. And once, the maximum amount of oxygen from the atmosphere that can dissolve in water, which is about 9.8 mg/l, is reached , no more oxygen will dissolve. This shows that water needs to maintain a certain amount of dissolved oxygen, typically 4-5 mg/l, for it to be classified as healthy and to support aquatic animals. If the dissolved oxygen levels drop below 5.0 mg/l, the aquatic life will be put under stress. The amount of dissolved oxygen in the water is affected by several physical and biological (natural) factors.
Ice Hockey has no official date of origin. However, it was first created in the 1800’s by King’s College School, who adapted a favorite field game called Hurley to make ‘’Ice Hurley”, later changed its name and become known as Ice Hockey. “Thomas Chandler Haliburton, born in Windsor in 1796, told of King’s boys playing “Hurley on the ice” when he was a young student at the school around 1800. This is the earliest reference in English literature of a stick-ball game being played on ice in Canada.” (Vaughan ). Canada is largely assumed to be the “birthplace’’ of ice hockey while some sources point to its unconfirmed origin in Europe. Actually, the game wasn’t introduced in Montreal until 1875 (Vaughan).
The map indicates the solid geology of study area. This area mostly underlain by Low Coal Measures Formation which were intersected by a layer of Crawshaw Sandstone and Rough Rock Formation. Lower Coal Measure Formation mainly underlain at the north part, east part and lower middle part of the study area ie. part of Low Holdworth, Dungworth, Stoors, Loxley Chase, Stannington and River Loxley. The other major geology types of stone underlying the study area are Millstone Grit Group which gathers in the surrounding area of Damflask Reservoir, which contain mudstones and limestone beds. Also, the Rough Rock Formation is interacted with Millstone Grit located at northwest part and middle east part of the study area.
The falls serve as a border between the U.S. (New York) and Canada (Ontario). The falls actually consist of the American Bridal Veil Falls and the Canadian Horseshoe Falls, collectively called Niagara. They were created 12,000 years ago when large glaciers retreated allowing the Niagara River to flow over large sections of rock. There are several ways to view the falls, but perhaps the best way to observe the splendor and majesty of Niagara Falls is through a tour. Our tour guide directed us through many of the unseen attractions including the man-made tunnels behind the falls. Here, several
Weddell Sea located in the west of the Antarctica. The surface of the oceans freezes once it surpasses its threshold of 29 degrees. As the ice in created in microscopic level it releases brine into the solution leaving with tiny holes in the ice and points ends. As winter grips the formation of the ice speeds up and more brine is accumulated on the surface. Each year around 200 Billion tons of ice is created in Weddell Sea alone. The fate of the brine is unknown to the date.
