The Main Physical Processes in a Peri-Glacial Area Currently 20% of the earth is peri-glacial; therefore we can assume that 20% of the earth’s processes are peri-glacial. The dominant process is that of freeze thaw weathering, which occurs due to fluctuations in temperatures around 0°C, these fluctuations can occur periodically in seasons, or variations between day and night variations. Freeze thaw is concerned with the fact that as water freezes, it expands by 9% exerting pressures of
Fluvioglacial Landforms landforms deposited by meltwater from glaciers. some found within the glacier and some under the glacier. outwash plains- composed of sand, gravel and clay (from snout). deposited during times of inc. ablation (glacial retreat). material is sorted by meltwater at the snout. as it moves away carrying capacity decreases so less is carried. varves- layer if silt on top of sand on top of coarse material. form where there was a glacial
There are many different glacial landforms created by glacial erosion, one of these landforms is U-shaped valleys or glacial troughs. This glacial landform has many distinct characteristics. One of these characteristics is that it has very steep valley sides caused by the glacier as it moves down the valley eroding the sides of the valley by the processes of abrasion and plucking. Abrasion is when the boulders and moraine carried by the glacier rubs and erodes the valley side as it physically moves
Chapter 1: Regions of Canada describe regionalism and how it divides countries, specifically Canada, naturally into six regions: British Columbia, Western Canada, Territorial North, Ontario, Quebec, and Atlantic Canada. These regions have been divided in a manner that correlates ‘like spaces’ in regards to human and physical geography (Bone, p.6) along with Canada’s historical development. The second key feature of chapter 1 describes Canada’s faultlines and they’re affects on Canada’s regional divide
Target Group Haagen Dazs has differentiated its target group from the start of its growth. While the ice-cream industry was considered worldwide as a low price industry and mostly targeting in small ages, Haagen Dazs has from the start been focus on adults, who love the luxurious ice cream flavors. An important reason for taking this choice has been their premium price strategy, since only the financially independent adults could spend more money for high quality ice creams. The second target market
The History of Indigenous Peoples in America Native American is the term used for the indigenous peoples of North America who first migrated to this area thousands of years ago. The term Native American actually includes several tribes, states, and ethnic groups some of which are still recognized in today’s modern society. Most of the scientific world agrees that the first indigenous peoples crossed the Bering Straight by way of Siberia about 12,000 years ago. The precise route that the first
