The most dramatic differences in environmental conditions creates a contrast between the lowland East and the mountainous West of the country. Eastern Canada, wide open to the Arctic ocean, divided into numerous Islands, with deeply cut on South broad Hazanovym the Bay and is constantly subjected to a powerful Arctic air mass intrusion. As a result the tundra zone with sparse vegetation and permafrost formed on 55-57° North latitude, i.e. the latitude of Moscow. In the Central Piedmont part of the country on the same latitude are the canadian prairies and on the Pacific coast, protected by the mountain system of the Cordillera, virtually no winter, and on the mountain slopes develop tall “coastal forest” in which individual trees reach 40 to 60, and sometimes 90 m height. This is the famous sichinskaya spruce, Douglas fir, Western gemlok, etc. a Notable feature of Canada is the development of large lake-river systems. Is the Mackenzie river, carrying water into the Arctic ocean, in the pool which are situated the famous lake Great bear, Great Slave, Athabasca. The other system is the Nelson river, which flows into Hudson Bay, the basin of which includes lakes Winnipeg, Winnipegosis, Manitoba, and many others. The third system is the river St. Lawrence, carrying water into the Atlantic ocean. It includes all five Great lakes. The lakes are connected Continue reading
The lake, mostly concentrated in the Northern half of North America within the boundaries of the Canadian shield and its boundary. A large group of large lake basins, formed in situ tectonic depressions, then wymaganych and in-depth glacier, located on the edge of the Canadian shield. This Huge bear lake, Great Slave, Athabasca, Winnipeg, and Winnipegosis, Forest, Nipigon and, in the end, a group of Majestic lakes . The large number of lakes resembling in their own lakes of Finland and Sweden, is located in the Laurentian mountains. In the Cordillera mountain many lakes, glacial and volcanic origin.
Lakes to Majestic huge 5 includes: Upper, Huron, Michigan, Erie and Ontario . They are associated with a little medium-sized lakes. Important of them are: St. Marys, St. Clair, Nipigon. The lakes belong to the basin of the Atlantic ocean. Stoke on the St. Lawrence river. On the formation of lake basins most influenced by tectonic processes. The weight of the glacier pushed the earth’s crust, and once the glacier melted, began leisurely working process: post-glacial rise (eng. Continue reading
