Most of the Western Cordillera was built between about 170 million and 40 million years ago when lithospheric plates converged with North America at rapid rates of many tens to more than 100 millimetres (4 inches) per year. The Juan de Fuca Plate is the last remnant of one of these plates. The North American Cordillera, sometimes also called the Western Cordillera of North America, the Western Cordillera or the Pacific Cordillera, [1] [2] is the North American portion of the American Cordillera, the mountain chain system ( cordillera) along the western coast ( Pacific coast) of the Americas.

(more) The Middle Rockies cover most of west-central Wyoming. Most of the ranges resemble the granitic upwarps of Colorado, but thrust faulting and volcanism have produced varied and spectacular country to the west, some of which is included in Grand Teton and Yellowstone national parks. Physiographic Regions Canada has seven physiographic regions. These regions are the Canadian Shield, the Western Cordillera, the Canadian Arctic, the Appalachian Region, the Interior Plains, the Hudson Bay Lowlands and the St. Lawrence Lowlands. (map by The Canadian Encyclopedia) Canadian Shield The American Cordillera is a chain of mountain ranges ( cordilleras) that consists of an almost continuous sequence of mountain ranges that form the western "backbone" of the Americas. [2] Aconcagua is the highest peak of the chain. It is also the backbone of the volcanic arc that forms the eastern half of the Pacific Ring of Fire . The Western Cordillera was formed roughly 80 million years ago by the North American plate and the Pacific Plate colliding, The western Cordillera is attached to the pacific ocean because of the collision. In the rocky Mountains there are also many types of rock such as Gold, Silver, Zinc, Led, and fossil fuels such as coal, gas, and oils.

December 13, 2020 The Western Cordillera is located in western Canada, from north to south. The major cities are Vancouver, Victoria, Whistler and Whitehorse. Cordillera. A cordillera is an extensive chain and/or network system of mountain ranges, such as those in the west coast of the Americas. The term is borrowed from Spanish, where the word comes from cordilla, a diminutive of cuerda ('rope'). The term is most commonly used in physical geography [1] and is particularly applied to the various. The Western Cordillera consists of mountain ranges that are separated by other mountains , valleys and plateaus . It also includes coastal islands in the pacific. Economy Source A main source of the economy is tourism. The mountains found there bring in loads of tourism. Logging/ goods producing, fishing, mining and oil. On the North American continent, the westernmost physiographic region that extends from Mexico to Alaska is commonly called the Western Cordillera, Cordilleran region, or simply Cordillera. The Canadian portion of this system includes the Rocky Mountains and the Coast Mountains .

physiography of North America In North America: The Cordilleras Taking up about one-third of North America, the Cordilleras completely dominate Alaska and Central America and swell out widely in the United States as the Rocky Mountains. Read More stratigraphy of Cambrian Period In Cambrian Period: Types and distribution Early History The North American continent, of which Canada represents the northern half, was assembled from continental fragments by the process of plate tectonics. Scientists think that this process started more than 3 billion years ago, when the production of continental crust first began.
Western Cordillera - had been a passive (rifted) margin since the Proterozoic - by Devonian it became an active (subduction) margin (Devonian Antler Orogeny in Nevada) - small orogenies (Sonomian and Nevadan) occurred during the Triassic through Cretaceous as the result of the accretion of exotic terranes Major oxide and trace element, including REE data from the Western Cordillera, Cauca - Patía Valley and the Central Cordillera of Colombia.

The Western Cordillera is located on the west coast of Canada, and is present in the Yukon Territories, British Columbia, and western Alberta. This landform region of Canada was formed roughly 80 million years ago in the Mesozoic Era by the encounter of the North American Plate and the heavier Pacific plate. The Western Cordillera formed due to the subduction zone that lies off the west coast of North America. Subduction is the process in which one tectonic plate moves beneath another and is pushed down into the Earth's interior, causing the seafloor to be pushed up and forming mountains. The subduction zone off the west coast of North America is.
