What is the name of major mountain range of North America? In which part of the continent is it located?
Answers
Rocky Mountain in West
Appalachian Mountain in East
Answer:
Rocky Mountains, byname the Rockies, mountain range forming the cordilleran backbone of the great upland system that dominates the western North American continent. Generally, the ranges included in the Rockies stretch from northern Alberta and British Columbia southward to New Mexico, a distance of some 3,000 miles (4,800 km). In places the system is 300 or more miles wide. Limits are mostly arbitrary, especially in the far northwest, where mountain systems such as the Brooks Range of Alaska are sometimes included. The Rockies are bordered on the east by the Great Plains and on the west by the Interior Plateau and Coast Mountains of Canada and the Columbia Plateau and Basin and Range Province of the United States.

The Rocky Mountains include at least 100 separate ranges, which are generally divided into four broad groupings: the Canadian Rockies and Northern Rockies of Montana and northeastern Idaho; the Middle Rockies of Wyoming, Utah, and southeastern Idaho; the Southern Rockies, mainly in Colorado and New Mexico; and the Colorado Plateau in the Four Corners region of Utah, Colorado, New Mexico, and Arizona. These four subdivisions differ from each other in terms of geology (origin, ages, and types of rocks) and physiography (landforms, drainage, and soils), yet they share the physical attributes of high elevations (many peaks exceeding 13,000 feet [4,000 metres]), great local relief (typically 5,000 to 7,000 feet in vertical difference between the base and summit of ranges), shallow soils, considerable mineral wealth, spectacular scenery from past glaciation and volcanic activity, and common trends in climate, biogeography, culture, economy, and exploration.

Physiography
Beartooth Mountains, Montana
The Canadian Rockies include the Mackenzie and Selwyn mountains of the Yukon and Northwest Territories (sometimes called the Arctic Rockies) and the ranges of western Alberta and eastern British Columbia. The Northern Rockies include the Lewis and Bitterroot ranges of western Montana and northeastern Idaho. These ranges formed along the eastern edge of a region of carbonate sedimentation some 17 miles (27 km) thick, which had accumulated from the late Precambrian to early Mesozoic time (i.e., between about 1 billion and 190 million years ago). This structural depression, known as the Rocky Mountain Geosyncline, eventually extended from Alaska to the Gulf of Mexico and became a continuous seaway during the Cretaceous Period (about 145 to 66 million years ago). The ranges of the Canadian and Northern Rockies were created when thick sheets of Paleozoic limestones were thrust eastward over Mesozoic rocks during the mountain-building episode called the Laramide Orogeny (65 to 35 million years ago). Some of these thrust sheets have moved 20 to 30 miles (32 to 48 km) to their present positions. The western margin of the Canadian Rockies and Northern Rockies is marked by the Rocky Mountain Trench, a graben (downfaulted, straight, flat-bottomed valley) up to 3,000 feet (900 metres) deep and several miles wide that has been glaciated and partially filled with deposits from glacial meltwaters.
Columbia Icefield
The Columbia Icefield is situated on the continental divide in the Canadian Rockies at elevations of 10,000 to 13,000 feet (3,000 to 4,000 metres) above sea level. It includes the large Athabasca Glacier, which is nearly five miles long and about a mile wide. Glaciers in this ice field, while continuing to move, are thinning and retreating. The Canadian Rockies are about equally divided between drainage to the east (Atlantic and Arctic oceans) and west (Pacific Ocean).
