Recommended: Physical characteristics of the Canadian Shield
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
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.
This is a report based on three days of observations and testing in the region known as the Peterborough drumlin field. It will address a variety of regional elements, such as climate, soil, vegetation, hydrology, geomorphology, and geology. A variety of sites located on the Canadian Shield, the zone of thick glacial deposits to the south, and the transition between them will be the focus of the report. It is supplemented with previous research on the region. September 8, 1999, day one of the field study involved an area of largely granite bedrock that is part of the Canadian Shield and is the most northern point of study (see Map 2). September 9, 1999, day two, involved three main areas of study: the Bridgenorth esker (Map 3), Mark S. Burnham Park (Map 4), and the Rice Lake drumlin (Map 6). These sites are in areas of thick glacial deposits. September 10, 1999, day three, involved studying the Warsaw Caves (see Map 5) as a transition zone between Precambrian Shield rock to the north and Paleozoic rock to the south. A general map of the entire study region is provided by Map 1.
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.
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).
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.
Based on Dr. Ralph’s comments, the drumlin has been shaped by glaciers during these separate advances into a lobate form, with one lobe parallel to an early southeastward ice flow from a New Brunswick glacier and another aligned with a later southward flow from an ice cap over the Gulf of St. Lawrence. A rock outcrop next to the drumlin shows crossing scratches or striae made by these glaciers as they scoured the exposed bedrock. The till deposits contain erratic boulders that have undergone a lengthy journey from their home outcrops in the Cobequid Highlands, 100 km to the north, carried by fast-moving rivers of ice called ice
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
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).
All of Maine was once covered by glaciers, the last of which receded about 10,000 years ago. Because of the glaciers, much of Maine is covered with stones, boulders, and clays. Many of the hills and mountains have been rounded, lakes have been formed, and river courses have been changed. Although glaciers covered all of Maine, there are nevertheless substantial physiographic differences in the regions of the state. Maine can be divided into three major natural regions: the White Mountain section, the New England Upland, and the Seaboard Lowland. These three regions are part of the New England province, which in turn forms part of the Appalachian Region.
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.
