Landscapes and Landforms of Eastern Canada

Produktform: Buch / Einband - fest (Hardcover)

As for wetlands there are distinctive Arctic, Subarctic, Boreal, Eastern Temperate and Atlantic wetlands and their extent is second only to those of Russia. In the Hudson and James bay regions between 75-100% of the terrestrial surface is comprised of wetlands. One of North America’s largest river basins, the Great Lakes-St. Lawrence basin, has its source in Minnesota, straddles the USA-Canada border and debouches into Quebec as the St. Lawrence River and evolves through its estuary into the Gulf of St. Lawrence, a journey of almost 5,000 km. As far as meteorite craters are concerned, 10% of the world’s total are located in eastern Canada, including some of the largest and most complex. They are preserved preferentially in the ancient Shield terrain of Quebec. Finally, the three million km² of permafrost controlled relief in eastern Canada serves as a reminder of the vulnerability of eastern Canada’s landscapes to climate change. Effects of warming are expressed through thawing of the permafrost, disruption of transportation corridors and urban construction problems, ever-present geomorphic hazardsweiterlesen
