Alberta is a Canadian province. Located in Western Canada, the province has an area of and is bounded to the south by the U.S. state of Montana along 49° north for ; to the east at 110° west by the province of Saskatchewan for ; and at 60° north the Northwest Territories for . The southern half of the province borders British Columbia along the Continental Divide of the Americas on the peaks of the Rocky Mountains, while the northern half borders British Columbia along the 120th meridian west. ==Terrain== Alberta is a fertile province, as the southern portion of its surface consists chiefly of plains that are almost entirely treeless. As the slopes of the Rocky Mountains to the west are reached, more trees are found until in the foothills of the mountains, bodies of forest timber occur. Trees also become more numerous in the northern part of the province, until in the region north of the North Saskatchewan River continuous forests are met with again. From the southern boundary line for 2.5° north the prairie is dry, but of good soil, which grows excellent crops when irrigated. North of this region, the surface of the province is of the most fertile soil, with ordinary rainfall sufficing for agriculture. Alberta also has large oil reserves, especially in the Athabasca Oil Sands in the north of the province. The appearance of the prairie section of the province is that of undulating grasslands, with rounded sloping ridges covered with shorter grasses, which serve for the support of large herds of beef cattle. The wooded portions of the terrain are dotted with clumps and belts of trees of moderate size, giving them a park-like appearance. In winter it is continuously very cold, but this is occasionally reduced by a warm wind from the west, known as the Chinook. A Geological Survey of Canada map published in 1970 shows the following physiographic regions to be present at least partially within Alberta:〔http://r.duckduckgo.com/l/?kh=-1&uddg=http%3A%2F%2Fgeogratis.gc.ca%2Fapi%2Fen%2Fnrcan-rncan%2Fess-sst%2F34acdc40-c813-5a09-aafe-a3470e1e56b5.html〕 *Interior Plains * *Great Slave Plain * *Alberta Plateau * *Fort Nelson Lowland * *Peace River Lowland * *Alberta Plain * *Saskatchewan Plain * *Cypress Hills *Cordilleran Region * *Rocky Mountain Foothills * *Rocky Mountains * * *Continental Ranges *Canadian Shield * *Kazan Region * * *Kazan Upland * * *Athabasca Plain 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Geography of Alberta」の詳細全文を読む スポンサード リンク
