The United States, the State of North America, bordering with Canada to the north and Mexico to the south; integral part of the U.S. are still Alaska in the far northwest of North America and the Hawaiian Islands in the Pacific uline canada Ocean; There are 19 924 km coastline on the Atlantic and Pacific Oceans.
Surface of the fourth country in the world, after Russia, Canada and China (according to some sources, uline canada depending on different territory. Coverage, the United States is an area in front of China). It occupies vast expanses uline canada without Alaska and Hawaii uline canada in the Z-direction and wide over 4000 km in the direction of the J-up to 2500 km. In this expanse are geological, geographical, climatic and pedological and vegetation varied areas. Generally from I to Z stretch: the coastal plains along the Atlantic Ocean, which is the end of New York to the wide about 20 km, according to J extending 200 km in Georgia joins the coastal plain that stretches along Mex. Gulf. It was built mainly of sand and clay layers of river origin and glacial drift. Coast in north c. part indented deep estuaries (the largest uline canada Chesapeake Bay) in sr. is part of the flat, while the southern front of her numerous low sand islands and lagoons. On the SE of the peninsula of Florida, low limestone slab indented coastline. According to the inland coastal plain becomes uline canada wavy Piedmont (90-550 m high); border uline canada is called. line falls (Fall Line). Downstream from it are numerous navigable rivers (Delaware, Potomac, James, Savannah, etc.) and on it incurred many early cities. Z of Piedmont rises mountain system uline canada Appalachians (the highest peak of Mt. Mitchell, 2037 m), 2500 km long NE-SW, 200-300 km wide (ugl. constructed of pretkambrijskih and Paleozoic rocks). According Z mountain system was slowly uline canada lowered into the vast plateau (350-550 m) composed of Mesozoic limestone, sandstone and shale. In the north c. is part of the glacial relief, while the middle part of the karst (the longest cave system in the world, uline canada Mammoth Cave-Flint Ridge 530 km long). Plateau by Z and S down to 200-300 m high staircase in the vast central plains (Interior Plains) that extends all the way to the Rocky Mountains (Rocky Mountains) to Z and from the Great Lakes (Great Lakes) on to the coastal plain along Mex. Gulf to J. Geologically, it is a big valley filled with alluvial deposits of the Mississippi and its tributaries. Northern. part of the lowlands formed as glaciers and south were deposited thick layers of loess. Older bedrock partly remained elevated z of the Mississippi (Ozark Plateau, Ouachita Mountains, etc.). J on the valley uline canada continues 100-200 km wide coastal plain along Mex. Gulf (Gulf Plain). Cmdr. part (z of the Mississippi) called the Central Plains Great Plains (Great Plains), uline canada which is a very slow rise of about 300 m asl and the 1600 m asl on the ist. foothills of the Rocky Mountains. River erosion has dissected the large undulating plateaus uline canada above them in the north c. of the rising mountains uline canada of the Black Hills (the highest peak of Harney uline canada Peak, 2207 m), built of old crystalline rocks. Cmdr. Part of the USA takes up to 1600 km wide pleated young Cordillera Mountains (part of a linked mega mountain that stretches along the entire Cmdr. Northern part. and Juz. America). In the Z-direction and in the cordillera uline canada U.S. 5 generally consist of parallel parts (providing S-J): In the Rocky Mountains and mountain wide system to 700 km, which consists of a series of parallel mountain ranges with many peaks above 4000 m ( highest Mt. Elbert, 4399 m). Rocky Mountain passes of the Atlantic watershed uline canada and Tihooceanskog left (Continental Divide). Z of the Rocky Mountains are a mountain levellers and basins: on the plateau Columbia-Snake (1800 m) covered with thick layers of lava, south of spacious Great Basin desert (Great uline canada Basin, about 500 000 km 2) with the Great Salt Lake ( Great Salt Lake) to which the J continues Colorado Plateau (about 340,000 km 2) at altitudes uline canada from 1800 to 3000 he was directed by the famous Colorado incised canyon. Mountain plains and basins Z to delimit Stage mountains (Cascade Range) uline canada and
